Students study the concept of electricity, what an electric current is and its relationship between voltage and resistance.In this electrical instructional activity students solve problems using Ohm's law, and research alternative...

Students explore concept of current in electrical circuits. They examine how energy from the sun can be used to power everyday items, including vehicles.

Give me a home where electric buffalo roam and I'll show you an ohm on the range. Introduction your classes to potential and kinetic energy, electricity, and renewable resources with a resource that combines observation, direct...

Compare the drift speed of conduction electrons in a current-carrying wire to the signal speed of changes in current. They also distinguish between DC and AC and describe how AC is converted to DC.

Eighth graders discuss series and parallel circuits and design an investigation to test a hypothesis on total resistance of series and parallel circuits in combination. After discussion, groups design their experiments, run tests, and...
