In this activity, learners see how many coins they can add to a full glass of water before the water overflows.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

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 simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

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 will explore how a hydrometer works by building a working model and conducting experiments.

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 (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

“Exploring the Solar System: Ice Orbs” is a hands-on activity in which visitors investigate a frozen orb, trying to learn about objects hidden inside.
