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 explore the relationship between electric charges and magnetic fields.

In this activity, learners build simple alarms that they can attach to anything, such as a drawer or doorway. This activity introduces learners to electricity, circuits, and currents.

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, 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.
