Mark observes that when his father throws a basketball, it bounces higher than when Mark throws the same ball. He wonders, "Is this because my dad is much taller than me?"What can Mark do to best answer his question?

Mark should throw the same ball from different heights and compare how high it bounces. This tests whether the height it is thrown from affects the bounce, which is the idea behind his question; shopping for another ball would change an unrelated factor.
