Electrifying STEM: Circuits and Batteries

Required materials:

"switches," wire strippers, insulated wire, flashlight, lightbulbs, batteries, electrical tape


TED-Ed calls batteries a "triumph of science." They allow electronics to operate "without anchoring us to an infernal tangle of power cables." The activities above take learners from simple circuits to an electrifying design challenge.


Scissors may be used instead of wire strippers, but may take extra practice to strip the wire. Select a flashlight that can be easily disassembled so that the lightbulb can be removed. Also, replacing flashlights with lightbulbs may be more cost effective.
