The part of the experiment that does not change
The constant in an experiment refers to the part of the experiment that does not change. It is a variable that is kept consistent throughout the experiment so that the only factor being tested is the independent variable. The purpose of keeping a constant is to eliminate any potential confounding variables that could influence the results.
