After investigating different electrode/electrolyte combinations, we began a discussion about building our battery. The goal will be to have enough cells in our battery to power a LED.

This share & compare exercise was an excellent way to discuss in context, magnitude, electric potential, and connecting with our prior class investigation, building an incandescent lightbulb.

I’m very excited to see how the students do making their battery next class.img_1091 img_1113
