Discussion prompts

- 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

- Long bright summer evenings versus dark-by-dinner winter nights
- Opposite seasons in the news — snow somewhere while it's beach weather somewhere else
