I really can't recommend the actual online webex conference course enough. From someone who isn't easily or often impressed, I have been so impressed with this program.
The material he goes over is awesome. I'd say at least high school physics, but he transforms the technical into non-expert speak. My six year old will watch with interest, big sister gets it on a different level and some of the kids participating were clearly more advanced in physics concepts.
He gets kids and is very funny and engaging. All the kids participating seemed to love it.
