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

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 test which objects float and which sink. Learners discover that objects behave differently in water.

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

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 build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

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 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, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

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 water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

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

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

In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

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 about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.
