Students act as engineers to apply what they know about how circuits work in electrical/motorized devices to design their own battery-operated model motor vehicles with specific paramaters. They calculate the work done by the vehicles...

Simulate the movement of a rail gun in this interactive model. Learn how a magnetic field is generated by running electrical current through long rods that accelerates a current-carrying cross-rod.

Investigate the idea of the force between straight current-carrying wires in this magnetic force simulation. See if you can rank the wires from largest to smallest based on the magnitude of their currents.

This simulation demonstrates a rotating conducting disk in a magnetic field which produces a current or a self-exciting dynamo.

Interactive lecture discusses internal resistance which provides help to students in developing an accurate model.

Why do the lights turn on in a room as soon as you flip a switch? Flip the switch and watch the electrons. Does the light turn on immediately? Explain using observations of the model.

This unit provides students the opportunity to explore methods engineers have devised for harnessing sunlight to generate power. Students will initially explore heat transfer and heat storage through the construction, testing, and...

Students learn how engineers design devices that use water to generate electricity by building model water turbines and measuring the resulting current produced in a motor. Students work through the engineering design process to build...

An electrical circuit simulation modeling a resistor, capacitor, and inductor in a series. Vary the resistance, capacitance, inductance and source frequency in the simulation.

Through eight lessons, students are introduced to many facets of dams, including their basic components, the common types (all designed to resist strong forces), their primary benefits (electricity generation, water supply, flood...
