In this activity, learners build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.

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 investigate how plants use water. By making the flowers change color, learners see how water moves up the stem to the leaves and the flowers.

In this physics activity, learners conduct two experiments to explore free-falling.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

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

This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

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

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

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

In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

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

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 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.
