Electrical Energy
4-PS3-2, 4-PS3-4, 3-5-ETS1-1, 3-5-ETS1-3
In this lesson, students are introduced to electricity as a form of energy. In the activity, Build a Flashlight, students investigate how electrical energy requires a circuit and make their own mini flashlights from LEDs, button batteries, and strips of aluminum foil. Along the way, they’ll learn about the anatomy of a battery, begin to see how circuits work, and discover how handy an on-off switch can be.
