A student notices that a basketball seems to act differently depending on whether the game is being played on a court with a wooden floor, on a concrete driveway, or on blacktop in a park. The student hypothesizes that the surface on which a ball is bounced affects the height of the bounce. How can the student design an experiment to test the hypothesis?

A.The student should drop the same ball from three different heights and have someone measure the height of each bounce.

B.The student should drop three different balls from the same height and have someone measure the height of each bounce.

C.The student should drop the same ball from the same height on three different surfaces and have someone measure the height of each bounce.

D. The student should drop three different balls from the same height on three different surfaces and have someone measure the height of each bounce.

Answer: Experimental design means creating a set of procedures to test a hypothesis. A good experimental design requires a strong understanding of the system you are studying. By first considering the variables and how they are related ( Step 1 ), you can make predictions that are specific and testable

Step-by-step explanation:

A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used interchangeably, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research, in a process beginning with an educated guess or thought.
