An independent variable is the same thing as a test variable, so it is what you are testing. If you want to find out which chocolate is more fattening, you are TESTing to see if Hershey's or M&M's. You are TESTing the chocolate (to see which is more fattening)
It is the variables you will not change to keep the experiment a fair test, they should be kept constant to show how your independent variable affects your dependant variable.

A well designed science fair project should have one independent variable, one dependent variable, and lots of factors that are held constant as you repeat the experiment several times to verify your results.
go on google and type in science fair projects its that simple

the independet variable would be the type of fruits used and the dependent variable would be the electricity they generate.

A fair test is when you test something equally changing the variables but keeping everything else the same
