investigation

Equipment

meter ruler

tennis ball

report stand

boss head and clamp

Aim ; is to see how high  the ball bounces from the first bounces  and from how high we drop it from.

Hypothesis; i think the higher we drop the ball the higher the bounce will be.

method;

1) get a ball
2) get a meter ruler to measure how high you are going to drop it.
3) then drop the ball from measured height.
4 then measure the height it bounced on the first bounce.
5 record your results.
6 then try it again from different heights.

DEPENDENT;
the height of bounce of the ball.

INDEPENDENT
changing height of the ball from where its dropped from
CONTROL
the ball  does not change.

Independent

the person who is doing the experiment gives to the next person

Discussion
When the ball bounce forces bring down

Conclusion
The result supports the hypothesis

Evaluation
Next time maybe we need to use a basketball and do the bouncing the ball over and over

Dependent  

The measure when you drop the ball
