Physics

Recess Racetrack

Lesson Plan

Grade Level:

Grades 1 - 2

State Standards:

Science:
Physics Standard 4 Demonstrate that the way to change the motion of an object is to apply a force (give it a push or a pull). The greater the force, the greater the change in the motion of the object.

Writing:
CC. 8 With guidance and support from adults, recall information from experiences or gather information from provided sources to answer a question.
CC.1 Write opinion pieces in which they introduce the topic or name the book they are writing about, state an opinion, supply a reason for the opinion, and provide some sense of closure.

Essential Question:

What is friction?

Lesson Question:

How do different types of surfaces effect friction?
What surfaces have the most amount of friction? Least amount?

Introduction:

Yay! Our principal has decided to let us build a racetrack next to our playground. You will be able to use the racetrack during recess and after school. You will be able to ride your bike, your skateboard, your scooter, or even roller skate! The principal has asked that you test out different surfaces to determine which surface will be the safest to use when building the racetrack. As you test out the different surfaces, think about which types of surfaces have the most amount of friction? Which types of surfaces have the least amount of friction?

Task:

In order to choose the safest and the most efficient surface, you must first learn about friction. You will watch two videos, look at a Prezi, and learn a song about friction. Next, you will work in groups of three to test out and analyze how a toy car moves on three different surfaces. Finally, you will create a model of the perfect recess racetrack and write a letter to your principal that will persuade him/her to build YOUR racetrack.

Ready...Set...Go!!!

Lesson Experiences:

Day 1

First you and your class will watch the prezi below to learn about what friction is. Listen to your teacher as she reads about what friction is and what would happen if we didn't have friction.

Click on the link below to watch the prezi.

Prezi Friction

Next you will watch 2 videos to learn more about friction.

Click on the links below.

Finally, you will watch and listen to the song below a few times at home as homework tonight. See if you can remember some of the words to the song. We will be singing it in class tomorrow!

Day 2

First you and your two partners will need to get:

Find a spot in the classroom to build your 3 tracks using the wood pieces and the text books to create an incline (hill). Look at the picture below to make sure you set up your pieces of wood correctly.



Before you test any of the surfaces, make a prediction about which surface will be the fastest and which will be the slowest. Write your prediction in your science journal.

Next, line up your 3 cars at the top of the incline. On the count of three, each person will lightly push one of the race cars down the incline.

You will all need to record in your journal which race car comes in first, second, and third.

Repeat the experiment ten times so that you have ten races recorded in your journal.

Put away your materials and then talk with your group about what you notice.

  1. Do you see any patterns?
  2. Which car came in first place most often?
  3. Which car came in last place most often?
  4. What does that tell you about surface friction?
  5. Look back at your predictions. We're you right?

Be ready to share your results and what you learned with the class.

Either at home or during free time in class, try out at least two of the games below to experiment more with surface friction.

Use the checklist below to show which games and quizes you tried.

Game 2

Game 3

Game 4

Game 5

 

Day 3

Using what you have learned about friction, you will now create a model recess racetrack and write a letter to your principal telling him or her why your track is the best. You may work alone or with a partner.

Get markers and a piece of poster board.

Draw your racetrack and label the parts.

Write a letter to your principal that describes your racetrack, tells why your racetrack is safer than other possible racetracks, and explains what friction is and how it affects different surfaces.

Give your model racetrack and letter to your principal...Good Luck!

Now that you are a friction expert, take both of the quizzes below.


Quiz 1

Quiz 2


Conclusion:

At the end of this unit you will have created your own recess racetrack and learned lots about friction.

Assessments:

The quizzes will be an assessment.

The model racetrack will be an assessment.

The letter to the principal will be an assessment.

Knowledge/ Journal

Information is accurate and thorough; demonstrates an advanced understanding of friction.

Information demonstrates a proficient understanding of friction. Directions were followed.

Information demonstrates a basic understanding of friction. Not all directions were followed.

Information demonstrates a below basic understanding of friction. Directions were ignored.

Letter to principal

Student’s position is clearly stated and three or more supporting reasons are given for that point of view.

Student chooses a point of view and writes 2 supporting reasons for that point of view.

Student states a position and gives 1 supporting reason for that point of view.

Only a statement of position is given with no supporting reasons.

Racetrack Model

Use of concepts learned to create track model. Each section of project labeled. Neatly colored, appropriate colors, etc.

Some use of concepts learned to create track model. Neatly colored, appropriate colors, etc. Each section of project labeled.
