Allianz Tower and Molecule Man (Berlin)

Atomic Force Microscopy (AFM) method used to get an image of the first molecule -- a pentacene structure -- in Switzerland, 2009.

This is a computer generated 3D image of a carbon monoxide molecule. Carbon monoxide contains one carbon atom and one oxygen atom. It is an odorless gas that is highly toxic to humans.

This diagram shows a 3D computer generated image of the triatomic molecule known as ozone. Ozone is an allotrope that contains three oxygen atoms. The ozone layer found in the upper atmosphere helps protect the Earth against potentially...

Benzene animation, showing some vibrational modes.

Problem sets, tutorials, and activities related to biochemistry.

Gives information on Kekule's most important discovery -- benzene.

A great page for all around biochemistry and background information. Includes the molecular structure and most of the information relevant to its role in living cells.

Here are instructions for a simple demonstration showing how sound waves are passed from one molecule to another. Using only marbles, this experiment "mimics the way a sounds wave is produced."

This diagram shows the chemical structure of methane. A methane molecule contains one carbon atom and four hydrogen atoms.

This site gives a good explanation of osmosis and reverse osmosis. Also includes a scientific diagram of the process.
