In this activity, learners explore the different salinities of various sources of water by taste-testing.

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

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

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

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.

Learners conduct a "blind" taste-test of several types of enhanced or fitness water drinking water that has commercially added substances like vitamins, sugars, or herbs.

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.

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

In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through 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.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

Many people get water from a source deep underground, called groundwater.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

Dig a hole, line it, fill it with fresh water, and you have a water hole: a good place to study colonization.

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

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

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 creative roleplay activity, learners will explore the various processes of the water cycle using movement, sound, and props to aid in comprehension.
