EXPLAIN IT WITH MOLECULES

Just as the 20th century was marked by the development of electricity, telephones, aviation, computing, and private motor vehicles, the 21st century is being marked by significant progress in a broad spectrum of technologies, among them: molecular computing, genomics, rational drug design, and alternative energy.

What is common to all these new technologies? They are all being made possible because of a greater understanding of The World of Molecules.

Many questions that arise in K-12 education can be better understood by seeing and interacting with molecules in 3-D.

Explain it with Molecules -- Interactive Molecules-- is about "real interactivity"! All you need is to be java enabled. The JMol Applet used with these molecular structures will allow you to view molecular structures in 3-D. Images can be viewed as wire-frame, ball and stick or CPK. As with the Chime plug-in, it is also possible to measure distances and angles.

We have also included javascripts on many pages that will test students understanding of the material and make the exercises more interactive.

 

WATER --- Why is water such a good solvent?

ICE --- Why does ice float?

METHANE --- What is the geometry of methane?

CARBON MONOXIDE --Why is carbon monoxide so dangerous?

SOAP --- How does soap work?

GRAPHITE -- Why is graphite so soft if it is made of only carbon?

DIAMOND --- Why is diamond so hard if it is made of the same substance as graphite?

FULLERENE -- Why is the fullerene and similar structures the cornerstone of nanotechnology? How big is a nanotube?

SALT -- NaCl -- Why does table salt have a cubic crystal shape?

DNA STRAND -- Why do carcinogens cause cancer?
