Any science geniuses here? Can someone explain to me the dependent, independent, and control variables in an experiment? In the experiment I'm supposed to make a food battery out of lemons first, then using the same procedure I'm supposed to use potatoes to see which one works (I have to light up a lightbulb). Is the control variable lighting up the lightbulb? What would dependent and independent variables be? I'm really confused so help would be appreciated. Edit: Guys thank you so much for the help <3
