The only way to test a particular variable for sure is to leave all other variables constant, and if a change in ONE variable creates an overall change, then you know that that variable caused it. But if you change 2 variables, and something changes, you don't know which one changed it for sure. So, one variable at a time. A full experiment can test many variables, though. better just to test one variable at a time that way one knows that any changes observed are accounted for by that variable.
1 If you can't measure the results of your experiment, you're not doing science! 2  You must be able to control other factors that might influence your experiment, so that you can do a fair test. 3  A fair test occurs when you change only one factor (variable) and keep all other conditions the same. The experiment should measure changes to the important factors (variables) using a number that represents a quantity such as a count, percentage, length, width, weight, voltage, velocity, energy, time, etc. 2  Or, just as good might be an experiment that measures a factor (variable) that is simply present or not present.
