And Theyre Off! A Lesson on Newtons First law of Motion

Materials: Two Plastic Jars with Lids

o You can substitute these jars with one full can of soup and one empty cano Stay away from glass jars for safety reasons

Flour or Sand to Fill One of the Jars Two Empty 3-Ring Binders at least 25 in width A Yard Stick

Where Materials Can Be Found: These materials can be purchased at Wal-Mart or any other department store.

Procedure:1. As a class, the students and the teacher will brainstorm out loud about what theyknow Newtons laws, specifically the first law (the law of inertia), while I askengaging and meaningful questions about the topic. We will engage inconversation for about 10 minutes.

2. I will then read the book, Newton and Me, byLynne Mayers to the class. Thisbook can be used for grades K-5, but is a great book, written in rhyme, that easilyexplains Newtons Laws to any grade level.

3. We will begin the lesson by filling one jar with flour or sand, packing it in tightly. The other jar will be left empty. The lids should be secured strongly.

4. From there the students will place both of the three-ring binders next to each

other on a carpet or tiled floor. They will then place each jar on its side and release both from the top of the binder ramps at exactly the same time. 5. In the table provided, the students will record how far each jar rolled using a yard

stick. The distance should be measured by the end of the binder to where the jaractually stopped. This data will be recorded in the table.

6. Steps three through four should be repeated for each of the surfaces listed on thetable.

7. In small groups the students will then talk about their recordings and discusstrends they found in their data. They will be asked to answer questions such as,Did one jar always roll farther than the other?, which jar rolled furthest onwhat surface?, did the results depend on whether the jar was filled withflour/sand or if it was empty? If so, in what way? , and did the results depend

on the kind of surface you used? If so, in what way? 8. We will close up the activity in a whole group discussion about the studentsresults and the answers to the questions above.

Safety Precautions: If using glass jars for this activity, make sure the students know that if they drop

the glass or use the glass improperly, it could break and shatter. The teacherneeds to make sure he/she is supervising the students who are handling the glass jars.

Make sure to have each student wear safety goggles just in case the glass breaksor the sand or flour comes out of the jar to ensure it wont get into the students

eyes.Teacher Information:

According to Newtons First Law, each jar will roll in a straight line at aconstant speed unless a force acts on it.

In this experiment, the jars roll in straight lines because there is no force makingthem turn to the left or to the right. However, because of friction, they do slowdown. Students will make an important observation as they conduct the race ondifferent surfaces and will be able to understand the role of friction.

Smoother surfaces create less friction and it is the force of friction whicheventually stops objects from continuing to roll forever in a straight line, this was

found by Gailieo. To explore inertia the students race the jar full of flour against an empty jar. When the race begins, the filled jar moves down the ramp faster than the empty

jar. This happens because its weight is evenly distributed throughout its volume.The empty jars weight consists only of the jar itself, so it doesnt roll quite as fast.Therefore, the empty jar has a greater moment of inertia than the filled jar.

On a tile surface, the filled jar will roll further than the empty jar. However, whenthe students roll their jars on rough surface such as a carpet, the greater weight of the filled jar causes greater friction between the jar and floor. The filled jar willslow down much faster, allowing the lighter, empty jar to roll farther.

Subject Integration: Language arts: The students will write in their science journal a couple of paragraphs reflecting on the activity. They will write about what they learned,why they liked or didnt like the activity, and what they know about NewtonsFirst law.

Math: This activity is a great integration into measuring. Depending on the gradelevel the students can measure the distance the jars travel by either inches or


3/5

centimeters. To further integrate the activity the students will be asked toconvert centimeters into inches.

Extend or Elaborate Material: To elaborate on this activity the students will try rolling off of different size

binders at home. They can also stack their textbooks up and put a piece of cardboard against the books creating a ramp and use a ruler to find the angle of ramp.

Nevada Sate Earth Science Standard: P.2.B.1 Students know the position of and motion of an object can be changed by

pushing or pulling. P.5.B Students understand that forces can change the position and motion of an

object. P.5.B.1 Students know that, when an unbalanced force is applied to an object, the

object either speeds up, slows down, or goes in a different direction.

P.5.B.2 Students know that the strength of a force and mass of an object influencethe amount of change in an objects motion.

Lesson Topic: Oil Pollution

Description of Classroom:3rd grade elementary school class, age ranges from 7 to 8 year olds, 9 males and 11 females, urbansetting, diverse in ethnicities, English is the first and predominant language of each student.

Background:Students are currently in the middle of a unit based on the ocean. This part of the lesson will

inform students about how oil pollution can affect the environment and will also teach them ways to properly dispose of and recycle oil. Content Objective(s):

1. Students will compare the differences between oil polluted water and clean water.2. Students will be able to describe the effects of oil pollution to wildlife.

3. Students will come up with a variety of possible solutions to prevent oil pollution.

Language Objective(s):Students will write a letter to the local newspaper about oil pollution and demonstrate their knowledgeon the subject through their ideas and thoughts on the subject.Nevada Standards:(3)4.6 investigate and describe how changes to an environment can be beneficial or harmful to plantsand animals [L5C3]

Key Vocabulary:Pollution, oil spill, recycle

Teaching Strategies:I will mix cooperative and individual teaching strategies.The students will have a balance between group activities and individual work.

Warm Up Activity:I will start off the beginning of the lesson by reading the book Oil Spill, by Melvin Berger, to theclass. This will introduce the topic of the lesson to the students and give them a little bit of backgroundinformation on oil spillages. We will then have a classroom discussion about the book and I will ask mystudents what they know about oil pollution and its affects on animals and the environment. After that Iwill begin the hands-on activity.

Lesson Sequence:

9. As a class, the students and the teacher will brainstorm out loud about what they know about oilpollution. While I ask engaging and meaningful questions about the topic. We will engage inconversation for about 10 minutes.

10. The students will complete the hands on activity.11. We will begin the lesson by each putting on a raincoat. The raincoat will be used as an example

of human waterproofing, which will introduce students to the topic of birds and how theirfeathers are a waterproofing tool also.12. Students will then be given one cup of water, an eyedropper of oil, and a couple of paper towels

each.13. Students will then submerge a feather into water and then dry it off. This will illustrate a bird's

weather proofing system.14. Finally, the students will place a drop of oil into the water. They will then place the feather back

into the water and try to dry the feather again, however, the students will not be able to dry thefeather, therefore demonstrating how oil spills affect birds.

15. After the hands on activity the students will discuss, in their groups, what resulted after featherswere placed in the oil and how other wildlife can be impacted by oil pollution and they will

discuss the proper technique for disposing of and recycling oil.16. In closing, each student will write a letter about oil pollution and proper recycling and send it toof a local newspaper. In their letters, students may describe the hazards associated with oil spillsproper oil recycling.

Accommodations:The students will be placed in small groups in the beginning of each class, according to the level eachchild is at (i.e. a student having difficultly will surely be placed with a student of mastery), and will beable to ask for peer assistance. I, the teacher, will be available before and after school if help is needed.Homework will also allow for parental guidance.

Supplementary Materials: Feathers Paper Towels Cups of Water Motor Oil Eyedroppers Raincoat

Review/Assessment:Each student will write a letter about oil pollution and proper recycling and send it to the editor of alocal newspaper. In their letters, students may describe the hazards associated with oil spills andimproper oil recycling. I will assess the letters according to the students' knowledge of material and

content, along with proper letter writing format.
