In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this activity (on pages 29-35), learners examine water pollution and filtration.

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

In this activity, learners build water-propelled engines from soft drink cans.

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

In this activity, learners create a biosphere in a baggie.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.
