What are the factors that can change in an experiment called?
Environmental factors if you cannot control them.Variable factors if you can control them.See link below for easy explanation:In an experiment the scientist is able to change the independent variable. To insure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens. - See more at: http://www.chacha.com/question/what-part-of-an-experiment-is-the-factor-that-you-change#sthash.iyH25Jac.dpufIn an experiment the scientist is able to change the independent variable.
