Answer

B. The tennis ball will make a deeper crater.

Answer

C. Both craters will be the same depth.

Answer

D. The objects will not make a crater.

Question 13

When designing a simple experimental investigation that tests the effect of force on an object, why is it important to test one variable at a time?

Accepted Answer

B. It allows the experimenter to correctly and more easily interpret the results of the experiment.

Answer

A. It would be impossible to test two variables during an experiment involving force.

Answer

C. It allows the experimenter to formulate a hypothesis both before and after the experiment.

Answer

D. It is not important to test only one variable at a time.
