During the lesson, students will learn about series and parallel circuits and how they are used for different purposes. If students do not have access to Snap Circuits, this lesson can be completed using safe household materials that provide students the ability to connect the following components: Power source ( 9V battery); Conductive material (wires, aluminum foil, paper clips, etc.); An “output” device for the electricity (flashlight lightbulb or holiday light); A switch (two metal thumbtacks and a paper clip, aluminum foil and a paper clip, etc.).
