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 experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

In this physics activity, learners will explore buoyancy.

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.
