Why is the sky blue (and sunsets red)?

A real sunset out the car/bedroom window: "the sky was blue all day, then the sun got fat and orange at dinnertime — same air, where did the blue go?" Pairs with summer evenings and the long golden light before bed.

Talk about it

  • Before sunset tonight, guess what color the sun will turn — then watch and see if you were right.
  • The sky is blue all day, then the sun goes orange at dinner. The air didn't change — so where did the blue go?
  • If the Moon has no air, what color do you think its sky is at noon?
