In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this water activity, learners discover ways to move water across the water table.

In this activity, learners explore why frost forms. They create their own frost using a solution of ice water and salt in a glass.

In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.

In this activity, learners will engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.

As a group, learners consider sources of water pollution to understand where pollution starts and where it ends up.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.

In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.
