You need to control the variables because if you have two or more variables in an experiment you will never know which variable caused a change or not caused a change.

What are constant variables and y r they important in an experiment?

. Constant variables are variables which cannot be changed with the experiment. To remember their name is easy just think about Constance. They are important to an experiment because without all three variables there would be no complete experiment. Also the constant variables are important to an experiment because they help complete the result. Without a constant variable you. Would not be testing correctly
