Question

bernie is playing with a tennis ball and a soccer ball. he notices that when he drops the balls, the tennis ball bounces differently than the soccer ball. he wonders what factors affect how a ball bounces when it is dropped. so, he decides to design an experiment. he has the following supplies available: one tennis ball one soccer ball a two - meter - tall ladder a meterstick using only these supplies, which two questions can bernie investigate with an experiment? does a basketball or a tennis ball bounce higher when dropped from one meter high? when a tennis ball and a soccer ball are dropped from one meter off the ground, which ball bounces higher? what type of soccer ball bounces higher when dropped from two meters off the ground? does a soccer ball bounce higher if it is dropped from one meter high or from two meters high?

Explanation:

Bernie has a tennis ball, a soccer ball, a two - meter - tall ladder and a meterstick. He can use the ladder to set different drop heights and the meterstick to measure bounce heights. He can compare the bounce of the tennis and soccer ball from the same height (addressing the second option). He can also change the drop height of the soccer ball to see how it affects the bounce height (addressing the fourth option). He doesn't have a basketball for the first option, and he only has one soccer ball so can't test different types for the third option.

Answer:

When a tennis ball and a soccer ball are dropped from one meter off the ground, which ball bounces higher?
Does a soccer ball bounce higher if it is dropped from one meter high or from two meters high?
