My DS uses
www.superchargedscience.com as part of his curriculum. They use teleseminars along with viedeos for many of the units. It has worked well for us and is something to consider failing having access to full live access. Some of the video conferencing software could probably be adapted to a classroom setting. The other thing I like about this program is the speed with which they respond to e-mailed questions as it's important to get an answer while the child is still interested in the subject.
