Orbit and States

We were driving to school on Wednesday and Sweet Daughter notices the moon still up in the sky. She says, "Mommy, the moon needs to orbit faster. I shouldn't be able to see it right now. Why isn't it on the other side of the Earth?"

Um... Do I answer her like she's a 2 year old (she is)? Do I answer like she's a kid who just used the word orbit correctly? I don't even remember what my answer was, but these questions are just getting harder. I miss the "what's that?" and "why?" stages... I can't imagine what she's going to ask in a couple more years.

I've also decided the kids need a globe. They have never seen a 3D representation of the earth and yet seem to understand it. They also know 40 states (not the same 40 interestingly enough), and can correctly place them on a map. Some days I feel like I'm not doing enough for them and other days I feel like I must not be doing too badly, if they are picking up this much without me doing very much.
