In this multi-part activity learners examine non-point water pollution.

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

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

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

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

In this activity, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

This activity (located on page 8 of the PDF) introduces learners to the concept of Non-point Source Pollution--what happens when rain washes garbage and other pollutants into rivers and lakes.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

This activity offers learners and their families several ways to raise their awareness together about home water.

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

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

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

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 activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

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

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.
