variables
Variables that can change are called independent variables. These are the factors or conditions that researchers manipulate or observe to see how they affect other variables in an experiment or study.
Variables that do not change in an experiment are independent variables.
Variables that do not change in an experiment are independent variables.
The variable in an experiment is the element that is being tested or measured. It is the factor that can change or be manipulated to observe its effect on the outcome of the experiment. There are independent variables, which are manipulated by the researcher, and dependent variables, which are what is being measured.
the only variables in an experiment are the independent variables [the thing in an experiment your going to change. and the dependent variables [the thing in an experiment your going to measure.

The thing that you change, from experiment to experiment.
The factors which you change (vary) are called variables.
If you change the variables in a science experiment, you will probably get different results.
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.
