Why is it hot in summer and cold in winter?

Noon shadows: your shadow is long and the sun rides low across the sky in winter, short with a high overhead sun in summer — same body, same stick, different season. Plus long bright summer evenings vs dark-by-dinner winter.

Talk about it

  • Guess what makes summer hot before we run it — is it distance or the lean?
  • When it's summer here, what season is it for kids in Australia, and why?
  • Next sunny noon, let's check your shadow — is the sun riding high or low today?
