Bouncing Ball

Aim: I want to investigate how high a ball will bounce when it's been dropped from different heights.

Hypothesis: I predict that when the ball is dropped, it will bounce lower than it is dropped.

Method:

The equipment I need:

• Golf Ball
• Ruler
• Stand with boss head and clamp 

1. Attach the clamp to the stand

2.  Attach the ruler onto the stand (make sure the zero mark is on the ground) 

3. Hold the ball and drop it from the 100cm mark

4. Film the process to make sure you know where it bounces too

5. Repeat the experiment twice and record the measurements

6. Repeat the experiment using different heights  

Variables:

Independent Variables: The height from where the ball drops.

Dependent Variables: The height of where the ball bounces.

Controlled Variables: The surface the ball bounces, The type of ball, The Ruler.

Heights of Ball Dropped:

100cm = 84cm  

70cm = 60.5cm 

50cm = 44cm 

20cm = 16.5cm
0cm = 0cm

Discussion: Everytime we dropped it, it bounced a little less.

Conclusion:
