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

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

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

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

In this activity, high voltage is applied across a pickle to emit a yellow glow. This activity should only be conducted by skilled adults and is best suited as a demonstration.

In this activity about electricity, learners explore what happens when you blow a fuse.

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

Learners build a simple one-cell battery and use an ammeter to measure the flow of current.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

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.

In this activity, learners construct a device out of a piezoelectric igniter, like those used as barbecue lighters.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

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, learners create a tiny electric, motorized dancer. Learners use the interactions of magnetism and electric current to make a wire spin, while displaying the Lorentz Force in action.

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.

In this activity about electricity, learners produce a spark that they can feel, see, and hear. Learners rub a Styrofoam plate with wool to give it an electric charge.

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