In this activity, learners will simulate the processes of the water cycle at home in a plastic sandwich bag.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

In this activity, learners will explore the water cycle by creating a small atmosphere.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

In this activity, learners make their own "tornado" using two soda bottles and water.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this activity, learners create a biosphere in a baggie.

In this activity, learners model atmospheric convection currents using food coloring, water, and clear cups. Activity includes step-by-step instructions, STEM connections, and more.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.

This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

In this activity, learners will explore how density is affected by temperature and how that can create currents.

In this activity, learners will pretend to be archaeologist using this chilling experience.

In this activity, learners will create a magnifying glass called a waterscope, using water and household items, to examine various objects.
