We are lucky to have awesome colleagues at the Center for Biomolecular Modeling in the Milwaukee School of Engineering's. Okay--that's way too much of a mouthful, so call it the CBM, lead by Tim Herman. The CBM group creates models to use as learning tools. They also develop effective teaching strategies that go with the terrific models. http://cbm.msoe.edu
Many of the models listed in SEPGuides under the yellow Molecular Modeling tab feature CBM-MSOE models and SEP versions of their learning activities.
If you want to purchase CBM models or see the teacher resources available, check the 3D Molecular Designs website (3Dmoleculardesigns.com).
