Topic: Conservation of energy Scenario:

During lunch break at school Bethany noticed that her rubber ball did not bounce
as high, as it normally would, when it landed on a paper towel. Bethany now
claims if more paper towels are added the rebound height of the ball should
decrease by a fixed ratio.
Plan and design an experiment which can be carried out to investigate Bethany's claim.
