Fastest Glacier
http://www.pbs.org/wgbh/nova/teachers/programs/3210_03_nsn.html

NOVA scienceNOW

This video from a 2005 NOVA program features scientists who study the Jakobshavn Isbrae glacier in western Greenland. The glacier is shrinking and moving faster due to increased melting in recent years. The video includes footage of scientists in the field explaining methods and animation of ice sheet dynamics leading to faster glacier movement.

Video length: 7 min.

Teaching Tips

About the Science

  • NOVA scienceNOW correspondent Peter Standring accompanies scientists as they explore the complex dynamics of the massive Jakobshavn glacier in Greenland and try to unravel the mystery of its hurried melting.
  • The location of the Jacobshavn Glacier is not shown in the video.
  • This is a good movie that shows experts in the field, and includes field imagery as well as sketches of processes that are discussed in the video.
  • Comments from expert scientist: The video provides quite a nice review of the basics of glacier motion in Greenland, and some good graphics to illustrate the main processes. I found the language to be clear and easily understandable. Video is out of date (2005) and newer information is needed to provide a complete picture.

About the Pedagogy

  • Additional materials, including questions answered by experts who are featured in the video, are included with video.
  • Transcript provided.
  • Visual learners will enjoy the stunning visuals.
  • Footage of scientists in field and of the methods scientists use can help demystify the research process.

Technical Details/Ease of Use

  • Different levels of resolution are available.
  • Full screen video is grainy.
  • Video may be embedded.

Middle School

Disciplinary Core Ideas: 5

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.

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-ESS3.D1:Human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth’s mean surface temperature (global warming). Reducing the level of climate change and reducing human vulnerability to whatever climate changes do occur depend on the understanding of climate science, engineering capabilities, and other kinds of knowledge, such as understanding of human behavior and on applying that knowledge wisely in decisions and activities.

Systems and System Models

MS-C4.1: Systems may interact with other systems; they may have sub-systems and be a part of larger complex systems.

High School

Disciplinary Core Ideas: 3

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.

HS-ESS2.E1:The many dynamic and delicate feedbacks between the biosphere and other Earth systems cause a continual co-evolution of Earth’s surface and the life that exists on it.

Cross Cutting Concepts: 1

Systems and System Models

HS-C4.2:When investigating or describing a system, the boundaries and initial conditions of the system need to be defined and their inputs and outputs analyzed and described using models.
