Ball bounce height vs surface material


Squash ball
Metre stick
Clamp and stand
Different materials (e.g. carpet, lino, cork, wood, rubber)

NOTE: ideally materials should all be the same thickness.


Place one material on the floor and use the clamp and stand to support the metre stick next to it.
Next drop the ball from the top of the metre stick onto the surface and record the maximum height to which the ball bounces.
Repeat this experiment at least another two times.
Change the material and carry out another three tests.

Risk Assessment

Ensure the ball does not roll away into an area where it could get underfoot and cause a fall.
When setting up the metre stick make sure it is clamped securely so it won't fall onto people carrying out the experiment.
