The control variables themselves are not of primary interest to the experimenter. By definition the control in a science experiment is a sample that remains the same throughout the experiment. The control must remain the same or equal at all times in order to receive accurate results. If at any point, your variable could affect the end result of your experiment, it should be considered the control.

Having a control group rules out any environmental variables, such as temperature and humidity, from affecting the conclusion of the experiment. A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable.
