I am experimenting to see how long I can keep cheese from getting moldy in my fridge. I place three groups of fresh mozzarella cheese in the same fridge. I leave one group on a plate in the fridge. I wrap the second group in plastic wrap. I wrap the third group in aluminum foil. I check to see if the cheese molded every two days.
Name a Control, Dependent Variable, and Independent variable in this experiment.
Control: environment (all same fridge/temperature), type of cheese, amount of time
IV: what I wrap the cheese in
DV: time it takes to mold.
