The teacher seems like he might be a geek, and all the kids are highly gifted so he is probably used to some odd projects. But I don't know if she wants to do it anyway. I showed her the book and she said "no way am I going to stick a battery on my tongue." Of course that's like 1 project out of the whole book but now she's turned off by the book.
Someone suggested Sketch Up on another thread (thank you!) so I downloaded it and she seems to like it. Seems like it's good for teaching geometry concepts. Not sure what "project" she can do with that but she likes the idea.
