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

In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea

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

In this activity on page 4 of the PDF (Water in Our World), learners conduct some quick and easy tests to determine the differences between water and other liquids that look very similar to 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.

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

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

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 activity, learners use objects they find on a nature and water to make creative frozen sculptures.

In this activity, learners will engineer a water irrigation system. Learners will create a ditch irrigation system -- or an acequia-- to move water with the help of gravity.

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

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

In this activity, learners make their own "tornado" using two soda bottles and water.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

This activity gives caregivers and their children an opportunity to practice scientific ways of thinking that are developmentally appropriate for early learners.
