What of science is using a potato to light up a light bulb?
Using a potato to light a lightbulb is called an electrochemical reaction. There is a reaction that happens between the potato and the metal you insert into it that generates electricity, or flow of electrons, which can power a light bulb. Check out the sites listed in the “sources” section below for more information on electrochemical batteries. This can either be a project in Chemistry or Physics depending on what you focus on. If you focus on the chemical makeup of the potato, and/or the reaction that takes place, then it would be mainly Chemistry. Physics would be more concerned with the strength of the current, and the structure of the circuit that you create. Good luck! Feel free to email or msg me if you have any more questions. I’d be glad to help you get started with the project.
