Seasons and daylight length

Observe that the length of daylight changes across the seasons, becoming longer or shorter.

The amount of daylight you get is not the same all year long. In summer, the Sun rises early and sets late, giving long, bright days. In winter, the Sun rises later and sets earlier, giving shorter days and longer nights.

This is another sky pattern, just on a much bigger timescale than a single day or a Moon month -- it takes a whole year to go from the longest day to the shortest day and back again.

📋 For the teacher
Teach it (10–15 min):
  • If it is currently a season with an obvious answer, very long or very short days, point it out directly tonight.
  • Compare a memory of a summer evening to a winter evening, if your child can recall both from experience.
  • Reinforce that this is a slow pattern over a whole year, unlike the fast daily sunrise and sunset pattern from week 28.
  • Keep the explanation to simple observation of more or less daylight; the grade-level goal does not require explaining Earth's tilt.
Talk about it:
  • Which season has more daylight: summer or winter?
  • How can you tell if a day has more or less daylight, just from your own routine?
  • Does the amount of daylight ever stay exactly the same, or does it always change through the year?

Mastery looks like: They state that summer days have more daylight than winter days and recognize this as a yearly repeating pattern.

Common stumbles: Confusing temperature (hot or cold) with the separate idea of daylight length; thinking daylight length is the same every day of the year.
