Mrs. Ahlers set up an experiment to see how the mass of a ball affects the distance it rolls off a ramp. What is the dependent variable?

• Distance traveled by the ball

• Height of the ramp

• Mass of the ball

• Where the experiment took place.

Why is it important to have only one independent variable and to control the other variables when performing science experiments?

• So you can tell which factor is causing the change in the experiment.

• It does not matter, you can have as many independent variables as you want.

What is the Independent variable in this Hypothesis: If plants are watered, then the height of the plant will increase.

• The increased height of the plant

• The plants being watered

• neither of these
