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

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 (located at the top of the page), learners make an easy river strainer and see what they can catch.

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.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

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

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.
