VARIABLES
What is a variable?
A variable is any factor, trait, or condition that can exist in differing amounts or types.
Types of variables ...
Control(s) - A control is something that remains constant (does NOT change) in the experiment.
Independent variable(s) - This variable is factor, trait, or condition that is changed by the scientist and is used to create a fair test. A good experiment has only one "change" that allows the tester to observe what happens as result of this change.
Dependent variable(s) - A dependent variable is a factor, trait, or condition that happens as a result of independent variable --- thus, what are you testing for as a result of your independent variable.
ALL variables MUST BE MEASURABLE -- such as length, distance, speed, rate, etc.
