Introduction

The purpose of this document is to provide a venue for 5 th grade science teachers to facilitate the discussion of the New Generation Science Sunshine State Standards Annually Assessed Benchmarks in the 5th grade science course. Each lesson plan included in this document is aligned with the assessed benchmarks. The lessons and laboratory activities were developed with the intention of allowing the students to grow in critical thinking within the content of the benchmark.

These labs were developed to enable all 5th grade science teachers to address these very important concepts in their science courses prior to the Science FCAT. The labs were designed to cover the most important tested concepts for which the students will be assessed on the 2012 Science FCAT. Some benchmarks are extremely broad and will address different content foci. Lab activities may also cover multiple benchmarks. The “N Strand” of the Sunshine State Standards, which deals with the Practice of Science, is infused in all labs.

For the most part, the activities were modestly designed without the use of advanced technological equipment to make it possible for all teachers to use these activities. However, it is highly recommended that technology, such as the use of computers be used to access the Internet and to utilize additional resources such as Gizmos at www.explorelearning.com, and Discovery Education.

This document is intended to be used by the 5th grade science teachers so that all teachers within this grade level can collaborate as they work together, plan together, and rotate lab materials among classrooms. Through this practice, all students and teachers will have the same opportunities to participate in these experiences and promote discourse among learners, which are the building blocks of authentic learning communities.

Title: Solar Stretch (Teacher) Benchmarks: SC.5.1.E.5.1 The student knows that the planets differ in size, characteristics, and composition and that they orbit the Sun in our Solar System.SC.5.1.E.5.3 The student understands the arrangement of planets in our Solar System.

The student uses a model to locate the relative positions of all the planets and the asteroid belt as they orbit the sun in our solar system.

The student classifies the planets according to size, characteristics, and composition.

Essential Question : How can we better understand the great distance between planets in the solar system and their position relative to the sun? How can we better understand the great distance between planets in the solar system and their composition relative to the Sun?

BACKGROUND INFORMATIONThe solar system consists of the sun, the planets and their moons, asteroids, meteoroids, thousands of comets, and particles of dust and gas that revolve around the sun. Each of the nine planets spins around an imaginary axis through its center, while also traveling in a clockwise direction around the sun. The word planet comes from the Greek “planets,” which means “wanderer.”

The distances from planet to planet and across the solar system are so large that it is hard to even imagine them. The exact distances between the planets and the sun and between the planets themselves vary because the planets move in oval orbits. The chart below shows the approximate distance from the sun to each of the planets.

Title: Teacher Rainmaker (Teacher) Benchmarks: SC.5.1.E.7.1 The student knows that the water cycle is influenced by temperature, pressure, and the topography of the land.

The student simulates the water cycle. The student explains the stages of the water cycle

(evaporation, condensation, precipitation) to illustrate that when liquid water evaporates, it turns into a gas (vapor) in the air and condenses as a liquid when cooled, or as a solid if cooled below the freezing point of water.

Essential QuestionsHow do temperature changes affect the water cycle?

BACKGROUND INFORMATIONThe water cycle is a never-ending cycle that includes evaporation, condensation, and precipitation. The sun is the energy that keeps the cycle moving. The heat energy from the sun changes water into vapor. This invisible vapor then condenses and forms billions of droplets that make up clouds. The moisture from the clouds returns to the earth as rain, snow, or other forms of precipitation. Temperature plays an integral role in this never-ending process by affecting the rate of evaporation and the type of precipitation (e.g., rain, snow, ice). Topography, the shape of the land caused by differences in elevation, can affect the amount of precipitation an area receives.

Evaporation is the process in which matter changes from a liquid state to a gaseous state (vapor)Condensation is the process in which matter changes from a gaseous state (vapor) to a liquid state. Condensation occurs as air with water vapor in it cools; clouds are evidence of condensation. Precipitation forms when water droplets in clouds become too heavy to stay in the atmosphere. The water droplets fall in some form, such as snow, ice, or rain, to the earth’s surface.

Title: Don’t Pressure Me! (Teacher)Benchmarks:

SC.5.E.7.3The student will recognize how air temperature, barometric pressure, humidity, wind speed and direction, and precipitation determines the weather in a particular place and time

Essential Question:

What is air pressure and why is air pressure an important indicator in predicting weather?

BACKGROUND INFORMATIONAir constantly exerts great pressure, but we don’t feel it because the pressure is exerted in all directions. At sea level, this pressure is about 15 pounds per square inch. Air pressure is caused by the weight of the pushing air. Temperature affects air pressure. When air is heated, air molecules move faster. They push against each other and expand. The molecules become more spread out and the air in that space weighs less, so it exerts less pressure on the earth. This is called a low in weather terms. Cold air molecules are packed together. The cold air weighs more and exerts more pressure on the earth. In weather terms, this is known as a high.

These highs and lows greatly affect weather conditions. Low-pressure areas are created by warm air and generally indicate cloudy or stormy weather. High-pressure areas are created by cold air and indicate fair weather. Air moves from areas of high pressure to areas of low pressure. The movement of large air masses of different temperatures across regions of land plays a major role in the weather. An instrument called a barometer measures air pressure.

Co. glue stick/Water1 metric ruler 1 plastic soda bottle with a screw-on lidmasking tape

Procedures:EXPLORE (Part 1) Teacher Demonstration

1. Place the ruler on the table so that approximately 1/3 of the ruler extends over the table’s edge.

2. Cover the ruler with two full sheets of newspaper. Smooth the newspaper out from the center of the paper to the edges so there is as little air as possible between the paper and the table.

3. Put on a pair of safety goggles.4. Ask students to predict what will happen when you use a hammer to

strike the ruler quickly and as hard as possible. 5. Strike the ruler quickly and as hard as possible! (Note: Practice ahead of

time. This may take more than one attempt.)

EXPLAIN (Part 1)What happened when you hit the ruler quickly and as hard as possible? (The newspaper stayed in place. The ruler may have broken.)Why do you think the newspaper remained on the table? (The pressure of the air pushing down over the large surface of the newspaper pushes down and keeps the paper in place.)EXPLORE (Part 2)

1. Have students fill a plastic cup about ¾ full of water and wet the rim.2. Next, instruct students to lay the square of cardboard on top of the cup.

Hold the cardboard tightly against the cup, making sure no air bubbles enter the cup.

3. One student should turn the cup upside down over the bucket.4. The student should gently move his hand away from the cardboard.

EXPLAIN (Part 2)Why did the water stay in the cup? (The water should stay inside the cup because the pressure of the water against the cardboard is less than the pressure of the outside air against the cardboard.)

EXPLORE and EXPLAIN (Part 3)1. Have students place a piece of masking tape over the hole in the plastic

soda bottle.2. They should then fill the bottle two-thirds full with water and screw the lid

on tightly. 3. Ask the students to predict what will happen when they remove the tape. 4. Instruct students to hold the bottle over the bucket and then remove the

tape. 5. Ask: What happened? Why do you think so? (The pressure of the air held

in the water. A little water will come out at first, but then it will stop. The level of the water drops a fraction, and the air trapped between the top of the water and the closed bottle top has to expand to fill the space. Air pressure on top of the water decreases.)

6. Ask students to predict what will happen when they remove the lid. 7. Make sure students hold the bottle over the bucket before they remove

the lid.8. Ask: What happened? Why do you think so? (The water squirted out of the

hole because the pressure on the top of the water and the pressure on the water at the hole in the bottom of the bottle were equal. Then the weight of the water pushed the water out of the hole.)

EXTEND/APPLY 1. Read Making a Weather Station by Natalie Lunis.2. Refer students to a picture of a barometer or show them an actual

barometer. Explain to the students that a barometer measures air pressure in millibars. Explain that milli- means one-thousandth and bar is a Greek work that means heavy. This is the metric unit of pressure. Pressure causes the needle to move. Higher or greater pressure usually indicates fair weather, and lower pressure usually indicates stormy or cool weather.

3. Students can construct a barometer using a straw, an index card, a can with a lid or a jar, a balloon, and a rubber band. Construct the barometer when the air pressure for the area is normal. (Note: A coffee can with a snap-on lid may be used instead of the jar, balloon, and rubber band. If using a coffee can, have students skip to the fourth step.)

Cut a piece of the balloon to fit over the top of the mouth of the jar or can.

Stretch the balloon piece tightly over the mouth of the jar. Fasten the balloon piece to the jar with a rubber band. (Make sure

there is a tight seal.) Cut the straw so that one end forms a sharp point. Glue the drinking straw horizontally across the top from the middle

to the edge of the balloon. Mark off a 10-centimeter scale on the index card. (Note: This scale

is only for the purpose of making daily comparisons.) Mount the index card on a wall in an area where the temperature

does not vary a great deal. Set the barometer next to the index

card with the sharp edge of the straw pointing to the 5-centimeter mark.

3. Ask students to predict what will happen to the balloon when pressure on it increases or decreases. (When pressure increases, it pushes down on the lid, causing a high reading.)

4. Instruct students to take regular readings about the same time each day, observing changes in the balloon and noting the barometer scale number and the kind of weather occurring.

EXTENSIONSStudents can view daily weather reports, record the barometer readings, and investigate weather changes in connection with barometer readings. They can also record temperature readings and investigate the relationships between weather, temperature, and barometric pressure.

Title: The Heat Is On (Teacher)Benchmarks : SC.5.P.9.1 -Investigate and describe that many physical and chemical changes are affected by temperature.Essential Question: How does heat affect the properties of solids?

BACKGROUND INFORMATIONHeat is the name given to the energy that is transferred from one object to another by virtue of a difference in their temperatures. Whenever two samples of matter having different temperatures come into contact, energy is transferred from the one of higher temperature to the one of lower temperature until both have the same temperature.

The flow of heat through a substance from areas of higher temperature to areas of lower temperature is called conduction. Conduction can be explained by the kinetic energy of atoms within the material. Heat causes the atoms to vibrate more rapidly. These atoms vibrate against nearby atoms, which do the same until the kinetic energy moves throughout the object. The faster the atoms vibrate, the warmer the object becomes.

Metals, such as silver and copper, are best among common metals in conducting heat. A list of common substances in the order of their ability to conduct heat is shown. They are listed from the first, being the most efficient conductor of heat, to the last, being the least efficient conductor of heat: copper, gold, iron, glass, brick, water, nylon, wood (oak), concrete, wool, air.

Procedure:Safety Precaution: Students should wear safety goggles for this experiment. 1. Fold one piece of foil in half four times. Bend the ends of the foil down about 2 centimeters and

hook the ends over the tops of the two cans to create a bridge.

2. Place five chocolate chips along the foil bridge and wrap foil around the candle to create a cylinder.

3. Place the candle in the center under the bridge.4. Number the chips on the diagram to show the predicted melting pattern.5. Teacher will light the candle while students record the starting time. 6. Observe the chips as they melt, paying attention to the order in which they melt and how their

physical properties change Continue to observe the chips until the last one is melted. (You may need to use a toothpick to gently touch the chips to check for melting.)

7. Record the ending time on the activity sheet while the teacher safely extinguishes the candle.8. Discard the used foil bridge.9. Repeat steps 1-5, Teacher will now place the candle to the far left under the bridge.10. Continue with steps 7-9.

Title: How Does Sound Travel through Different Materials? (Teacher)Benchmarks : SC.5.P.10.1 Investigate and describe some basic forms of energy, including light, heat, sound, electrical, chemical, and mechanical. Problem Statement ( 10 POINTS) : How does_________________________________________________________ affect__________________________________________________________?Answer: How does a solid, liquid or gas affect how sound travels?Background Information:

Sound waves require some kind of material to travel through. They can't move through a vacuum.

Sound waves move much slower. Their speed in air is about 330 meters per second. Sound waves are like heat conduction. No particles actually travel. How Sound is Made:

When something vibrates, it moves back and forth. A vibrating object could be a speaker on a CD player, or your vocal cords, or the string on a guitar. As the object vibrates, it pushes the air molecules next to it closer together, in patterns corresponding to the movements of the object. These patterns of compressed air molecules bump into the ones next to them, passing on the pattern. In this way the original pattern of vibrations is sent through the air, as molecules continue to bump into their neighbors. Your eardrum is vibrating with the same frequency as the original sound. This vibration pattern is sent into the middle ear, where it is passed on by three small bones called the malleus, incus, and stapes. (You may be more familiar with them as the 'hammer', 'anvil', and 'stirrup'). You can see an actual photo of themHelpful Web site: http://www.worsleyschool.net/science/files/aboutsound/page.html

I FINALLY SEE THE LIGHT(Teacher Reference Page)

BENCHMARKS and TASKSC.5.P.10.1 Investigate and describe some basic forms of energy, including light, heat, sound, electrical, chemical, and mechanical. Also assesses SC.3.P.10.1, SC.3.P.10.3, SC.3.P.10.4, SC.3.P.11.1, SC.3.P.11.2, SC.4.P.10.1, and SC.4.P.10.3

KEY QUESTIONWhat forms of energy are able to light a bulb?

BACKGROUND INFORMATIONA battery has a positively charged terminal and a negatively charged terminal. In a closed circuit, electric charges are repelled by one terminal and attracted to the other

terminal. This attraction and repulsion provides the push that keeps the electric charges moving.In order for current to flow through a bulb, the bulb must be connected to the circuit at two points, the tip contact (the metal button at the bottom of the bulb) and the base contact (the metal side of the bulb’s base). Students will discover this through exploration with the materials. To make the bulb light with the materials in the following activity, either the base contact or the tip contact of the bulb must touch one terminal of the D-cell. The paper clip or wire must connect the cell’s other terminal to the remaining contact. (One way to do this is shown in the illustration below. Students will discover other ways.)

A light bulb contains a wire called a filament. When current passes through the filament, electric energy is converted into thermal energy. Eventually, the filament gets so hot that it starts to glow, giving off light.

MATERIALSTeacherThe Way Things Work by David Macaulay

Per pair of students (Part 1) (Part 2)bag containing: additional wire 1 D-cell Will I See the Light? activity sheet1 flashlight bulb 10-15 cm wireI Finally See the Light activity sheet wire strippers (if needed)

TEACHING TIPS1. Test bulbs and cells beforehand to be sure they are working.

2. Part 1: The D-cells, bulbs and wire should be placed in baggies ahead of time. Each pair receives one bag.

3. Although D-cells work best for this activity, C- or AA-cells can also be used.4. About 2-3 cm of insulation should be stripped from the ends of the wires so that a

good connection can be made. (A good substitute for wire is narrow strips of aluminum foil backed with masking tape and folded in half lengthwise with the masking tape on the inside.)

5. Part 2: Reserve the additional wire to distribute during this part.

ENGAGE1. Using David Macaulay’s book, The Way Things Work, examine the components of a

light bulb and discuss how they work.2. Show students a cross section of a light bulb. Have students sketch the bulb and

label the parts.3. Show students a flashlight bulb. Ask: How can I light this bulb? Record students’

responses.

EXPLORE (Part 1)1. Distribute a plastic bag of materials and the I Finally See the Light activity sheet to

each pair of students. Challenge students to light the bulb using only the materials in the bag.

2. After students have succeeded at lighting the bulb, encourage them to continue their exploration using the same materials to discover other ways to light the bulb.

3. Have students record their results on the I Finally See the Light activity sheet.

EXPLAIN Part 1)1. Ask:

What were some ways you were able to light the bulb? (Choose different student pairs to draw their ideas on the board.)How many different ways were you able to light the bulb with these materials? (Direct students’ attention to the drawings on the board and count the number of different ways to light the bulb.)When examining the different ways in which you were able to light the bulb, what were the similarities among the systems that worked?

2. Discuss the concept that in order for the bulb to light, either the base contact or the tip of the bulb must touch one terminal of the D-cell. The wire must connect the cell’s other terminal to the remaining contact, which is on the side of the bulb.

3. Introduce the term complete circuit. Explain that any system that caused the bulb to light is a complete circuit.

EXPLORE (Part 2)1. Distribute Will I See the Light? activity sheets and the extra wire to each pair of

students.2. Have students predict which of the pictured systems will light. Students should write

yes or no in the prediction box provided.3. Instruct students to build each system pictured and observe whether or not it lights

the bulb. Students should record yes or no in the actual box. (Note: Systems 1, 2, 3, 6 and 8 show complete circuits.)

4. When groups have finished testing all the systems, have them compare their predictions to the actual results.

EXPLAIN (Part 2) Which systems did not light the bulb? (4, 5, 7)Why did these systems not work? (They were not complete circuits.)

EXTEND/APPLYShow students some burned-out light bulbs. Try to determine where the complete circuit was broken. It is usually the filament. (Note: Students should not handle broken bulbs.)

EXTENSIONHave students use a battery (two or more cells linked together) as a part of the circuit and notice any difference in the brightness of the bulb. (Note: Don’t let students use more than two cells or bulbs may be burned out quickly.)

Analysis (30 points): Explain, in your own words, what you have learned and what the data means.

Problem Statement ( 10 POINTS) :

How can does electricity cause heat, light, sound, and motion?

TEACHER BACKGROUND INFORMATION All matter is made up of tiny particles called atoms. Each atom contains 3 basic parts:

Protons, which have a positive electric charge (+)Electrons, which have a negative electric charge (-)Neutrons, which have no electric charge

Protons and neutrons are in the nucleus or core of an atom, while the electrons orbit around the nucleus (see drawing #1). Most objects, such as balloons, have about the same number of electrons and protons, making them electrically balanced (see drawing #2).

Friction (rubbing two objects together) causes objects to gain or lose electrons. When this occurs, the object becomes electrically charged. This is called static electricity. If an object gains electrons when it is rubbed, it becomes negatively charged, because it has more electrons (-) than protons (+). If an object loses electrons when it is rubbed, it becomes positively charged because it has more protons (+) than electrons (-).(Note: Atomic structure is very abstract for students. It is enough for them to understand that an electric charge is created. Since there is no way for them to tell whether the charge is negative or positive, simply recognizing that the object has a charge is enough.)

A basic principle of electric charges is that like charges repel and unlike charges attract.When a balloon is rubbed on you hair, it gains electrons from your hair and becomes negatively charged. Your hair becomes positively charged and will stick up because like charges repel. When the negatively charged balloon is brought near your hair, it will be attracted because unlike charges attract.

When a negatively charged balloon is brought near a wall, it induces a positive charge near the surface of the wall. (The electrons on the balloon repel electrons near the

surface of the wall.) Since opposite charges attract, the balloon clings to the wall (see drawing #3).

BACKGROUND INFORMATIONThis lesson is a great opportunity for students to observe and apply some of Isaac Newton’s Laws of Motion. Newton was an excellent observer of everyday occurrences. Newton’s First Law of Motion states that objects at rest tend to stay at rest until a force acts on them. An object’s tendency to resist a change in motion is called inertia.

A sphere is an object that has mass. When the sphere is held at the top of the ramp in this lesson, it is not moving, but it does have stored energy, called gravitational potential energy, due to its position. It will stay there with its potential energy until some force acts upon it. When the sphere is released, the force of gravity (a pulling force) takes over and the sphere rolls downward, releasing its stored energy. The energy is changed into kinetic energy, energy of motion. This kinetic energy is then transferred to the slider, which causes it to move. The heavier and larger the sphere is, the more potential energy it would have, the faster it would travel, and the farther the slider would move. This lesson provides an opportunity for students to experience physics that is fun, not intimidating!

SAFETY: Always follow science safety guidelines.

TEACHING TIPS Have students tape their ramp to the table for stability. This lesson will likely require more than one class period. All groups should have equal size and mass spheres and all other materials

should be as similar as possible to ensure control of the experiment.

Procedure:ENGAGE

1. Have the ramp and slider set up in place on a smooth surface where everybody can see it.

2. Have students write the key question in their science notebook. Ask them to take a few moments and think-pair-share with a partner and to write their preliminary thoughts in their notebook.

3. Regroup and ask students to share their preliminary thinking. Use this opportunity to check for student understanding and misconceptions.

4. What are some forces acting on Earth? (push, pull, gravity, friction)5. What is a push? (moving something away)6. What is a pull? (bringing something closer)7. Knowing these two definitions, is gravity a push or a pull? How do you know?

(pull, because it is bringing things closer to Earth)8. What is friction? (when a push and pull meet, creates sound and heat energy, it

is a force that slows things down)

EXPLORE 1. Distribute the materials. Before starting the experiment, establish these

guidelines: All experiments should take place in the area that you designate for each

group. Make sure the sliders are placed even with the end of the ramp for each

trial. The spheres should be released down the ramp – not pushed. Re-check the set up before starting each trial.

(Note: If you are using rulers, marbles, and cups instead of commercial ramps and sliders, have students set the 4 cm mark of the ruler on a textbook to form a ramp. Designate markings on the ruler at which students should release the marbles.)

2. Students should take turns releasing the sphere three times from level 5. 3. Each time students should record the distance the slider travels by measuring in

centimeters from the end of the ramp to the leading edge of the slider. These recorded data charts should be copied into the student science notebooks by students.

4. Each test should be repeated for a minimum of three trials with results averaged.5. Students should repeat steps 3 – 5 with the various surfaces under the slider.


EXPLAIN In what situations did the slider travel farther? Why? (An object’s acceleration

depends on the size and direction of the force acting on it. There is a difference in the amount of friction depending on the surface on which the slider was placed. )

What forces were acting on the sphere? (the force of gravity pulling it toward the Earth, the force of friction as it rolled down the ramp)

What forces were acting on the slider? (the force of the sphere connecting with the slider, the force of friction from the surface that the slider was on, the force of gravity pulling the slider toward the Earth)

As the sphere rolled down the ramp, according to Newton’s law, the sphere had inertia and should keep rolling along unless acted on by an outside force. What force caused the sphere to suddenly stop? (the force of friction from the surface and the slider)

Why did we all release the sphere from the same level? (to ensure that our experiment was controlled and that only one variable was changed- surface type)

Why did we all use the same size and shape sphere? (to ensure that our experiment was controlled and that only one variable was changed- surface type)

Why did we repeat the experiment? (to ensure more accurate results) How is this experiment different from other investigations we have done? (we

controlled our variables)

SAFETY: Always follow science safety guidelines. TEACHING TIPS

Have students tape their ramp to the table for stability. This lesson will likely require more than one class period. If possible, find more than two spheres of difference masses. The spheres should

preferably be the same size- for example, a large marble versus a similar size metal sphere.

Procedure:ENGAGE

1. Have the ramp and slider set up in place on a smooth surface where everybody can see it. Remind students of the previous activity (Ramps and Sliders: Friction, Ramps and Sliders: Gravity) and ask them what they learned from that activity. Listen to responses and reiterate the fact that the higher the ramp, the more gravitational potential energy and, therefore, the more energy provides the ability for the sphere to travel farther.

2. Have students write the first key question in their science notebook. Ask them to take a few moments and think-pair-share with a partner and to write their preliminary thoughts in their notebook.

3. Regroup and ask students to share their preliminary thinking. Use this opportunity to check for student understanding.

4. Tell students that they are going to use the ramps, sliders, and spheres to design an experiment to answer the key question. Ask students: Using the materials provided, what is a testable question we can ask to find the answer to our key question? Provide students time to think-pair-share. Have students report out and list the questions on the board or on chart paper.

5. Lead a discussion by asking students to discuss the questions listed on the board or chart paper. Focus on which are testable questions and which are not. Remember that testable questions are used to create experiments that can be tested.

6. Have students decide on a testable question as a class that connects with our overriding key question. The question should be something like: What is the difference in the distance spheres of different masses travel?

EXPLORE 1. Distribute the materials. Before starting the experiment, establish these

guidelines: All experiments should take place in the area that you designate for each

group. Make sure the sliders are placed even with the end of the ramp for each

trial. The spheres should be released down the ramp – not pushed. Re-check the set up before starting each trial.

(Note: If you are using rulers, marbles, and cups instead of commercial ramps and sliders, have students set the 4 cm mark of the ruler on a textbook to form a ramp. Designate markings on the ruler at which students should release the marbles.)

2. Students should take turns releasing the small sphere three times from levels 1, 3, 4, and 6 on the ramp. STUDENTS ARE NOT TO TEST AT LEVELS 2 AND 5 AT THIS TIME.

3. Each time students should record the distance the slider travels by measuring in centimeters from the end of the ramp to the leading edge of the slider. These recorded data charts should be copied into the student science notebooks by students.

4. Each test should be repeated for a minimum of three trials with results averaged.5. Have students create a bar graph of their data in their science notebook. 6. Collect one group’s data and create a bar graph on a transparency or project

using the document camera. Display the graph for the class. Discuss the results with the class and ask if they can see any pattern in the data.

7. Using this information, ask students if they can now predict how far a slider would travel when the same sphere is released at levels 2 and 5 on the ramp.

8. Discuss the small range of responses. Ask: How did the data collected help you predict? Explain that now students have data on which to base their predictions, so they are not just making wild guesses.

9. Have all groups perform tests at levels 2 and 5 to verify the accuracy of their predictions.


EXPLAIN Why was the range of responses for the guesses so large? (No data was

available to give the students a reasonable range of results.) Why was the range of responses for the predictions so small? (The data revealed

a pattern that made it easier to determine what the actual result would be.) What information do you need in order to make accurate predictions? (reliable

data) What sphere position made the slider travel farther? Why? (An object’s

acceleration depends on the size and direction of the force acting on it. There is

a difference in the amount of gravitational potential energy depending on the height at which the sphere is released)

From where did the energy come to move the sphere and the slider? (The sphere is sitting at rest at a level on the ramp; it is not moving, but it has stored energy, called gravitational potential energy due to its position. When the sphere was released, potential energy was converted to kinetic energy. When the sphere hit the slider, energy was transferred from the sphere to the slider and the slider moved.)

As the sphere rolled down the ramp, according to Newton’s law, the sphere had inertia and should keep rolling along unless acted on by an outside force. What force caused the sphere to suddenly stop? (the force of friction from the table and the slider)

Why did we repeat the experiment? (to ensure more accurate results) How did you predict the slider’s travel distance for levels 2 and 5? Were your predictions correct? Explain why or why not.

Data (20 POINTS):

2. Have students repeat the investigation. Students should compare their results and discuss similarities and differences in results and the reasons for these.

3. Have students repeat the investigation using stopwatches to time the spheres as they move. Students can then determine the speed of the spheres by dividing the distance traveled by the time it took.

BENCHMARKS AND TASKSSC.5.L.14.1 Identify the organs in the human body and describe their functions, including the skin, brain, heart, lungs, stomach, liver, intestines, pancreas, muscles and skeleton, reproductive organs, kidneys, bladder, and sensory organs.

SC.5.L.14.2 Compare and contrast the function of organs and other physical structures of plants and animals, including humans, for example: some animals have skeletons for support — some with internal skeletons others with exoskeletons — while some plants have stems for support. Also assesses SC.3.L.15.1 and SC.3.L.15.2

KEY QUESTIONWhat is your vital lung capacity?

BACKGROUND INFORMATIONAll animals need oxygen to live. Land animals get oxygen when their lungs pump in air. When air is inhaled, the diaphragm contracts and drops down to enlarge the chest cavity. At the same time, rib muscles contract and lift the ribs upward and outward. Air rushes in to fill the space. When air is exhaled, the diaphragm relaxes back into its up position, and the ribs settle down. The space shrinks and air is squeezed out of the lungs. Different people have different lung capacities and different breathing rates; what’s natural for one person may not be for another. (Note regarding this activity: A person cannot exhale all the air that is in the lungs. The amount that can be exhaled is the vital capacity, although sometimes it is incorrectly called the lung volume. The lung volume is actually all of the air that can be held inside the lungs.)

The lungs are about the size of a pair of footballs, and they fill the chest from neck to ribs. Air passes in through the windpipe, which divides into two branches, called the bronchial tubes. These divide into smaller tubes called bronchioles. These open into little air sacs called alveoli. You have about 600 million of these spongy sacs. Our breathing system allows us to take in air, remove oxygen from it, and exhale a body waste product called carbon dioxide. One’s rate of breathing is controlled automatically in the brain.

1 measuring cup or graduated cylinder 1 index card1 permanent markerpaper towels1 bag for used strawsnewspaperseveral metric measuring tapes

TEACHING TIPS1. Be sure that each student uses a clean straw!2. Be sensitive to individual student data. The purpose of the investigation is to show that

there are differences in lung capacity due to many factors.3. Note that there may be some students who can push all of the water out of the gallon

jug!4. This activity is easier to manage if student groups work near a sink area. You may

choose to give each group a set of materials, or you may choose to set up only one station near a sink area where each group can take a turn.

5. Before the lesson, have students work with partners to determine their height in centimeters.

ENGAGE1. Ask students to sit still and count the number of times they breathe out in one minute.2. Have students compare their breaths per minute to other students’ rates. (Note: A line

plot would be useful here.) 3. Ask: Is everyone’s breathing rate the same? Why do you think they’re different?4. Tell students to bend and touch their toes 50 times and then count their breaths for one

minute. 5. Ask: How does exercise affect your breathing rate?

EXPLORE1. Instruct groups to cover their table with newspaper. Distribute the other materials to

each group.2. Have each group fill a large basin half full (approximately 6 inches) of water.3. Students should tape a bag to the table for the disposal of used straws.4. Show students how to calibrate the jug:

Have students use a measuring cup or graduated cylinder to add 400 mL of water at a time to the jug. Using a permanent marker, students should mark the water level along the side of the jug after each addition.

Students should continue adding water and marking until the jug is completely filled. (The last addition of water will probably be just a portion of the 400 mL.)

Write the calibrations on the jug, starting at the top, with the jug turned upside down.

Have students completely fill the jug with water (if it was emptied to write on) and screw on the lid.

5. Students will need to put two straws together by inserting one part of the way into the other to make them long enough.

6. Tell students to tip the jug upside down in the basin so the bottleneck is underwater. Remove the lid.

7. The first student should put one end of the lengthened, flexible straw inside the bottleneck. The student should take a deep breath and exhale as slowly and completely as possible into the straw. Tell students not to exhale too quickly or some of the air will bubble out the sides instead of going up inside the jug.

8. Quickly put the lid back on the jug.9. Observe the level of the water to determine how much water has been pushed out of

the jug by the air that was breathed into it. Record.10. Students should continue the process until each person has had a chance to determine

his/her vital lung capacity. Remember to refill the jug with water each time.

EXPLAIN1. Discuss:

What pushed water out of the jug? (air that was exhaled into the jug)What would be equal to the amount of air you breathed into the jug? (The volume of air in the jug is approximately the same as the volume of air that was exhaled.)

2. Have students write their height in centimeters on one side of an index card and their vital lung capacity in milliliters on the other side of the card. Have students stand up and order themselves according to their vital lung capacity. Use the class data to discuss these questions:

What is the class range of vital lung capacities? What is the most frequent vital lung capacity measurement (the mode)?What is the median? What is the average vital lung capacity of the class (the mean)?

Next, have students stand up and order themselves according to their height. Discuss: Are we in the same order for height as we were for vital lung capacity?

Does the tallest person also have the greatest vital lung capacity?

EXTEND/APPLYDiscuss the flow of air through the lungs as students label the picture on the student worksheet.

EXTENSIONS1. It is a fact that continuous exposure to polluted air or cigarette smoke over a long

period of time damages the lungs. One result of this damage is that the lungs slowly lose their ability to absorb oxygen from the air and eliminate carbon dioxide. Contact the American Lung Association for educational materials or request speakers on this topic.

2. Students can investigate exercise and age as factors that influence lung capacity (e.g., How can people keep maximum lung capacity as they age?).

THE HUMAN LUNGS

THE BEAT GOES ON(Teacher Page)



KEY QUESTIONWhat causes a change in pulse rate?

BACKGROUND INFORMATIONDuring an average lifetime, your heart, an organ the size of your fist, will beat almost 3 billion times. The heart is the strongest muscle in the human body. The heart is located in the center of the chest between the lungs and just under the breastbone.

The heart has four chambers through which blood passes. Both sides of the heart are divided into two chambers. The upper chamber is called the atrium, and the lower chamber is called the ventricle. Blood passes through the right atrium and the right ventricle and then to the lungs, where it picks up oxygen. This oxygen-rich blood is then pumped through the left atrium and the left ventricle and out to the body through the aorta.

right ventricle

When the heart contracts (pumps), it forces blood out into the arteries (tubes that carry blood from the heart to all parts of the body) and the walls of the arteries stretch. As the heart relaxes, the artery walls contract elastically to push the blood along. Each time the heart beats, the artery walls expand and contract once to produce one beat.

You can listen to a heartbeat, but you can feel your pulse. The pulse is caused by blood stopping and starting as it rushes through the arteries. By counting these pulse beats, you can tell how fast

right atrium left atrium

left ventricle

aorta to the body

pulmonary artery to the lungs

your heart beats. A general guide for the pulse rate is: 50-100 beats per minute resting, 90-150 beats per minute after walking, and 160-220 beats per minutes after running. Children’s heartbeats are normally faster than adults’ heartbeats. A person’s resting pulse rate decreases with age.

MATERIALSPer student Per classmodeling clay clock/watch with a second hand 1 wooden match or toothpick model of the human heart1 calculatorThe Human Heart worksheet Per group

1 tennis ball

TEACHING TIPSShow students how to use their fingers to locate their pulse:

1. Begin by putting the tips of the index and middle fingers together side by side on the right hand.

2. Turn the left hand facing you with the palm up.3. With the two right hand fingertips, trace a path on the left hand beginning at the left thumb

all the way up to a point approximately 3.5 cm up the arm from where the wrist begins.4. Keep the fingertips in an arched position for increased sensitivity. You should now be able

to feel a pulse.5. Do NOT use your thumb to take a pulse as thumbs have their own pulse!

ENGAGEHave students take turns squeezing a tennis ball to simulate the force needed to squeeze blood out of the heart. If they squeeze 60 times a minute, they will have a good idea of how hard the heart works. The normal resting pulse rate is 50-100 times per minute.

EXPLORE1. Tell students we can feel our own pulse beat by placing our fingers on a spot where there is

an artery close to the surface of the skin. Explain that some arteries are too deep in the body to feel a good pulse beat. Another place to find a pulse is on the side of your throat, just under your chin. This artery is called the carotid artery. Ask students if they can find a pulse any place else on their bodies - face, armpit, elbow, wrist, abdomen, hip joint, knee, or ankle.

2. While students are seated, ask them to count the number of pulse beats in 15 seconds. Have students multiply this number by four to get their resting pulse rate per minute. Have students record this measurement.

3. Have students take a pulse rate again to see if they get the same results. 4. Ask students to walk briskly for one minute and then find their pulse rate again immediately

afterwards. Be sure they record the results on their data sheets.5. Have students run in place for one minute and repeat the procedure.6. Have students relax and let their pulse rates return to the resting rate. Have them note how

long this takes on the data sheet.

EXPLAIN1. Discuss:

Did all students have the same resting pulse rate? Why?

Did all students have the same pulse rate after exercising? Why?What was the class range of pulse rates for each activity?What was the difference in your pulse rates after one minute of brisk walking?What was the difference in your pulse rates after one minute of running in place?How long did it take for your pulse to return to its resting rate?

2. Average the students’ individual rates to get the average pulse rate for the class - a great calculator activity. Ask: What was the average resting pulse rate for the class?

EXTENDAPPLY1. One way for students to visualize a heart beat is to make a pulse meter.

Form a small ball of clay about the size of a dime. Stick a toothpick or wooden matchstick in the clay so that it is facing upwards like a

pointer. You may want to color the tip a dark color with a marker so you will be able to see the

movement of the pointer better. Place this pulse meter on the pulse spot on your wrist. You may have to move it around

to find the best spot. Try the inside of your left wrist on the thumb side. You should now be able to see the pulse meter moving in time with your pulse rate.

2. Use a model of the human heart to help students label the heart on the student worksheet and explain the flow of blood.

EXTENSIONObtain a stethoscope and have students listen to someone’s heart beat.

THE HUMAN HEART

THE BODY’S FILTERING SYSTEM(Teacher Page)

BENCMARKS AND TASKSSC.5.L.14.1 Identify the organs in the human body and describe their functions, including the skin, brain, heart, lungs, stomach, liver, intestines, pancreas, muscles and skeleton, reproductive organs, kidneys, bladder, and sensory organs.


KEY QUESTIONHow are waste products removed from the blood in the kidneys?

BACKGROUND INFORMATIONThe job of the excretory system is to remove wastes produced by the activities of cells. Many of these wastes are eliminated as liquid urine. Urine is formed by the urinary system, which is made up of the kidneys, the ureters, the urinary bladder, and the urethra.

Kidneys are filters that are located near your spine in the middle of your back. The kidneys perform two jobs. They retain non-waste materials (e.g., proteins, sugar) to be reabsorbed into the blood stream through the circulatory system, and they rid the body of wastes. These waste products are eliminated from the body in the form of urine. This separation is accomplished through a process called filtration. Each kidney is a mass of more than a million filter tubes, called nephrons, where blood is filtered in and then out again. In one minute, more than one quart of blood will make its way through the kidneys. The blood enters the kidney through a large artery and flows into ever-smaller blood vessels. Waste products are collected in these tubes and drain from each kidney to the bladder in the form of urine through tubes called ureters. The bladder is a muscular bag located in the middle of your lower abdomen. The urine enters and is stored in the bladder and exits the body through a single tube called the urethra.

The roles of the excretory system and the digestive system are different in eliminating wastes from the body. Feces are the unusable remains of food you eat. Urine is cellular waste that has been filtered from your bloodstream.

KIDNEY

ENGAGEDiscuss how the body must separate waste products from useful products. Relate to things students have seen filtered in daily life (e.g., coffee, water). Display a coffee filter and coffee pot. Discuss why the coffee filter is necessary because it separates the waste – the used coffee grounds – from the coffee.

EXPLOREPart 1

1. Use the model of the human body to point out the main parts of the urinary system.2. Have students draw and label a diagram of the kidneys and bladder. Discuss the function of

each part. Clarify and discuss the following terms: kidney, bladder, urethra, ureter.Part 2 Tell students that they will be demonstrating how the kidneys work as a filtration system for the body. Provide the following directions for each group, along with 2 plastic cups, water, food coloring, coffee filter, spoon, paper towel, and chalk.

1. Pour enough water to fill one cup half full.2. Add a few drops of food coloring.3. Crush the chalk on a paper towel.4. Add ½ spoonful of crushed chalk to the colored water.5. Place the coffee filter over the top of the second cup and secure with a rubber band, if

needed. 6. Slowly pour the colored water mixture onto the filter.7. Observe the contents of the coffee filter and the cup.

EXPLAINWhat happened in this investigation that is similar to what happens to blood in the kidneys? (The filter separated the waste products from non-waste products.)Where is the waste product and where is the non-waste product? (The waste product, urine, is in the filter. The non-waste is in the bottom container.)If the colored water in the bottom container represents the non-waste product found in the urinary system, what will happen to it in the body? (It will be reabsorbed into the body through the circulatory system.)If what remains in the coffee filter represents the waste product known as urine, what will happen to it in the body? (The urine will pass from the kidneys into the bladder through the ureters. The urine will be stored in the bladder until it is released, and it will then exit the body through the urethra.)

EXTEND/APPLYDiscuss ways to keep the kidneys in good working order. (e.g., Stress the importance of drinking water every day to flush out the body’s excretory system.)** How does the solid waste get removed from the body?

ASSESSMENTHave students answer the key question: How are waste products removed from the blood in the kidneys.

MUSCLE MATES(Teacher Page)

** Activity may take up two class periods.



KEY QUESTIONHow do the muscles in your body help your limbs to bend, reach, twist, lift, flip, leap, and even move the muscles in your hand so you can grasp a pencil to do your homework?

BACKGROUND INFORMATIONBones form your body’s framework, but they can’t move by themselves; they need extra help. Every time a bone moves, there is a muscle to move it. There are more than 600 muscles and more than 200 bones in the human body. Every moving bone has at least two muscles attached to it. Muscles work in teams because they can move in only one direction; they only pull (contract). One muscle contracts and pulls a bone to get you into a certain position. Then its partner must contract to pull the bone back and get you out of the position. A muscle can perform just one single motion. A muscle can make itself shorter by contracting. When it’s not doing that, it relaxes. Tendons are the ties that bind muscles to your bones. The joints of the bones are connected by strong, fibrous tissue called ligaments.

A muscle receives an electric command from the brain through the nerves. The neurons (nerve cells) get their instructions from the brain on which muscle to move and then the electric stimulus to that muscle stimulates the muscle movement or “reflex” action.

There are three types of muscles. Skeletal muscles are the muscles that move your bones and other parts of your body, such as your eyes. They are voluntary muscles that operate on command from your brain. Smooth muscles work automatically. They are involuntary muscles, such as the muscles that control the movement of food in our stomach. They are found in the internal organs like the stomach, heart, and lungs. Cardiac muscle is muscle found only in the heart.

MATERIALSPer class

1 meter stick 1 timer1 roll of heavy string 1 wide-mouth glass jar1 roll of masking tape 1 rubber band

Per group2 pieces of tag board 16 cm x 5 cm 1 brass fastenerscissors tape2 strips of elastic, each 15 cm long 1 hole punch

ENGAGE1. Explain that there are some “rules” that our muscles must follow in order to function

properly. They must only pull, they never push, and they always work in pairs. Set the scene by telling the class, Look what happens when you bend your arm. To feel these muscles at work, straighten your right arm. Now put your left hand on your right upper arm and slowly bend your right arm. You will feel the biceps muscle contract, getting thicker as it does so.

2. Tell the class: Today you are going to take part in a Muscle Tug-o-War. You will play the roles of muscles and brain neurons. Do I have any volunteers?

EXPLORE (Part 1)1. Cut a piece of string about 12 meters long.2. Lay the string out on the floor and place the meter stick representing the bone directly in the

center of the string in a vertical position. 3. Wrap about one meter of string around the top of the meter stick in one direction, and then

wrap another one-meter length of string around the top of the meter stick going in the opposite direction. You should end up with the meter stick in the middle of the string with 5 meters of string hanging loose on both sides of the meter stick. (Note: If the string starts to pull loose, you may want to place a rubber band around the part of the string wrapped around the meter stick.)

4. Place the jar on the floor in the middle of the room or out in the hallway.5. Ask for two student volunteers. Have one of the students line up approximately 5 meters

from one side of the glass jar.6. Have the other student line up the same distance on the opposite side of the jar so that he/she

is facing the other student.7. Tell each student to grasp an end of the yarn but caution them not to pull hard.8. Choose another student to be the timer of this event. 9. Say to the students: On the signal “go,” you will pull lightly on your yarn and see if you and

your partner can guide the meter stick into the jar. You can do this only by pulling and working together. Try to complete this task in the least amount of time possible.

10. Once students have completed the task and recorded their time on the board, let other student pairs play the role of muscles.

***EXPLAIN (Part 1) – Do as Demo whole class1. After everyone has had a chance to participate in the activity, discuss:

In human body terms, what did the string represent? (Tendons) What did the meter stick represent? (Bone) What did the two students represent? (Muscles)What did getting the stick into the jar represent? (Doing work)To perform this task successfully what did each muscle pair need to do? (Work in pairs and only pull, not push.)

2. Discuss with the class how all of these body parts - tendons, bones, and muscles - work together to allow the body to function as a smooth-running machine. (See Background Information.)

EXPLORE (Part 2)1. Have each student place his/her left hand over the biceps (the large muscle on the front of

the upper arm) of the right arm while moving the right forearm up and down. Discuss how the biceps extends flat when the forearm is down. The same biceps seems to form a tight ball when the forearm is flexed upward toward the shoulder.

2. Ask: If the biceps is the muscle that makes the forearm go upward, how does the forearm go downward? Have students put the fingers of their right hand over the large triceps muscle at the back side of the upper arm. Now have them slowly move their forearms up and down with tension as if they were moving a heavy weight in their right hands. They should be able to feel some changes in the triceps muscle. It is needed to make the forearm go downward.

3. Have each group construct a model arm to help them understand how the bones and muscles work together. Begin by having students cut two pieces of tag board, each about 16 cm x 5 cm. Round the corners.

4. Punch one hole in the center of the end of each tag board piece and use a brass fastener to connect the two pieces, creating a joint.

5. Punch two holes in each piece of tag board near the long edges about 8 cm from the ends. 6. Cut two strips of elastic each about 15 cm long. Push the elastic strips through the holes;

each strip should go from a hole in one tag board piece to the hole in the other tag board piece.

7. Tie knots in the ends of the elastic strips or tape them to the tag board to secure them.

8. The tag board pieces represent the bones, and the elastic strips represent the muscles. The model arm has only two muscles while a real arm has many.

9. Watch what happens when you move the model arm. To pull the bones and make the arm bend, give a slight push. Then give a push in the opposite direction to make the arm straighten. For real muscles, the push is provided by the brain.

EXPLAIN (Part 2)What do the tag board pieces represent? (Bones)What do the elastic strips represent? (Muscles)Why does the model arm have at least two muscles? (Muscles work in teams, because they can move in only one direction; they only pull [contract]. One muscle contracts and pulls a bone to get you into a certain position. Then its partner must contract to pull the bone back and get you out of the position.)What do muscles do for us? (move bones)

EXTEND/APPLY1. Have a doctor/speaker from an orthopedic clinic make a presentation to the class. The

speaker can share x-rays so students can get a closer look at bones/muscles.2. Have students place one arm on the desk with the palm of the hand facing upward. Ask them

to see how many times they can make a fist in 30 seconds, each time opening the hand completely and then forming a tight fist. Repeat the test several times. Ask: Can you make the same number of fists each time? When does your arm begin to feel tired? (Your forearm muscles, which operate the fingers, are becoming fatigued. When a muscle becomes tired, fatigue occurs. The muscle may feel strained or it may not respond when you want it to.)

ASSESSMENTAsk students to write in their science journals a short explanation of how muscles and bones work together and have them include drawings and terminology in their writing.

DISCOVERIES ABOUT DIGESTION(Teacher Page)



KEY QUESTIONWhat path does food follow through the digestive tract?

BACKGROUND INFORMATIONThe digestive tract is the body’s passageway through which food moves and digests. The digestive tract includes the mouth, esophagus, stomach, small intestine, large intestine, and the anus. Other organs that support digestion are the salivary glands, pancreas, liver, and gall bladder.The digestive system physically and chemically breaks down food to supply the body with its energy and nutrient needs for growth and repair. The teeth physically break the food into smaller pieces. The tongue moves the food particles into a ball that is swallowed. The food moves down the throat into the esophagus, the food tube that is lined with muscles that help to mix the food and push it down toward the stomach. The stomach, which can hold two to four liters of food, kneads the food, breaking it down more. The stomach also adds chemicals to the food, turning it into a soupy liquid. The food then passes into the small intestine, a narrow tube and the longest part of the digestive tract. The food is then broken down into particles small enough to be absorbed into the bloodstream.The liver produces bile, which is stored by the gallbladder and then released into the small intestine where it helps to break down the fats. The liver stores the fats and carbohydrates we use for energy along with iron and other vitamins. It also regulates the blood sugar levels in the body. The pancreas produces chemicals that help in the digestion of carbohydrates, fats, and proteins. It also helps to neutralize the stomach acids. The digestive tract is a continuous muscular tube that runs from the mouth to the anus. An adult’s digestive tract is approximately nine meters (30 ft.) in length – about five times the adult’s height.

MATERIALSPer student or per group (See Teaching Tips)1 body cutout from craft paper construction papercash register tape or crepe paper scissorsglue calculator

TEACHING TIPS1. Give students a piece of craft paper or butcher paper and ask

them to have someone at home trace around their body. They should cut this out and bring it to school on the designated day.

2. As an alternative, one student per group could volunteer to create the body outline. Then students could work as a group to create one digestive tract model per group. This would require less space in the classroom.

ENGAGE1. Ask students to predict how long their digestive tract is from their mouth to their anus. They

should cut a piece of cash register tape this length and write their name on it.2. Next, have students use calculators to determine the actual length of their digestive tracts,

using the following measurements:Mouth to esophagus 10 cmEsophagus 25 cmStomach 15 cmSmall intestine student’s height x 3Large intestine to anus student’s height + 15 cm

3. Add these amounts to find the total length of the digestive tract.

EXPLORE 1. Have students trace around their bodies on craft paper or have them bring these cutouts from

home – as assigned earlier.2. Have students cut cash register tapes or crepe paper strips about 5-8 cm wide to the lengths

listed in the Engage section. 3. The strips can be rolled to form an actual tube. (For the large intestine, two strips can be

glued along the edges to form a larger tube.)4. Students should position the paper strips representing the digestive tract on their body

cutouts. Once the strips are in place, students will glue them to the body outline.5. Have students draw the remaining main organs (stomach, liver, pancreas, and gall bladder)

on construction paper and cut them out.6. They should position the organs on the model, glue them in place, and then label them.

Students should label the mouth, esophagus, stomach, liver, pancreas, gall bladder, small intestine, large intestine, and anus.

7. Each group should research the various organs included in the digestive system and be prepared to use the model to trace the path of food through the digestive tract.

EXPLAIN What is the function of the digestive system? (the physical and chemical breakdown of food to supply the body with energy and nutrients needed for growth and repair)Where does digestion begin? (the mouth)Where does digestion end? (Waste products pass from the large intestine through the anus and are expelled from the body.)What is the role of each organ in digestion? (See Background Information.)

What is the longest organ of the digestive tract? (the small intestine)Why do you think the small intestine is so long? (There the food is broken down into particles small enough to be absorbed into the bloodstream.)Approximately how long is the digestive tract in an adult? (about five times the adult’s height)

EXTEND/APPLYHave students determine the average ratio of their heights to the length of their digestive tracts.

ASSESSMENTHave students answer the key question: What path does food follow through the digestive tract?

anus - the opening at the end of the digestive system from which feces (waste) exits the body.appendix - a small sac located on the cecum.ascending colon - the part of the large intestine that run upwards; it is located after the cecum.cecum - the first part of the large intestine; the appendix is connected to the cecum.descending colon - the part of the large intestine that run downwards after the transverse colon and before the sigmoid colon.duodenum - the first part of the small intestine; it is C-shaped and runs from the stomach to the jejunum.esophagus - the long tube between the mouth and the stomach. It uses rhythmic muscle movements (called peristalsis) to force food from the throat into the stomach.gall bladder - a small, sac-like organ located by the duodenum. It stores and releases bile (a digestive chemical which is produced in the liver) into the small intestine.ileum - the last part of the small intestine before the large intestine begins.jejunum - the long, coiled mid-section of the small intestine; it is between the duodenum and the ileum.liver - a large organ located above and in front of the stomach. It filters toxins from the blood, and makes bile (which breaks down fats) and some blood proteins.mouth - the first part of the digestive system, where food enters the body. Chewing and salivary enzymes in the mouth are the beginning of the digestive process (breaking down the food).pancreas - an enzyme-producing gland located below the stomach and above the intestines. Enzymes from the pancreas help in the digestion of carbohydrates, fats and proteins in the small intestine.rectum - the lower part of the large intestine, where feces are stored before they are excreted.sigmoid colon - the part of the large intestine between the descending colon and the rectum.stomach - a sack-like, muscular organ that is attached to the esophagus. When food enters the stomach, it is churned in an acid bath.transverse colon - the part of the large intestine that runs horizontally across the abdomen.

KEY QUESTIONHow does hypertension affect the brain and the central nervous system?

BACKGROUND INFORMATIONThe nervous system is made up of the brain (the major command center), the spinal cord (the nerve highway), and the neurons (nerve cells). The basic job of the nervous system is to assist the body as it reacts to changes in the environment and adjust to any necessary changes. It does this by split-second reactions that transfer electrical impulses via neurons along the spinal cord and then transfer this energy to the muscles and internal organs. When the nervous system is working properly, it coordinates the normal work of your trillions of cells. It monitors your internal operations as well as what goes on in the world outside your body. It senses changes in the environment and makes the necessary adjustments. It keeps things running smoothly and on course. There are, however, times when things can go wrong with the nervous system.

Hypertension, or high blood pressure, is a serious problem that can damage many organs of the body, particularly the brain and the heart. Hypertension can cause the heart to enlarge and become weak. It can cause arteries to become scarred and less elastic. This can lead to the formation of blood clots that can cause heart attacks or possible strokes to the brain. The occurrence of cerebral hemorrhage or stroke reflects the severe stress that is imposed upon the large arteries. The blood that seeps out accumulates, presses upon the delicate brain tissue, and causes damage to brain cells. This damage can cause paralysis, disturbances in speech, sight, and other complex activities.

Tie the laces. Untie the laces and remove the shoe.

ENGAGEAsk for a student volunteer to come to the front of the class. Ask the student if he thinks he could complete a simple task in a very short period of time. Tell the student that you want him to completely screw on a nut to a bolt and then unscrew the nut from the bolt. He must complete this in less than 10 seconds, but the catch is…he cannot use either of his thumbs. He must use only his fingers. Begin timing the student. Once frustration has taken over, discuss why this task was so difficult. Tell students that they are simulating a “nerve” roadblock to completing the task, and they will be investigating several more nerve roadblocks.

EXPLORE1. Divide the class into groups of four. They will be taking turns at each station as recorders,

timers, investigators, and observers.2. Instruct students to perform the tasks at each station (see Teaching Tips) and time how long

it takes to perform these tasks. Record this data on the Brain Drain Olympics worksheet.3. Instruct students to perform the tasks a second time, but this time the student who is

KEY QUESTIONHow have bird beaks adapted to enable birds to eat the different food sources in their environment?

BACKGROUND INFORMATIONBirds’ beaks serve a wide variety of purposes. Birds use their beaks mainly to obtain food and drink water. Birds also use their beaks to build nests, attack intruders, groom feathers, scratch their bodies, and feed their young. Each type of bird has a special type of beak, an adaptation for eating a certain type of food. Their beaks are essential to their survival. Examples of birds and their beaks include:

Hummingbirds have long, hollow beaks that they use to probe flowers for nectar. The beak protects the tongue that slurps up the nectar.

Eagles have strong, hooked beaks that tear food. Curlews, godwits, kiwis, and snipes have very long beaks that they use to probe for worms,

crustaceans, and other small creatures in mud and water. Cardinals, sparrows, grosbeaks, and other finchlike birds have very short, conical beaks.

These beaks are very strong and can break open tough seeds. Spoonbills and pelicans have long, flattened or pouchlike beaks that they use to scoop up

fish and other aquatic creatures. Flamingos and some ducks have bills that act like strainers to filter tiny plants and animals

from the water. (Only certain kinds of ducks are filter feeders.) Nighthawks, whippoorwills, swifts, and swallows have large, gaping mouths that act like

nets to trap insects. These birds catch insects on the wing. Warblers have small, sharp, pointed beaks for picking insects from leaves, logs, and twigs. Toucans have very long, thick beaks for reaching out and plucking fruit from trees.

Many birds, after millions and millions of generations, have evolved very specialized beaks and can eat only one type of food; other birds, like crows, have more versatile beaks and can eat a variety of food.

ENGAGE Share the book BEAKS! by Sneed B. Collard III. This is an excellent book to help students begin to explore bird beak adaptations. Point out that a beak’s main purpose is to obtain food, but the beaks are adapted to what a bird eats and how it gathers food or hunts.

EXPLORE 1. Organize students in groups of four.2. Tell students that each member of the group will pretend to be a bird with a different kind of

beak (clothespin, toothpick, scissors, plastic spoon). Each bird will attempt to eat four different types of food: marble snails, packing foam waterbugs, drinking straw worms, and raisin grubs. The plastic cup will be the stomach. It should be near the food source and standing upright, but it should not be touched at any other time while eating food.

3. Explain how each beak will be used: Clothespin – Hold the clothespin at the very end so it can be opened as wide as

possible. Use only one hand to operate the clothespin. Toothpick – Use the toothpick only as a spear to capture food and not as a scoop.

Use one hand to hold the toothpick and only one finger of the other hand to push food off the toothpick.

Scissors – Use the scissors like tweezers. Do not use them as a spear or a scoop. Use only one hand to operate the scissors.

Spoon – Use only one hand to hold the spoon as a scoop for food.Note: Students should use only one hand at all times to operate beaks, unless otherwise noted. Remind students that they should not become discouraged if they cannot pick up food with the beak. This is an investigation to see which beaks are best suited to pick up certain food sources.

4. Instruct students to spread the marble snails around in the tray. Allow one minute for each group member to try to pick up as many marbles as possible using the various beaks. As food is gathered, students should place it in their plastic “stomach” cups. When time is up, students should empty the plastic cups, count the number of marbles in each cup, and share the data with their group members.

5. Have students make a bar graph comparing the numbers of marbles (snails) each beak was able to gather.

6. Have students scatter the raisins grubs out on the table and repeat steps 4 and 5.7. Have students repeat steps 4 and 5 with the other two food items - packing foam waterbugs

and drinking straw worms.

EXPLAIN1. Have groups of students compare the four bar graphs to answer these questions:

Which was the best beak for collecting grubs? waterbugs? worms? snails?Which was the best beak for collecting a wide variety of foods?Which beaks were unsuitable for certain foods? Why?

2. Have each group share their answers to the questions and discuss any differences that arise. Try to find out what might account for any differences in the data.

EXTEND/APPLY1. Familiarize the students with the following terms:

Food generalists – birds with versatile beaks for eating a variety of foodsFood specialists – birds with specialized beaks that can eat only certain foods

2. Ask: Which of the beaks used in the activity belong to a food specialist?How can specialized beaks help some birds stay alive? (A bird with a specialized beak can often eat a type of food that no other bird can eat.)How might a specialized beak hurt a bird? (If a bird’s habitat changes and its food source is no longer available, the bird might die because it can eat only that food.)Why is it beneficial to a bird to have a more versatile beak? (Some birds, like crows, can eat fruits, nuts, berries, fish, etc. - a variety of food sources.)How do a bird’s beak type and food preference help determine the habitat? (Some birds eat insects or fruit; some birds crunch seeds; and some even eat small animals. Some feed in the day; others feed at night. Birds must live in habitats that provide them with the food, water, and shelter they need.)

3. Display the picture of the ancestral honeycreeper (the first bird on the page – figure 1a). Ask: What type of food do you think this bird eats?

Display pictures of the Hawaiian honeycreepers (the other birds on the page). Ask: What type of food do you think these birds eat?

Ask students if they think these two types of birds might be related, based on their appearance. Read aloud the Honeycreepers information sheet.

ASSESSMENT A pelican eats fish and other aquatic creatures. Describe its beak.

A snipe probes for worms, crustaceans, and other small creatures in the mud and water. Describe its beak.

A cardinal breaks open tough seeds. Describe its beak. Toucans reach out and pluck fruit from trees. Describe its beak. Flamingos filter tiny plants and animals from the water. Describe its beak.

HONEYCREEPERS

Honeycreepers are small birds that originally came from Asia. Millions of years ago, some of these birds flew to the northwestern Hawaiian islands. The adventurous birds were physically isolated in a new land away from the other honeycreeper birds in Asia. The honeycreepers had to find ways to adapt to their new environment and to different food sources. Some of the birds ventured east to other islands, having to adapt to other new habitats. All these birds were physically isolated from one another, and there weren’t many other birds on the island. After many generations, the honeycreepers gradually began to adapt to their new environment, and they began to make changes. Some of those changes were stronger beaks for cracking seeds; long, curved beaks for eating nectar; and sharp, tweezer-like beaks for catching insects.

When some of the Hawaiian honeycreepers returned to their original land, they looked nothing like their original ancestors that they had been separated from so long ago. (Figure 1a is the only ancestral honeycreeper. All the other birds are Hawaiian honeycreepers.)

Birds use their beaks for many reasons: to build nests, attack prey, groom feathers, communicate, and to gather and catch food. Because of these differing needs, a wide variety of bird beaks have developed.
