I would have loved for someone to point the numerous events going on for kids all over the world, like NASA summer schools and the like. Your kid is probably a bit young, but if you keep your eyes open, you can find the good stuff in time. As others said, focus away from school sounds good. The nice thing about these activities is that you meet other kids like you (giving you a better frame of reference and tons of awesome friends) and that it's the topic that counts, not how you perform in comparison to the rest of the student body.
