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.

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

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

It's much more efficient if everyone knows the relevant terms. Pupils research vocabulary terms related to electric currents to start a unit on solar energy. They then use a multimeter to measure the voltage and current for a solar...

Students investigate the concept of voltage and electricity. They differentiate between an insulator and a conductor in the context of using electrical safety with the help of a doll house. Then students pretend the doll lives in a real...

Students explore electricity by completing a scientific worksheet in class. For this electromagnetism lesson, students discuss the history of magnets and how electromagnets are most commonly used in our daily lives. Students complete a...

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...

Students utilize Internet resources to uncover the pros and cons of two topics in alternative energy technology: photovoltaics and fuel cells. Students analyze the structure and function of each system to make observations about the...
