Check understanding

  • Describe the pattern: more daylight hours in summer, fewer in winter
  • Compare sunrise/sunset times at different points in the year
  • Relate amount of daylight to seasonal changes in weather and nature
“Has your child noticed that it's still light at bedtime in summer but dark much earlier in winter, and can they explain this pattern?”
