hope that helped.

∙ 13y agoEverything in an experiment that can change in some way is a variable. The goal is to have a completely controlled environment where the only changing variables are the dependent and independent variables but often other variables change too.
Experiments must have variables because otherwise there would be nothing to test in the experiment. In an experiment, it is the change in one variable that you are measuring.

∙ 12y agoMany people believe that there is and I strongly do as well. A Controlled variable is something kept the same during the time the experiment is taking place. This could be light, heat or even water. :) Hope I could help

∙ 12y agothe control variable stays the same. that's why it's called the controlled variable. :)
Wiki User
∙ 15y agoYou need a control in an experiment so that you have something to compare your other results too. :) - hope that helps
