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

In this activity (on pages 29-35), learners examine water pollution and filtration.

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 see how many coins they can add to a full glass of water before the water overflows.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

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

In this outdoor water activity, learners explore evaporation by painting with water and tracing puddles. Learners will discover that wet things become dry as the water evaporates.

In this water activity, learners explore how water drops behave on different surfaces.

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 water activity, learners discover ways to move water across the water table.

Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.

Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.

Water treatment on a large scale enables the supply of clean drinking water to communities.

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,

Learners investigate how the temperature of water affects its density.

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.
