We use electricity every day, but the electronics around us largely operate without us being aware of how they do so. The "how" of electronics working is answered by electrical circuits. Electrical circuits allow current to flow through our electronic devices to produce light, sound, and a variety of other effects. Of course, that is an easy statement to make but one that is much harder to explain or demonstrate. That is where classroom projects and lessons come in. When teaching about electrical circuits is included in a student's basic education, they become far more knowledgeable about the world around them. Many who learn about electronic circuits will even go on to a rewarding career in electrical engineering and in using the principles of electric circuitry to improve the world around them. The best way to learn about circuits is through hands-on projects in which circuits are built and used, and there is no shortage of possibilities for these projects.

This full unit plan includes activities, worksheets, and lesson plans for teaching the science of electric circuits.

Use this interactive computer program to build a circuit and demonstrate the flow of electricity. This is good for one-on-one instruction or a group setting.

Students who get the hang of building this simple LED circuit can then take what they have learned and apply it to other instances of circuit-building.

Three Fun Electronics Projects:

Why settle for just one circuit project when this resource features three different circuit projects that are easy to complete? Students can use this page to create a number of touch- and sound-activated lights and other things run by electric power.

A Simple Circuit

This resource is particularly good for younger students, as it helps them to design the simplest circuits that can nevertheless do great things.
