Variables in Your Science Fair Project

A **variable** is any factor, trait, or condition that can exist in differing amounts or types. An **experiment** usually has three kinds of **variables**: independent, **dependent**, and controlled. The independent **variable** **is** **the** one that is changed by the scientist.
