Positives

• Students can work at their own pace through this self-guided textbook lesson, interacting with useful questions throughout.
• Figures and graphics are included to illustrate the text.
• Students can check their understanding by taking an interactive quiz at the end of the lesson.

Additional Prerequisites

• Students must sign in to access some interactive features.
• The video at the end of the lesson is an audio file with just one image of polar bears accompanying the audio. Some students may have a hard time focusing on just listening to the audio, so turning on subtitles may help.

Differentiation

• In biology classes, students could choose a plant or animal that lives in a polar region and make a slideshow presentation to explain how the organism survives in such extreme conditions.
• Students could use this interactive data resource from NASA to learn how climate change is affecting ice sheets in polar regions.
