Flat Flashlight
Source Institutions
In this activity, learners build a tiny but powerful flashlight out of simple materials. Use this activity to introduce learners to electrical circuits and conductivity.
Shocking Fruit
Source Institutions
In this activity, learners discover how a piece of fruit can act as an electrolyte, conducting electricity between two different metals.
