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.

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

This experiment describes how to create a "dribble bottle" which only leaks water when the cap is unscrewed. The full water bottle has a small hole made with a push pin.

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.

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,

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 activity, learners explore why frost forms. They create their own frost using a solution of ice water and salt in a glass.

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.

In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.

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 explore gravity and air pressure as they experiment with holding a glass full of water upside down, without spilling it, using a simple piece of cardstock.

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