Midnight Sun & Polar Night
极昼与极夜
Description
Know that at the poles, daylight and darkness are extreme — in summer the Sun never fully sets (midnight sun) and in winter the Sun never rises (polar night lasting months) — and that this is very different from what we experience at home, where every day has both daylight and darkness
Mastery Evidence
- Describe midnight sun: in polar summer, the Sun stays above the horizon all day and night
- Describe polar night: in polar winter, the Sun stays below the horizon for weeks or months
- Compare this to normal day-night patterns at home, noting the dramatic difference
Assessment Prompt
Does your child know the amazing fact that at the poles, the Sun doesn't set at all in summer and doesn't rise at all in winter — so there can be months of daylight or months of darkness?
