In some experiments you may find that one piece of fruit, such as a lemon, can produce lots of electricity, enough to light up a LED or the clock module. In other cases you may have to use 3 or 4 or even more pieces of fruit to get good results. This is very much the same as with batteries.

Science Fair Project ideas Experiment with various fruits to see which one produces the most electricity with the least amount of pieces - lemon, orange, lime, grapefruit. Use a multimeter to meaure the energy output. Experiment with electrodes in salt solutions and note the difference. What produces a stronger electrical current, an acid or a base?
