If you put on clothes that were washed in a washing machine, rode in a car, ate food from a fridge, warmed up lunch in a microwave, or played a video game, you used an electric motor. Try this science fair project and you'll learn how to...

Students use potatoes to light an LED clock (or light bulb) as they learn how a battery works in a simple circuit and how chemical energy changes to electrical energy. As they learn more about electrical energy, they better understand...

A telecollaborative project where students communicate engineering concepts across the globe. Student tasks are to deconstruct a common device, then design reassembly instructions for others worldwide to follow to attempt to reconstruct...

Students build their own simple conductivity tester and explore whether given solid materials and solutions are good conductors of electricity.

The lesson will first explore the concept of current in electrical circuits. Current will be defined as the flow of electrons. Photovoltaic (PV) cell properties will then be introduced. This will lead to the principle of "Conservation of...

Students are given a history of electricity and its development into the modern age lifeline upon which we so depend. The methods of power generation are introduced, and further discussion of each technology's pros and cons follows.

Students learn about current electricity and necessary conditions for the existence of an electric current. Students construct a simple electric circuit and a galvanic cell to help them understand voltage, current and resistance.

In the everyday electrical devices we use - calculators, remote controls and cell phones - a voltage source such as a battery is required to close the circuit and operate the device. In this hands-on activity, students use a battery,...

Student teams investigate the properties of electromagnets. They create their own small electromagnet and experiment with ways to change its strength to pick up more paper clips. Students learn about ways that engineers use...

We are surrounded everyday by circuits that utilize "in parallel" and "in series" circuitry. Complicated circuits designed by engineers are made of many simpler parallel and series circuits. In this hands-on activity, students build...

In this hands-on activity, students construct a simple switch and determine what objects and what types of materials can be used to close a switch in a circuit and light a light bulb.

Lesson focuses on how switches control the flow of electricity. Students are posed with the challenge of designing and building a simple switch into an electric circuit.

Students come to understand static electricity by learning about the nature of electric charge, and different methods for charging objects. In a hands-on activity, students induce an electrical charge on various objects, and experiment...

Students learn more about magnetism, and how magnetism and electricity are related in electromagnets. They learn the fundamentals about how simple electric motors and electromagnets work. Students also learn about hybrid...
