Level 1: Cells• Smallest working unit of living things.• May serve a specific function/job within

an organism, or may live alone (unicellular).

• Ex: bone cells, cartilage cells, red blood cells.

Level 2: Tissues(No, not THAT kind of tissue!)

• Made up of cells that are similar in structure/function that work together to

perform a specific function or job.• Ex: Humans have FOUR basic tissues:

connective (fat, cartilage, bone, blood); epithelial (skin), nervous and muscular

Level 3: Organs

• Made of tissues that work together to perform a specific activity.

• Ex: lungs, heart, stomach, brain.

What other organs can you think of?

Level 4: Organ Systems

Groups of one or more organs working together to perform

specific functions for the organism.

Our human body has 11 organ systems. Can you name them?

Level 5: Organism

• Entire living things that carry out all basic life functions.

Meaning… they are made of cells, share similar chemicals, can take in and use

energy, grow and develop, reproduce, and sense and respond to changes in their

surroundings. They’re ALIVE!

Organisms are usually made up of many cells but some organisms can be made up of only

one cell such as bacteria.

“Squirrel of Organization” In each circle, draw a colorful

representative picture to match that specific level. For

example, in the circle labeled “cell”, draw a picture of a

specific type of cell you might find in a squirrel.

The cell theory tells us that…

1. All living things are made up of cells2. Cells are the smallest working units of all

living things3. All cells come from pre-existing cells

through cell division

What is a Cell?Cell: the smallest unit that is

capable of performing life functions.

8/29/11 The Microscope pg 25Sponge: P.58: 1. Explain the difference between the organisms in figure 18.One organism is a water flea magnified 40 times the other is a spirogyra magnified 300 times.2. The spirogyra in figure 18 is a plant-like protist, why is it green?It is green because it has chlorophyll in chloroplast to capture sunlight to make food.

History of the Microscope1000 A.D - First use of lenses to view images of Greek & Roman writings1590 – Dutch lens makers Hans & Zacharias Janssen make the first microscope by placing two lenses in a tube1665 - Robert Hooke is first to describe and coin the phrase "cell" when observing a slice of cork using a microscope power of 30X 1675 – Anton van Leeuwenhoek “father of microscopy” uses a simple microscope with one lens and is the first to describe bacteria

Label both the diagram and the function:

• Body Tube - Hollow tube that may hold lenses or mirrors.

• Nosepiece - Holds the objective lenses; rotates to use different lenses.

• Middle Objective - Objective with power of 10x

• Low Objective - Objective with power of 4x (Smallest objective)

• High Objective - Objective with power of 40x (Longest objective)

• Stage Clips - Holds the slide in place • Iris Diaphragm - Controls how much light

shines through• Lamp - Provides the light that shines through

the slide• Eyepiece - The part you look through - also

has a 10x lens in it• Arm - Supports the body tube and makes a

good handle for carrying the microscope• Stage - The place where you set the slide• Coarse Adjustment Knob - Used for finding

stuff under low power, moves the stage up and down, too

• Fine Adjustment Knob - Used for high-power focusing

• Base - Supports the weight of the microscope

How should you ALWAYS carry a microscope? Tucked in like a football; with one hand under the

base and one around the arm. Eyepiece Magnification Objective MagnificationTotal Magnification = (10x) X (# on Objective lens)

Find the Total Magnification for the following objective lenses:

1. objective = 4x4X10=40 times!

2. objective = 10x10X10=100 times!3. objective = 40x40X10=400 times!

Here’s what a letter “e” from a newspaper might look like on a prepared slide. Use this image to help you answer

the following questions.

Write a Hypothesis on your paper about what you think will happen once you look at the letter “e” through the microscope: We know that microscopes will make images appear larger. What else do you think will happen to the image of the letter “e” when looked at through the microscope?

Microscope “E” Lab

Data and Conclusions:

1. Using the COARSE adjustment knob with the microscope on LOW power, raise the stage until the “e” can be seen clearly. Draw what you see below in the LOW POWER circle. Change the nosepiece to MED/HIGH Power - you’ll notice the “e” is out of focus. DO NOT TOUCH the Coarse Adjustment knob, instead use the FINE adjustment knob to sharpen your picture. Draw what you see in the MED/HIGH power circle.

2. Compare what you see through the eyepiece and the “e” that you see on the stage. Don’t say it looks bigger…look closely! What happened? Why do you think this happened?

3. Looking through the EYEPIECE, move the slide to the upper right area of the stage. What direction does the image move through the eyepiece?

4. How does the ink appear under the microscope compared to normal view?

5. Why do you think a specimen placed under the microscope has to be thin?

6. Was your hypothesis from above supported? Why or why not?

7. How does the letter “e” as seen through the microscope differ from the way an “e” normally appears?

9/9/10 Ecosphere Mystery! Page 29Objective: Explain what happens during the process of photosynthesis and respiration

Bell work: There is no need to add the nutrients necessary for life. How do the shrimp and algae survive?

Graphic Organizer

Use the following words to fill in the organizer:

Glucose(2) carbon dioxide(2)oxygen(2)

Water(2) photosynthesis sugarSunlight mitochondria chloroplastEnergy ATP cellular respiration

Photosynthesis occurs inside the chloroplast of the PLANT cell. It uses the carbon dioxide and water given off by animals along with sunlight to create sugar (also known as glucose) for food as well as oxygen as waste.

Cellular Respiration occurs inside the mitochondria of the ANIMAL and PLANT cells. It uses the Oxygen and Glucose made by PLANTS to create Energy (ATP) for daily cell processes and also creates Carbon Dioxide and Water as waste.

It’s a Cycle!...

The Cycle of Life

What is the equation for photosynthesis?H2O + CO2 + sunlight => C6H12O6 + O2

What is the equation for cellular respiration?C6H12O6 + O2 => H2O + CO2 + ENERGY (ATP)

They’re backwards of one another!!!

Is there life on other planets?You are a crew-member on a space ship that is on an

exploration mission searching for life on other planets. The commander of the ship has sent you and three of your crewmates to the surface of a newly discovered planet. Your mission is to solve a mystery. You must find out what gas the other life forms exhale. Your only clue is a CD video clip of one of the other life forms exhaling through a straw into a clear container labeled “bromothymol blue.” At the beginning of the video clip the solution inside the “bromothymol blue” container is yellow; however, after the other life form exhales into the container for a period of time the “bromothymol blue” solution turns from yellow to blue.

The atmosphere of this new planet is 21% oxygen and does not contain any known toxins so your commander sends you to the surface without a space suit. You and your team are equipped with a solution of bromothymol blue, safety glasses (four pairs), a clear container, a straw and a plastic bag containing water and a sprig of an aquatic plant. Each member of your team has been assigned one of the following roles: documentation officer, timekeeper, peacekeeper, or materials manager. You have 25 minutes from the time of your arrival on the new planet to solve the mystery and ready yourself to return to your ship.

How do we do this?Here are some questions to ask yourself as you

work…1. What color does the bromothymol blue

solution turn in the presence of carbonate water?

2. What color does the bromothymol blue solution turn after you exhale into it for approximately two minutes?

3. What do you think would happen if you put the aquatic plant into the bromothymol blue solution?

4. What gas (or gases) can bromothymol blue serve as an indicator for?

Need more help?

5. What gas do you exhale?6. What gas do plants give off?7. How long (in seconds) did you have to

exhale into the bromothymol blue solution to elicit a color change?

Is there life on other planets?

What type of gas does the alien life form breathe?

How do you know? Explain, using evidence from your

experiment.

9/10/10 You’re an Organelle! Page 31Objective: Demonstrate knowledge of cell functions by

individual organelles. In our play so far, what organelle is missing

and what is its job?I’M THE NUCLEUS and I direct the cell’s

activities!! Scenario: First we’ll make FOOD inside the

plant cell, and then when an animal eats the plant, we’ll use that food to make ENERGY or ATP during cellular respiration! Then we’ll use that energy to make protein!
