About the Pictures Image Gallery
The term control variable has different meanings, depending on the area in which it is used. In scientific experimentation, a control variable is one that must not be changed throughout an experiment because it affects the independent variables and thus affects the outcome of the experiment. For example, in the experimental verification of Boyles law, the temperature must be kept constant. It basically is the thing you keep the same.
