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

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

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 make their own heat waves in an aquarium.

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

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 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.

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

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