There is a new ning network for Physics, Chemistry and Middle School Physical Science, just launched. We are looking for members and people to help manage the site.
Check it out and join at
Molecular Forces ning. If you'd like to help manage it, please send me a message, we need you! We want to make it as good as
The Synapse (the ning for Biology teachers) which is a great resource.
Also, a new collaborative project for ALL Science educators:
The Science Teacher's Hub wiki (for sharing resources and ideas about teaching Science and integrating ed tech into the Science classroom)
If you have any questions, please reply to the thread. Thanks!
