Antarctica: Twilight zone

What causes the length of day and night to change in the Twilight Zone?

This extended resource is designed for Year 7 Earth and Space students who are learning about daylight hours. It covers the changing seasons, location and latitude, climate and more. You will find starter and plenary activities, practical investigation guides, suggested solutions and students worksheets, all mapped to the curriculum and themed around Antarctica.

In this sequence of learning, students will find out about the significant variation in sunlight hours that occur across Antarctica in comparison to other locations on Earth. They will interpret graphs of daylight hours and compare hours of daylight and darkness received by places at different locations across Antarctica, Australia and the world. Students will investigate the relationship between a locality, the hours of daylight it receives and its temperature range. They will also investigate the reasons for variability of sea ice coverage around Antarctica and find out what causes the changes in seasons across Earth.
