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.

In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

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 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.

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 astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

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.

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 outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

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.
