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

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.

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.

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

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,

In this activity about water's cohesive and adhesive properties and why water molecules are attracted to each other, learners test if objects repel or absorb water.

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 three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.

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 about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

This is a simple and fun activity for learners to explore water and colors.

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

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.

This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).
