- 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 sea ice has been continuing this similar decreasing trend.
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.

Disciplinary Core Ideas: 5
MS-ESS2.C1:Water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization, and precipitation, as well as downhill flows on land.
MS-ESS2.C3:Global movements of water and its changes in form are propelled by sunlight and gravity.
MS-ESS2.C4:Variations in density due to variations in temperature and salinity drive a global pattern of interconnected ocean currents.
MS-ESS2.D1:Weather and climate are influenced by interactions involving sunlight, the ocean, the atmosphere, ice, landforms, and living things. These interactions vary with latitude, altitude, and local and regional geography, all of which can affect oceanic and atmospheric flow patterns.
MS-ESS2.D3:The ocean exerts a major influence on weather and climate by absorbing energy from the sun, releasing it over time, and globally redistributing it through ocean currents.
Disciplinary Core Ideas: 2
HS-ESS2.C1:The abundance of liquid water on Earth’s surface and its unique combination of physical and chemical properties are central to the planet’s dynamics. These properties include water’s exceptional capacity to absorb, store, and release large amounts of energy, transmit sunlight, expand upon freezing, dissolve and transport materials, and lower the viscosities and melting points of rocks.
HS-ESS2.D1:The foundation for Earth’s global climate systems is the electromagnetic radiation from the sun, as well as its reflection, absorption, storage, and redistribution among the atmosphere, ocean, and land systems, and this energy’s re-radiation into space.
