Science lessons from 5-year-olds

I'm eating lunch with a class of kindergarteners. Kaitlin, a tiny blonde, sets down her pizza and tells me something, her face grave. I can't understand a word. As I bend down, she repeats:
"Moons can't see you . . . but they follow you."
"The moon does seem to follow you when you move around," I agree.
"The sun does too," says her neighbor Jada, wanting in on the action.
"The sun is a dying star," announces Adriana from across the table.
DaShawn has a more aesthetic focus, his eyes wide: "It's so pretty!"
