I recently found this Livebinder of Physics Resources. It has resources, lesson materials and activities, links, and more, all organized by Physics units and topics.
It is well organized with some great resources including video clips from the Mythbusters and other fun resources, simulations, and virtual labs.
It is a great resource for teachers or students, especially for a beginning teacher looking for some help getting their lessons organized and finding resources.
