"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners build a "pneumatic trough," a laboratory apparatus used for collecting pure gas samples over water.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

Millions of organisms can live in and around a body of water.

In this field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.
