If different students are performing an experiment to see how high balls bounce, what can they do to make sure their results are the same?

• make sure the balls are the same color

• make sure the balls are the same size and material

Joseph wants to investigate how the angle of a ramp affects his skateboard's speed.

• use three different skateboards

• change the angle of the ramp each time

• use different wheels on the skateboard each trial
