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 computer javascripts on many pages that will test students understanding of the material and make the exercises more interactive.
