Electricity – Part 3
Lab began with an introduction to simple, parallel, and series circuits. Then, second grade electrical engineers applied their knowledge of circuits from the previous two labs to create squishy circuits with propellers, buzzers, and switches.

I also demonstrated how to use potatoes and lemons to create a current. Click here to learn more.
