Texas Instruments: Freezing and Melting of Water
Freezing temperature, the temperature at which a substance turns from liquid to solid, and melting temperature, the temperature at which a substance turns from a solid to a liquid, are characteristic physical properties. In this...
Science Struck
Science Struck: An in Depth Comparison of Cohesion vs. Adhesion
Explains what cohesion and adhesion are; what their effects are in a liquid; what surface tension, a meniscus, and capillary action are; and gives examples of where one can observe cohesion and adhesion.

King's Centre for Visualization in Science: Scientific Models
A series of interactive applets use scientific models to teach some basic concepts of matter, including states of matter and physical and chemical changes.
Carnegie Mellon University
Chem Collective: Brownian Motion
Particulate level simulations that show only solute particles are convenient, since they focus student attention on the molecules of most interest. However, such solute molecules move in a Brownian manner. This simulation helps students...
