I found a sort of silly, but actually very well done, YouTube video on Photosynthesis...some of you might find it a nice change of pace to the computer-generated drone of the textbook animation. It's a bit long, but you can watch it in segments. Enjoy!
I also posted the links to a few other teacher-approved videos in the sidebar. If you find any others that you think are good, send them to me or one of the other bio teachers and we can post them for others to see!
