In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.

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 simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

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 activity, learners explore the concept of conducting or insulating electricity.

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.
