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 experiment is designed to illustrate how fluids, including water, have the ability to flow.

This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.

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, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

Learners gain an intuitive knowledge of the physical aspects of watersheds by creating their own watershed models.

“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.

Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.
