Front

How does changing the height from which a ball is dropped affect its bounce?

The height from which the ball is dropped is the independent variable, and the height it bounces back is the dependent variable.

Front

In an experiment, if the mass of a ball is changed, what is being tested?

Back

The effect of mass on the distance the ball rolls off a ramp.

Front

What is the conclusion in a scientific experiment?

Back

A summary of the results and whether the hypothesis was supported or not.
