ONE TWO THREE ISAAC NEWTON AND ME

Exploration One

PURPOSE:

What affects a body's motion?

RESOURCES/MATERIALS: - Part One

1. Three raw eggs
2. Three empty toilet paper rolls
3. Three 1000 ml beakers
4. One sheet of cardboard - 2' square
5. Broom
6. Paper towels
7. Hovercraft, air source and extension cord (or skateboards)

ACTIVITIES AND PROCEDURES: Part One

• Arrange the cardboard, toilet paper rolls, and beakers as demonstrated by the teacher.
• Predict what will happen to the toilet paper rolls when you hit the cardboard sheet with the broom handle.
  Write the prediction.

  Using the broom handle, hit the edge of the cardboard as per the teacher's verbal instructions.

  Record your observations.

  Repeat steps 1-4, but this time balance raw eggs on the toilet paper rolls.

  Stand or sit on the hovercraft.

  Predict your motion when the hovercraft starts to hover.

  Write the prediction.

  Turn on the hovercraft and describe what happens to you and the craft.

  Have your lab partner give you a push or pull and then let go.

  Describe your motion. If you do not have hovercraft, do this on a skateboard and ignore numbers 6,7 & 8

  You have just experimented with Isaac Newton's First Law of Motion. Tell me what you have learned.
