In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

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 will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

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

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

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 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 outdoor water activity, learners explore evaporation by painting with water and tracing puddles. Learners will discover that wet things become dry as the water evaporates.

In this activity, learners create their own icons for a forecast-at-a-glance poster for their classroom/learning space.

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.

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

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

In this activity, learners explore a bucket of sand and beach objects.

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.
