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).

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

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