Lesson Focus
Lesson focuses on the concept of electron flow through the demonstration of electrical circuits in a flashlight, and how batteries operate.
Lesson Synopsis
The Flashlights and Batteries activity explores how a flashlight works, showing the electric circuit and switch functions of this everyday household item. Students learn how batteries work, how they provide power to the simple circuit within a simple flashlight, and how the switch controls the flow of electrons. Students disassemble a flashlight, and draw a schematic of a flashlight's circuit design.
Age Levels: 8-11
Objectives
- Learn how switches control the flow of electricity.
