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

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

In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

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.

In this activity learners will explore how water moves on waxed paper. Learners will use science process skills such as using tools and making observations as they explore surface tension.

In this activity, learners make their own heat waves in an aquarium.

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

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.

In this activity, learners will make fish cutouts that propel through the water with the help of surface tension.

In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

In this activity, learners will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.
