Why is the sky blue?
The sky stays blue for most of the day, but the same sunlight looks dramatically different near dinnertime. Same sun, same air — so where did all that blue go?
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?
