Powering Up with Potatoes

Powering Up with Potatoes | Science Fair Projects | STEM Projects
Have you ever wondered how to make a battery from potatoes? In this experiment, you'll learn how to make a battery from potatoes and measure the voltage and current it produces.


The hypothesis is that potatoes can be used to create a battery.

Method & Materials

You will select two different metal strips and one potato, attach wires from the meter's probes to the metal strips, and measure the voltage and current.
You will need metal strips, potatoes, a multimeter, wire clips, and steel wool.


The experiment showed that potatoes can be used to create a battery. The combination of copper and zinc produced the most voltage and current.

Why do this project?

This science project is interesting and unique because it shows how everyday items can be used to create a battery.

Also Consider

Experiment variations to consider include testing different metals to see which produces the most voltage and current, and wiring up two potatoes in series.
