Frozen Earth


This video montage of spectacular NASA satellite images set to music shows different types of ice and ice features as well as descriptions of satellite-based measurements of ice cover. Text captioning describes how global ice cover is changing, and how this is measured.

Video length: 4:59 min.

Teaching Tips

  • The sound is basically just music, so it can be turned off and the video can be used like an automated PowerPoint presentation; it would work well with teacher-provided lecture content.
  • The animated graph of Arctic ice minima is compelling and important, but underplayed in the video - it is only shown briefly. So instructors may want to stop the video to talk about it.

About the Science

  • NASA satellite imagery of different types of natural ice on Earth (glaciers, sea ice, mountain snow/ice cover, etc.).
  • Animations of global ice cover and of the varied NASA satellites that track ice cover.
  • Comment from expert scientist: It broadly covers the different "forms" of ice found on the planet. Visually stimulating.

About the Pedagogy

  • Uses engaging NASA images of all types of ice features.
  • Some of the imagery is false color, which is not explained; teachers will have to do some homework to field students' questions about these pictures. Some others (like blue ice glacier calving fragments) are natural color and are also not explained or highlighted. Teachers will want to review the video before using to be certain they know what kinds of images are being presented.

Technical Details/Ease of Use

  • Images are beautiful and of high quality.

Middle School

Disciplinary Core Ideas: 2

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-PS4.B1:When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object’s material and the frequency (color) of the light.

High School

Disciplinary Core Ideas: 3

HS-ESS1.B2:Cyclical changes in the shape of Earth’s orbit around the sun, together with changes in the tilt of the planet’s axis of rotation, both occurring over hundreds of thousands of years, have altered the intensity and distribution of sunlight falling on the earth. These phenomena cause a cycle of ice ages and other gradual climate changes.

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.

HS-ESS2.D4:Current models predict that, although future regional climate changes will be complex and varied, average global temperatures will continue to rise. The outcomes predicted by global climate models strongly depend on the amounts of human-generated greenhouse gases added to the atmosphere each year and by the ways in which these gases are absorbed by the ocean and biosphere.
