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

Water treatment on a large scale enables the supply of clean drinking water to communities.

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

Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.

Learners explore the variables that affect the properties of ice and the places where different types of ice are found.

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 explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.

In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.

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

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

“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 construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.

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

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