I want to find out if there is a relationship between how high a ball is dropped from and how high it bounces up.
Hypothesis:
I predict that the higher the ball is dropped from, the higher it bounces.
Method:
The equipment that I will need is:
- Bouncy ball
- Ruler
- Stand with boss head and clamp
Height of drop
|
Height of bounce on carpet
|
Height of bounce on concrete
|
80cm
| 10cm | 39cm |
90cm
| 21cm | 36cm |
100cm
| 31cm | 43cm |
Findings:
The ball bounces higher in concrete than in the carpet.

- Attach the clamp to the stand.
- Clamp the ruler onto the stand so that the zero mark is on the ground.
- Hold the bottom of the ball on 50cm and drop.
- Record the height of the bounce measuring the bottom of the ball.
- Repeat the experiment twice more and record the average measurement.
- Repeat the whole experiment using heights of 60cm, 70cm, 80cm, 90cm, 100cm
Variables:
Independent (changing) Variable = The height of the drop
Dependent (measured) Variable = The height of the bounce
Results:
Conclusion: It bounces higher from 90cm to bounce to 36cm in the concrete.
It bounces lower from 90cm to bounce to 21cm in the carpet.
