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.

This lesson focuses on the states of matter: solids, liquids, and gases. It also discusses the Kinetic Theory of Matter, Thermodynamics, Triple point, Phase Change Graphs and the Heating Curve of Water. It provideds adrawing of a heating...

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...

Interesting activity that discusses many aspects of the energy in a lake, including the evaporation of the water into gas.

Scientific American magazine, in the person of Dr. Gerald R. Van Hecke, gives a wonderfully complete answer to this question. Complete with very many hot words for additional background. And a wonderful NASA launch photo.

Science experiment that demonstrates the four states or phases of matter: solid, liquid, gas, and plasma. Includes full list of materials, procedures, and scientific explanation of how you change water from a liquid state to a gaseous...
