Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.

Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.

Overview and Learning Objectives

Students can toggle charges, and make hydrogen bonds visible or not. The model also displays kinetic energy shading.

This model allows students to heat and cool water, and to see kinetic energy, polarities and hydrogen bonds. It will not allow students to observe the unusual effects on water structure of cooling.

Central Concepts

Key Concept:

Water molecules are small and highly polar. Their polar nature gives water its unusual properties. On a microscopic level, water is a network of these polar molecules linked together by hydrogen bonds.

Water is essential to life. Our cells are largely water, being surrounded in water and using water to transport essential dissolved materials.
