Whenever I hear “September” I think of one thing, and that’s the start of school. As summer comes to an end and the new school year begins, this is a good time to talk about some practical and fun uses for batteries. I have a few everyday uses and a couple other exciting projects that are a great way to get a basic understanding of batteries while having a little fun at home or school. I am sure everyone knows about the classic potato battery, but I have rummaged around the internet to find other projects that will make learning and teaching even more enjoyable.

Here are some of the more basic, everyday uses for batteries in the classroom:keyboard
  • - Clocks
  • - Phones/radios
  • - Flashlights
  • - Laptops
  • - Calculators
  • - Cameras
Here are a few uses that you might not think about until you desperately need them. Make sure you order the batteries you might forget are needed and keep a small stock of them for emergencies!battery collage
  • - Projector remotes
  • - TV/VCR remotes
  • - Wireless microphones
  • - Wireless computer mouse
  • - Wireless keyboard
Here are some other great ways to use batteries in the classroom or at home! These projects are relatively easy to do, do not take a ton of materials, and are a great way to work in pairs or small groups.
