## Process

You will begin by viewing two presentations on Newton's Laws.

1.  Click here to access the worksheet needed to answer some questions as you view the following presentations. Or, you can get a copy of the worksheet from your teacher. (15 points)

2. Click on Humpty Dumpty to watch the presentation about Newton's first law.

3. Click on the train to watch the presentation about Newton's second law.

4. Click on the perpetual motion machine to read about all three of Newton's laws. This might take some time, but you need to read through each page and think about the questions. (Read instruction #5 before you start #4.)

5. When you come to the end of the lesson, get a copy of the quiz from your teacher and complete it. (5 points)

 First Law Second Law All Three Laws

Now it is time to conduct some experiments online.

Experiment #1 (15 points)

1. Click on the paper to review the worksheet you will need for the online lab. Get a copy of the worksheet from your teacher to record your results.

2. Click on the man pushing the boulder to find your experiments. Once you are at the site you will have to click on "Galileo's Experiment" and "Another of Galileo's Experiments" to conduct your research.

 Worksheet Galileo's Experiments

Experiment #2 (15 points)

1. Click on the paper to review the worksheet you will need for the online lab. Get a copy of the worksheet from your teacher to record your results.

2. Click on the Moving Car to find your next experiment. Once you reach the site, click on the "Colliding Cars" link. Read the page before you press begin to start the experiment.

 Worksheet Bumper Cars

Now it is time to build your balloon racer. Click on the race car to find the rules and some helpful hints.

 Rules and Hints

After you finish the race come back and complete these reflection questions from Balloon Racer .

Be sure to answer the questions below. (15 points total)

1.        Newton's first law states that an object in motion will stay in motion unless an outside force acts on it.  What did you do to prevent any outside forces (such as friction) from acting on your car? (3 points)

2.        Newton's second law states that if the same amount of force is used, lighter objects will accelerate faster than heavier objects.  Specifically, how did you manipulate your car's mass? (3 points)

3.        Newton's third law states that for every action, there is an equal and opposite reaction.  Draw a picture of your car.  Label the action force and the reaction force on your car. (3 points)

4.        Write a paragraph to explain at least 3 ways you could improve your car design from your original design. (3 points)

5.        What are three pieces of advice that you would give to someone trying to make one of these cars next year? (3 points)

Using technology, create a step by step "how to" manual that describes how to build your race car.

• The cover must include a title, the names of each group member, and a picture of your finished racer.
• The second page must include all materials needed to build the car.
• The manual should be written in easy to follow, step by step instructions. Diagrams should be used to show the different stages of the car as it is being built.
• The manual must be neat and organized, free from spelling errors, and easy to read.
• Each page should be numbered.
