If you haven't tried making play dough circuits, you're in for a treat!
We love this activity!
Well the boys love it because it's so much fun.
I love it because there's so much learning involved! But more on that in a moment.
Materials Needed For Homemade Play Dough Circuits
The equipment for this activity is fairly simple although you'll have to gather a few items which you may not have at home. This is what you'll need:
- Two types of homemade play dough. One is made with salt which will conduct electricity. The other is made with sugar which doesn't conduct electricity.
- LED - light emitting diodes
- A power source such as a battery pack. (We didn't have a battery pack but did have a transformer which did the same trick).
Recipes for Conductive and Non-Conductive Play Doughs
The conductive play dough is a cooked dough which is really easy to make.
The non-conductive play dough is uncooked.
