Provides students, teachers and researchers the basic concepts in mathematics and their connection to molecular modeling. Links


Biomolecular Explorer 3D

Designed to give high school biology teachers easy access to interactive 3D structures of biologically significant 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 computer javascripts on many pages that will test students understanding of the material and make the exercises more interactive.
