Electrical engineers entertain and explain how to construct an electromagnet-driven motor. Kellie and Mike, the hosts of the show, are enthusiastic teachers that will help introduce a project that you likely include in your middle school...

It's time! The fourth lesson in a five-part series has teams of scholars build a circuit for an alarm. A switch lets them turn the alarm on and off and allows them to hide the alarm—just as long as they don't hide it in the classroom!

Students design and build a foam core house which has a light in each room. They demonstrate an understanding of series, parallel, and complex circuits. They complete a worksheet, in complete, sentences expressing these electrical concepts.

In pairs, learners build a piezoelectric generator from readily available electric components in the second and final installment of the two-part series. Tapping the piezoelectric element produces enough electricity to light an LED....

Groups work together to design a lighthouse, from designing and drawing the wiring diagram, to creating prototypes of the switch and circuit, to envisioning and building a scale model along with a blueprint. By including different...

Sometimes, taking things apart is more fun than putting things together. Groups of learners participate in a reverse engineering activity. They dissect a device of their choosing to see how it works—great hands-on learning from the...

Using your knowledge of the flow of electricity, do you think you could build a switch that can complete a circuit to turn on an LED? This site contains the challenge, tips, a lesson plan, and a place for students to document their...

In this electronics science fair project, students will make a simple dimmer switch and investigate the relationship between the resistance in the circuit and the amount of light produced. The Science Buddies project ideas are set up...

This lab will help you understand the physics of vibrating strings, and find out why the tone of an electric guitar changes when you switch between the different pickups. If playing guitars is a hobby of yours, this experiment makes an...

Build a robot and watch how it moves. Activity is designed to help students learn how electrical circuits and switches control how things move.
