The questions guide students to think about how these extreme light conditions affect humans and animals living or working there. It also prompts comparisons between Antarctica and equatorial regions, where daylight is more consistent.

This worksheet strengthens students’ understanding of Earth-Sun relationships, reinforcing concepts like seasons and axial tilt. It encourages explanatory writing, as students must form complete-sentence responses based on scientific reasoning. The text helps develop critical thinking by asking students to imagine real challenges faced by scientists and wildlife. It also builds geography and astronomy vocabulary, supporting cross-curricular knowledge.
