Teaching Tips

  • Video could be stopped along the way to have discussion about the graphs embedded in the video. Use NASA NEO website to get current data.
  • Educator might want to bring the topic of self-reinforcing feedback mechanisms into the discussion.

About the Science

  • This video and its accompanying text (http://svs.gsfc.nasa.gov/vis/a000000/a003600/a003619/) demonstrates how, using satellite observations, scientists can monitor changes in the global and regional climate by observing how regions of the Earth's cryosphere shrink and expand.
  • The cryosphere has experienced further changes since 2009. This video remains useful, but educators should seek current data to add to their discussions. For example, here is a 2016 NASA animation about Arctic ice.
  • Comments from expert scientist: The source of the video are NASA satellites so this is a direct view of what has happened to cryosphere over the years, until 2009. It is a kind of direct assessment of the cryospheric changes taking place. The video however, will prove very helpful in educating the people about the changing croysphere and its impact on global climate.

About the Pedagogy

  • Draft of script is provided for students to follow along. Though some of data references are dated, overall trends in different geographic areas continue in the same direction.

Middle School

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.C2:The complex patterns of the changes and the movement of water in the atmosphere, determined by winds, landforms, and ocean temperatures and currents, are major determinants of local weather patterns.

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.

High School

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.
