In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.

In this fun gardening activity, learners discover their soil type. There are three basic soil types: sand, silt, and clay.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

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

Learners design their own experiment to determine which M&M color dissolves the fastest in water.

How many colors make black? Gather as many water soluble black markers as you can find.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

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

In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

This is an activity about turbidity, or the amount of sediment suspended in water.

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 physics activity, learners will explore the concept of buoyancy, especially as it relates to density.
