Learners construct an electricity-generating wind turbine out of a plastic bottle.

In this activity, learners explore the relationship between electric charges and magnetic fields.

In this activity, you'll make an electric motor--a simple version of the electric motors found in toys, tools, and appliances everywhere.

In this activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.

This is a series of demonstrations about different electrical and magnetic phenomena.

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

Learners use compasses to detect the magnetic field created by current moving through a wire. This is one of four activities learners can complete related to PhysicsQuest 2008.

Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.

In this activity related to magnetism and electricity, learners observe as two parallel, current-carrying wires exert forces on each other.

Learners drop a magnet through a coil of wire to create electric current in a circuit. LEDs in the circuit allow learners to detect the direction of current flow.

Learners use the current flowing in a wire to create a magnetic field that turns a magnet. Learners can use this property of electromagnetism to build a magnet-powered pinwheel.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this activity, learners use a nail and magnet wire to build an electromagnet, which controls the movements of a paper dancer.

In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field.

In this activity about electricity and magnetism, learners discover how a doorbell works. A coil of wire with current flowing through it forms an electromagnet that acts similar to a bar magnet.

In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging.

In this activity, learners explore how an electromagnet works by making a simple one. Using this knowledge, learners design a diagram to make a working speaker using household materials.

In this activity, learners build an electromagnet using a nail, a cork, a battery, and electrical wire. Use this activity to demonstrate how electric currents produce magnet fields.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.
