Bouncing Balls

Aim: I want to find out if there is a relationship between how high the ball is dropped form and how high it bounces up.

Hypothesis: I predict that the higher the ball is dropped from the higher it bounces up.

Method: The equipment that I will need is.
Bouncy Ball
Ruler
Stand with boss head and clamp if you are by your self.

Height of the drop	Height on carpet	Height on concrete
80cm	33cm	50cm
90cm	39cm	61cm
100cm	41cm	51cm

Finding:

At 80cm the ball bounced up 33cm on carpet and 50cm on concrete.
At 90cm the ball bounced up 39 cm on carpet and 61cm on concrete.
And at 100cm the ball bounced 41cm on carpet and 51cm on concrete

Conclusion:
The ball bounced higher when it was on concrete then carpet and on concrete it went the highest on 61cm but on carpet it was 41cm. So I think that the balls bounce higher on concrete.
