Wind Power
How do engineers turn something that is readily available, like wind, into energy? Scholars create a prototype of a wind turbine and attach it to a motor. They test out their prototypes and decide on their effectiveness. They also...
Curated OER
Solar Photovoltaic (PV) Kit
The National Energy Foundation presents this activity, which instructs students to follow directions to connect a solar electric panel to a buzzer. They charge the solar panel to cause the buzzer to sound. The process is repeated with a...

Let's Make a Solar Car
Learners transform a car that they have built out of K'NEX into a solar car. Students add one or two solar cells to the car to power a DC motor then connect the motor to the car and come up with a method to drive the car. This is the...
Curated OER
Current Thinking About Magnets
Learners construct their own magnet and wire device. In this inquiry lesson, students investigate the factors affecting the strength of magnetic forces. They manipulate different variable to determine their effect.
Curated OER
Swamp Thing
Students create a build-it-yourself boat that runs on two small electric motors. Swamp Thing has an electronic brain that can be controlled and steered with a flashlight.
Curated OER
Construction of an Ammeter and a Voltmeter from a Galvanometer
Students explore series and parallel circuits. In this physics lesson, students construct a simple circuit and measure its maximum current. They construct their own voltmeter and ammeter that operates at a specified range.
