Electricity from a Lemon

Electricity from a Lemon | Science Fair Projects | STEM Projects
Have you ever wondered how batteries work? In this experiment, you'll learn about electricity and how to make a battery using just a lemon and a few other materials. You'll even be able to power a light bulb with your lemon battery!


The hypothesis is that a lemon can be used to make a battery that produces enough electricity to light up a small LED light.

Method & Materials

You will use a lemon, a penny or copper wire, a galvanized nail or zinc strip, and some alligator wires to create your lemon battery. After setting up the battery, you will connect the wires to a small light bulb to see if it lights up. You can even test the voltage with a voltmeter.
You will need a lemon, paper towels, a penny or copper wire, a galvanized nail or zinc strip, alligator wires, and small LED light bulbs.


In this experiment, a battery was made using a lemon and was able to power a small light bulb. It also shows how alternative sources of energy can be used to power small devices.

Why do this project?

The lemon battery shows how electricity can be generated by chemical reactions. It's fascinating to see how normal everyday items are able to generate electricity to light up the LED light!

Also Consider

Try using different fruits or vegetables as the electrolyte solution to see which produces the most electricity. Test different metals as the electrodes to determine which combinations create the most powerful battery.
