Bouncing Balls

Aim:
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
• 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:




Height of Drop	Height of Bounce on carpet
80cm
90cm
100cm
