This site helps students construct a model of the arrangement of water molecules when present as solid, liquid or gas. Includes background information, lesson plans, links to standards and assessment ideas.

If you look carefully, you could find dozens of similar interesting phenomena that are all linked to the surface tension of water. Here is a project that will help you understand and measure the properties of water surface tension.

Information relating to the properties of water and its behavior.

Realize that there is more in ocean water than just salt. Find out about the salinity of water and how changes in salinity may affect organisms living in the water.

This investigation will help students understand the physical relationships between natural gas, oil, and water in a reservoir and how these relationships can affect recovery.

An exhaustive set of "lecture notes" on various topics in thermal physics (including thermal expansion). Explanations are well done and more interesting than most. Includes both a mathematical and conceptual treatment of topics. Humor,...

A very descriptive site that allows students to understand the different states of matter at the atomic level. Also discusses the process of phase changes and displays phase change graphs. Thermochemistry is also touched upon for high...

Drinking water comes from many different sources, including surface water and groundwater. Environmental engineers analyze the physical properties of groundwater to predict how and where surface contaminants will travel. In this lesson...
