Canvas Mol is a website that provides 3D, interactive, rotating models of simple and complex molecules. There are 46 models of relatively common molecules like glucose, fructose, and morphine. Each model can be altered to show or not show bonds, to show or not show individual atoms, and to rotate on the X,Y, or Z axis. Canvas Mol works best in Chrome or Opera, but can also be used in Firefox and Safari.

Thanks to Ian Byrd for sharing Canvas Mol with me via email.

Applications for Education
Canvas Mol could be a great resource for chemistry and biology teachers and students. Teachers can manipulate the models to include or not include all parts of the model. Teachers could choose to not display one element of the model and challenge students to identify the molecule.
