- Educators may wish to use the video to introduce a discussion about Arctic sea ice. It could also act as an effective summary for such a discussion. Students can compare the data as shown up to 2009 with current information on ice extent.
About the Science
- The points in this video are well-illustrated by satellite images and animations. Shows seasonal as well as annual fluctuations in ice coverage. Good explanation of the ice albedo effect in general terms.
- Comments from expert scientist: It raises concern about the shrinking cryosphere more specifically the northern polar region which is experiencing drastic changes. The data shown here covers time period from 1979 - 2009. The Arctic cryosphere however depicts the similar decreasing trend till now, i.e. 2013.
About the Pedagogy
- The video does a good job of explaining how the extent of Arctic sea ice is changing and what its implications are. While there is no teacher's guide, the video should stimulate a good discussion.
