In this activity from the MysteryScience blog, 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.
