Sorry for the late reply,
If they do end up experimenting with Scratch, the projects I taught at Oakland's video game museum might be interesting or useful. They were all designed to be teachable in an hour and a half, and a lot of them have empty templates next to the finished product, like they did in old cooking shows, before cooking shows got feisty.
Don't be too surprised if they jump from code thing to code thing really quickly! It's like anything, we evaluate our interests as we go. Scratch's limitations might not suit them after a while, and then there's a whole other universe of alternatives. Happy hacking!
