A variable.
Control Variable
The variable in an experiment that remains the same is known as the control.
Environmental factors if you cannot control them.Variable factors if you can control them.See link below for easy explanation:In an experiment the scientist is able to change the independent variable. To insure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens. - See more at: http://www.chacha.com/question/what-part-of-an-experiment-is-the-factor-that-you-change#sthash.iyH25Jac.dpufIn an experiment the scientist is able to change the independent variable.

a variable
The dependent variable is the variable that can change in an experiment.
Constant variable
the dependant variable
The variable that stays the same throughout the entire experiment is called the control.
A variable.
A variable.
The independent variable is also called an experimental variable. It is the variable being manipulated in the experiment in order to show the effect on the dependent variable. The dependent variable is also called the response variable. It is the variable being observed in the experiment. A change in the independent variable is what causes the change (if any) in the dependent variable, which is the purpose of the experiment.
In an experiment, factors that you change are called independent variables.
A factor in a scientific experiment that is subject to change is called a variable.
The independent variable.
The part of an experiment that you test or manipulate change is called your independent variable.
