Get some plants. Make sure they are all the exact same kind. Put equal numbers of plants in a sunny place and in a dark place. Water them all with the exact same amount of water at the same time every day. After a week or so the plants in the dark should be dying, or at least less healthy looking than the plants in the sun.
