Simple Circuit

Introduction to Circuits

Grades:
7-8
Lesson Number:
2
Description:

This lesson begins with students having hands-on experiences creating electrical circuits using a battery, wires, and a light bulb. Students will learn that electricity is the flow of electrons, and how electricity moves within a circuit.
