Materials:
|
- Several pieces of paper
- 8 x 11 inches
- A book approximately the size of the paper
|
| Directions: |
- Crumble up one of the pieces of paper into a ball. Hold the ball of paper and a sheet of
paper out and drop these simultaneously asking students to observe which will hit the
ground first. Next, challenge the students to devise away in which they can have each
piece of paper hit the ground at the same time without altering either piece of paper.
Place the flat sheet of paper on top of a book and drop.
|
| Safety Concerns: |
- None
|
| Questions: |
- Why do the objects fall at different rates?
- Why does the flat paper float to the ground?
- How could you make it move faster?
- What role does the book play?
|
| Concepts: |
- The book acts as a barrier to the air. It diminishes the air resistance against the
paper directly. It is the air resistance that is causing the flat piece of paper to float
to the ground.
