Scientists pay close attention to controls, dependents variables, and independent variable when they design experiments:

A dependent variable:(Depends in another factor) is a variable being tested and measured in a scientific experiment. It is sometimes called the responding variable.

The dependent variable depends on the independent variable. As the experimenter changes the independent variable the change in the dependent variable is observed and recorded. 

A independent variables are variables that the experimenter changes to test their dependent variables.

A change in the independent variable directly causes a change in the dependent variable. The effect on the dependent variable is measured and recorded.
