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

In this activity, learners will observe laminar and turbulent flow of water using only a plastic bottle, liquid hand soap, food coloring and water.

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, learners will simulate the processes of the water cycle at home in a plastic sandwich bag.

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 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

In this activity, learners see how many coins they can add to a full glass of water before the water overflows.

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

Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

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.

Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

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.

In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

In this activity (on page 2 of PDF), learners mix oil and water. Then, they add soap and observe what changes! The activity demonstrates how oil and water don't mix, except when soap is added.

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 activity, learners get a closer look at the shape of a drop of water and a drop of oil. Learners first drip water onto wax paper and examine the shape of separate drops from a side view.

Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold 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 weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.
