Hello,

First you need to isolate a variable that you want to test. For example, which brand of hair gel keeps hair stiff the longest? Then you need to design an experiment that allows to run some tests on your variable (measuring the amount of time a particular brand can keep hair stiff for example). We have a comprehensive, step-by-step science fair help guide online so be sure to follow the steps in the scientific method:
