NATIONAL GEOGRAPHIC Battery Making Kit - Potato Clock and Penny Powered Flashlight!


The National Geographic Electricity and Battery-Making Kit lets kids build two functioning science projects: a potato clock with voltmeter, and a coin-powered flashlight!

With this kit, kids will be able to:


  • Construct and install the circuit components of a potato clock
  • Build a "penny battery" from the ground up with the included copper discs
  • Test the voltage of the potatoes powering the clock
  • Use the included flashlight with the battery they've built
  • Learn all about electricity and circuits


This is a great science project for the classroom or a fun, at-home activity! Kids get all the components they need to build a working potato clock, all they need is two potatoes! The clock also doubles as a voltmeter, so kids can see the voltage produced.

After that, kids will get to build a battery from the ground up. Copper, magnesium, and cardboard "coins" are included in the kit along with a battery compartment and easy-to-follow instructions. Kids can then use the battery they've made to power their own flashlight!

The detailed learning guide provides insight into the science at work in the electrical circuits kids create. This is a fantastic STEM gift for girls and boys and a great way to inspire a love of building and science!
