In a controlled experiment, how many independent variables can be worked with at a time? 

• one
• none
• two or more
• how ever many makes sense.

Mr. S. sets up an experiment to see how the mass of a ball affects the distance it rolls off a ramp. Identify the INDEPENDENT variable.

• distance traveled by the ball

• height of the ramp

• mass of the ball

Mr. S. sets up an experiment to see how the mass of a ball affects the distance it rolls off a ramp. Identify the DEPENDENT variable.

• height of the ramp

• distance traveled by the ball

• mass of the ball

• weight of the ball

A student is planning an experiment to find out how the height from which he drops a ball affects how high the ball bounces. The DEPENDENT variable is the _____.

• Diameter of the ball

• Force acting on the ball

• Height that the ball bounces

• Height from which the ball is dropped

When experimenting with the growth of a plant, a scientist uses three (of the same type of) plants, two different fertilizers, same light, and same amount of water. What type of variable is the fertilizer?

• Dependent

• Independent

• Control

• Compound

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, what is the DEPENDENT variable?

• Type of plant

• Water, apple juice, milk

• Plant growth

• Color of the plant's leaves
