Changing Albedo and Sea Ice
Discuss Sea Ice
- Show students the following video from NASA's Goddard Space Flight Center.
- As the video displays, Arctic sea ice reaches its minimum each September. This graph demonstrates the average monthly Arctic sea ice extent each September since 1979, derived from satellite observations. Review the graph and answer the following questions.
Answer the following questions about the graph.
- Which year has had the lowest recorded Arctic sea ice?
- Which year had the highest recorded Arctic sea ice?
- What is the overall trend in the annual Arctic sea ice minimum?
- What factors might explain the trend in the annual Arctic sea ice minimum?
The Link between Albedo and Sea Ice
Answer the following questions about the short animation.
- What do you notice about the areas of increased solar radiation?
- What do you notice about the areas of decreased sea ice?
- What is the connection between the two images?
Have students summarize the link between albedo and sea ice as an exit ticket.
