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

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

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

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

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

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 biosphere in a baggie.

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

This activity gives caregivers and their children an opportunity to practice scientific ways of thinking that are developmentally appropriate for early learners.

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

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.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

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

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

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

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

“Exploring Earth: Investigating Clouds” is a hands-on activity in which visitors create a cloud in a bottle and explore it with laser light.

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.
