Science Experiment:

Aim: To investigate the relationship between the height of a ball dropped from a height.

Hypothesis: I think the higher you drop the ball the half its height it's going to bounce.

Equipment needed: Metre ruler, Tennis ball ( or any other ball),

Method: 
1. Get a tennis ball
2. Put any measuring tool ( Ruler ) against a something straight to support it.
3. Drop the ball from a height of your choice 3 or 4 times to see the difference ( drop it from different heights)
4. Watch the first bounce a see what height it stopped at.
5. Write the recorded data and place it on a graph.

Key Variables:

Dependant:  The height of the first bounce

Independent: Where you drop the ball from ( The place where you drop it from)

Control: The same equipment.

Results :
Height
1. 60cm - first bounce 30cm
2. 60cm - first bounce 31.5cm
3. 70cm - first bounce 36cm
4. 1 metre - frist bounce 46.5 cm
5. 1 metre - first bounce 49 cm
6. 150cm - first bounce 67cm
7. 150cm - first bounce 66cm
8. 257.7 - first bounce 96cm
9.257.7 - first bounce 107cm

Discussion: 
I found out that there were different results to each trail. If you dropped the ball twice from the same height it would have different results.

Conclusion:
My hypothesis was that if a dropped a ball from a certain height it's first bounce would be half it's height. I was right because my hypothesis is similar to what happened.
