In this activity, learners explore healthy choices related to the liquids they drink. The importance of water and milk as essential nutrients for a healthy body is the focus of the experience.

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

Water treatment on a large scale enables the supply of clean drinking water to communities.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

This is an activity about turbidity, or the amount of sediment suspended in water.

In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.

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

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 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.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

In this activity, learners will make fish cutouts that propel through the water with the help of surface tension.

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

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.

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.

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.
