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 explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

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 draw comic-style pictures to show the water cycle. From a starting picture, one learner draws what happens to the water in the next panel, then passes the comic strip to another learner.

In this quick activity about the properties of water (page 1 of PDF under SciGirls Activity: Malformed Frogs), learners will use an eyedropper to slowly place one drop of water at a time onto a penny,

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

Learners see that a carrot slice sinks in fresh water and floats in saltwater.

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 (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star

In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

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 observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

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 experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.
