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.

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.

In this activity, learners add different liquids to water and apply their working definition of “dissolving” to their observations.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

In this activity, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

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 simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

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

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

Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.

In this activity, learners explore how salt water freezes in comparison to fresh water.

How many colors make black? Gather as many water soluble black markers as you can find.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.
