Detailed explanation-1: -The variable that the scientist changes during their experiment are the independent variable.
Detailed explanation-2: -To insure a fair test, a good experiment has only ONE independent variable. As the scientist changes the independent variable, he or she records the data that they collect. The dependent variable is the item that responds to the change of the independent variable.
