Science experiment

In this investigation, you are to record the relationship between the height a ball is dropped from, And the height of the balls first bounce.

Equipment: Meter ruler - a tennis ball.

Aim: Make a brief statement of the purpose of your investigation.

To investigate how high a ball bounces from a certain height and to measure the height of the balls first bounce.

Hypothesis: Make a prediction of what you expect to observe during your investigation.

I think that if you drop the ball from a meter high it will bounce back up under a meter.

Method: Give a step-by-step description of how your experiment is to be carried 

  1. Set up the ruler strat.
  2. Drop the ball and record the data from that drop.
  3. Change the height of where the ball is dropped from and see the difference between them.

Key Variables
Dependent: Measure how high the ball drops.
Independent: Changing the height of where the ball drops from. The surface it bounces on. Control: Keep the ball the same.

Drop Times:


Height dropped from/ Height it bounced 
  1. 1 meter high    1. 51cm 
  2. 1 meter high    2. 47cm
  3. 50 cm high      3. 20cm
  4. 50cm high       4. 15cm
  5. 70cm high       5. 22cm
  6. 70cm high        6. 32cm
  7. 2 meters high  7. 75cm
  8. 2 meters high  8. 70cm  
Discussion:
As I increased the height of the drop the bounce increased with it sometimes.
 
Conclusion:
We came to a conclusion that my hypothesis was kind of right.
