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.

In this experiment, learners float colored ice cubes in hot and cold water.

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 activity, learners investigate convection by using food coloring and water of different temperatures.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

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 determine whether thermal energy can be used for work.

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

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

In this group activity, learners consider environmental conditions—temperature, presence of water, atmosphere, sunlight, and chemical composition—on planets and moons in our solar system to determine

Millions of organisms can live in and around a body of water.
