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

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.

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.

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.

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.

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.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

In this simple activity (on page 7 of the PDF), learners use water and liquid dish detergent to see which one removes lipstick better from an index card.

In this activity, learners investigate how plants use water. By making the flowers change color, learners see how water moves up the stem to the leaves and the flowers.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

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

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 observe the effect of transpiration as water is moved from the ground to the atmosphere.
