searching for science labs

Hi

I'm a graduate student at the Harvard School of Ed. A colleague and I have grant money to develop a web site that would provide a shared space for teachers to share science labs and review and/or rate science labs for their fellow teachers. We' ve heard it is challenging to find useful science labs via the web.

Can you tell me --
1. Where do you go to find new science labs?

2. What are your favorite web sites for finding science labs, or do you just Google for them?

3. How would you like to search for science labs in a database -- by grade? by state standard? by topic? other?

5. Lastly, if you used such a site and found it useful, would you be willing to write a short (3 sentence) review of a lab you got from the site? what would encourage you do write a review? (a raffle or prize? recognition in some way of your contribution to the site? other ideas?)

Thanks so much for any advice you can give us on this project!
