Multiple projects with one kit
One kit lets you build and explore two different types of batteries: a saltwater battery or a simple battery using potatoes (or other produce of your choice). There is no better way to learn how batteries work than by building one yourself. Science Buddies project instructions guide you through the building so you can start learning all about batteries, voltage, current, resistance, and more!
Designed for science projects
- reusable electronic components that allow you to conduct multiple tests and/or build two different kinds of batteries
- oversized electrodes that maximize the amount of current generated by your battery, so you can easily compare results from each of your tests
- a quality multimeter so you can get accurate measurements of the power output produced by your battery
- new and improved instructions feature lots of images to guide you step-by-step through the building of the battery and how to capture readings using the multimeter included in the kit
We make it easy for you to get started, but what you decide to explore is up to you. Which produce makes the most power? How much power is created when the batteries are connected in series or in parallel? The possibilities are endless!
This kit is compatible with a number of different projects from Science Buddies. Please see our list of projects and instructions .
Each kit contains:
3 Copper electrodes 3 Zinc electrodes 6 Alligator clip leads 1 Digital multimeter with test leads 1 Piezoelectric buzzer 3 Super bright, high-efficiency red LED

- Very pleased
My son (8 years old) completed the science project easily and understood everything along the way. He had fun and learned a lot. He also took first place in the electrical division at the school science fair! I was very pleased with the kit and will definitely buy from Science Buddies again!
- Producing Power!
My son had a wonderful experience learning how to make battery potatoes. He's 7, but he was up to the challenge since we kept the experiment simple. We tested three sizes of potatoes, and then continued to measure them over time. He won first place in his science fair today, and had a great time explaining it to everyone who would listen. He had some big audiences!
The kit was great, and the instructions on the website were very helpful. However, I was an amateur with using the millimeter, so determining the correct setting to measure the potato was the most difficult part of this experiment. Although we found the instructions provided by Science Buddies on how to use the millimeter, they are a bit general in how to use it, so it was difficult to know if we were using it appropriately. I would greatly appreciate clearer instructions with the millimeter that are directly applicable to the potato experiment.
Other than that, we had a great time. Thanks Science Buddies!
