Discussion prompts

  • Predict: if Earth had no tilt at all, what would the seasons be like?
  • Predict: we're closest to the sun in January — so why isn't January the hottest up north?
  • Predict before we test: does the same light warm a small bullseye patch or a wide smear more per spot?

Where it shows up in real life

  • Your long, low shadow at winter noon versus your short shadow in summer
  • Long bright summer evenings versus dark-by-dinner winter nights
  • Opposite seasons in the news — snow somewhere while it's beach weather somewhere else
