How about one of those experiments where you harness the energy in a potato? Your project can be "Can we use potatoes to save energy?" What you is you put copper and zinc into a potato, and attach cables to both of them, then connect the cables to a lightbulb (or something like that) and the natural energy in the potato turns the lightbulb on and acts as a battery. A link can be found on my sources, and for additonal info past that just google "potato zinc lightbulb experiment" or something like that.

i know on simple one you need lamp and a amperage meter and an incandescent and a florescent light bulb and simple measure the current that each light bulb draws when you switch them.
