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

As a group, learners consider sources of water pollution to understand where pollution starts and where it ends up.

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

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

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.

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 estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea

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

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

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

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

Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

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

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

“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.

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