How does a lemon battery work? The science behind how food can power a light bulb is really fascinating. You can also use limes, oranges, potatoes, pumpkins/squash, or other acidic foods. The goal of making a lemon battery is to turn chemical energy into electrical energy, creating enough electricity to power a small LED light. Now using your multimeter test your energy levels. Insert a copper plate on one side and a zinc plate on the other side. It is very important that you place these far enough apart that the electrodes don’t touch. Start with one lemon and make a small cut through the peel on either end. This releases the juices inside and we want our lemons as juicy as possible. Just like you would if you were about to eat or juice them. See all the amazing things your young scientist can do with MEL Science. We LOVE MEL Science, it is one of our favourite educational subscription boxes. MEL Science does Lemon Batteries as one of their monthly experiments. Looking for a quick out of the box solution? Copper wire can also be used, and a search of your local hardware store is likely to produce other copper and zinc items you could test in your experiment. Lemons! You need at least 4 to create enough energy, but why not grab extras and experiment?Īlligator clips with wires (2 per cell, so minimum 8 if you are creating a 4 cell battery)Ĭopper and Zinc plates are invaluable in our science experiments, but if you don’t have them, you can use copper pennies (the older the better) and zinc plated (aka galvanized) nails. Note: These food based battery experiments produce low voltage and are safe for older, responsible children to do under adult supervision. So when we went grocery shopping and there was a huge pile of fresh, juicy looking lemons on display the kids asked to buy some for lemonade, but I knew we had another science experiment in our future. Plus, when a child starts a science experiment with serious doubts, yet still achieves success, it powers up their curiosity! Why? Because it makes things real that they can’t otherwise see. Then, once they stopped straining their eyeballs, we built a potato battery and it worked! These kinds of science experiments for kids really stick with them. You should have seen the looks on their faces! Serious side eye was thrown my way. Normally our circuits are powered by batteries, but one day I convinced the kids we could power a light bulb with nothing but a potato. That energy isn’t just some crazy weird thing that I babble on about, it is this very real power that is showing itself right in front of them. When we can power a light bulb with that energy it suddenly makes it very real for my kids. We often talk around here about the energy in nature and in everything around us.
