The website is
www.friendlychemistry.com Several of the games and activities are designed for more than one child but can be "tweaked". The content seems to be fairly comprehensive even if it was used without the activities. The thing that I liked is that it is designed to build on the knowledge of each prior chapter. The concept in chapter 1 is expanded upon in 2, then more so in 3. It was specifically created for 6-8grade students with non-scientific parents so the reading is reasonable.
You can also call them and ask specific questions, they are really nice people. They sent me a PDF of the first 6 lessons to look over.
The entire set is about $100. so in terms of curriculum it's fairly reasonable. I'm going to give it a try.
