Students make a circuit on a mystery card. They then use an electrical tester to determine where electricity flows between circles on the card. They will connect wires, bulbs, and a battery to form an electrical tester.

Learners test their knowledge of electrical conductors and circuits by constructing an electric tester and using it to determine where electricity flows between circles on a mystery card.

Students participate in an online lesson to explain the conductivity of different materials and the effect of changing the power source.

Build circuits with resistors, light bulbs, batteries, and switches. Take measurements with the realistic ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a life-like view.

Explore the origin of energy bands in crystals of atoms. The structure of these bands determines how materials conduct electricity. Java required.

Play hockey with electric charges. Place charges on the ice, then hit start to try to get the puck in the goal. View the electric field. Trace the puck's motion. Make the game harder by placing walls in front of the goal. This is a clone...

Play ball! Add charges to the Field of Dreams and see how they react to the electric field. Turn on a background electric field and adjust the direction and magnitude. (Kevin Costner not included). Java required.

At this site from California Energy Commission, you can learn more about electricity safety with this coloring book. Teach children how to use electricity safely.

The nature of insulators is described at the atomic level. Band gap theory is used to explain what distinguishes insulators from conductors.

Read about the device used for measuring resistance in a circuit which was discovered in 1843, but had been invented a decade earlier. The inventor's name was not Wheatstone.

In the modern world, virtually everyone is familiar with electricity as an accessible, essential form of energy. In electricity's earlier days, scientists used the buildup and release of static electricity.

William Gilbert was an English physician and natural philosopher who wrote a six-volume treatise that compiled all of the information regarding magnetism and electricity known at the time. The work included descriptions of many of...

William Thomson, known as Lord Kelvin, was one of the most eminent scientists of the nineteenth century and is best known today for inventing the international system of absolute temperature that bears his name. He made contributions to...
