A list of the steps anyone could follow to conduct an experiment. 

• obervations
• question/problem
• materials
• procedures

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

• distance traveled by the ball

• height of the ramp

• mass of the ball

• weight of the ball

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

This part of the experiment serves as a basis of comparison. The independent variable being tested is not included in this group.

• experimental group

• control group

• data

• variables

Why do we want to test only one independent variable at a time?

• Because it is hard to setup a data table with more than one variable
• To better identify what is causing the changes
• It is what has always been done
• It's easier to perform the experiment
