A control in science is in an experiment that makes sure the science experiment only tests one variable. A constant is in an experiment and that is a variable that never changes.
Controlling for a variable is the act of deliberately varying the experimental conditions in order to take a single variable into account in the prediction of the outcome variable. Controlling tends to reduce the experimental error. A control is something that does not change in the experiment.
Thats what makes the variables what they are by definition they are what is changing
