In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

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.

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

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently 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 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, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.

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

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

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.

Learners observe a sealed test tube containing a small amount of solid stearic acid.

In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ
