I participated in a free "Teleclass" yesterday with DS7 on Supercharged science. As part of a chemistry experiment, my DS got to make glow in the dark slime. He had the best time. It was a great class in that Aurora (the instructor) takes the time to explain why things happen the way they do. She also stayed on the call after class until every single question was answered. I was really impressed.
They have a special offer up right now on their "E-Science" program for $1.00 for the first 30 days. We signed up and my DS is so excited. I'm looking forward to seeing how it goes. The sites philosophy is to make kids crazy excited with science through projects and experiments, then introduce the text to answer the "whys" of what happened.
At the end of the 30 day trial, the program costs $27.00 a month. I'll keep you posted as to how it goes.
