Current transfers energy around circuits. Circuit components have various properties that can be measured and then used to make circuits for control and also circuits for testing other components.

This lesson focuses on electric charges. Electric current is the flow of electric charge. Some insulating materials become electrically charged when they are rubbed together. A substance that gains electrons becomes negatively charged,...

This lesson focuses on Electrical circuits including standard symbols for electrical components, a list of components and what they do, a discussion of various types of resistors, and alternating current and direct current. Links to a...

In this activity, students will understand that electricity moves through different circuits and discover what types of materials are conductors and insulators.

Hunkin's Experiments is a group of simple cartoon illustrations of scientific principles. Some would work well in the classroom, but others have little value beyond entertaining students. All of the projects are easy to do. These...

This lesson provides an interactive activity on electrical circuits along with a information sheet and a practice test.

This lab was designed to have students test the factors that determine how much current is induced in a circuit when area of the circuit is changed. This lab is a quantitive lab that supplements the lab on magnetic flux.

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...

Using plastic straws, wire, batteries and iron nails, student teams build and test two versions of electromagnets-one with and one without an iron nail at its core. They test each magnet's ability pick up loose staples, which reveals the...

This lesson explains how a DC electric motor works including a diagram and description and links to a video and a test.

Students build a saltwater circuit, which is an electrical circuit that uses saltwater as part of the circuit. Students investigate the conductivity of saltwater, and develop an understanding of how the amount of salt in a solution...

This lab was designed to have students test the factors that affect the acceleration of a metal bar that is carrying a current through a magnetic field.

A step-by-step guide to build a wind turbine. Using their wind turbine, students test how much energy is created by using a variety of wind blades and wind speeds.

A site dedicated to help students prepare for the AP Physics B test. This specific site reviews circuits including current, resistance, power, Ohm's law, batteries, DC circuits, transformers, and car coils. Site contains links to video...

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...
