Globe Walk, Rob Snyder
Globe Walk, Rob Snyder
IPY STEM Polar Connections
A “Globe Walk” can be used as a demonstration or classroom activity to guide students toward a better understanding of the affects that Earth’s axial tilt, rotation on Earth’s axis, and orbital motion have on the angles of incidence of sunlight, the lengths of daytimes, and solar insolation.
Polar Remote Sensing, Beth Caissie
Polar Remote Sensing, Beth Caissie
IPY STEM Polar Connections
•Satellite sensors specialize in collecting data about specific wavelengths The Geostationary Operational Environment Satellites (GOES) operated by NASA, NOAA, and the U.S. Department of Commerce provide continuous monitoring of weather conditions. Orbiting the Earth’s equatorial plane at a speed exactly matching the planet’s rotation, satellites in the GOES network seem to hover over fixed spots. They monitor atmospheric conditions that lead to hurricanes, flash floods, tornadoes, and hail storms.

Build A Remote Sensing Satellite, Rob Snyder
Build A Remote Sensing Satellite, Rob Snyder
IPY STEM Polar Connections
•Build a model of a remote sensing satellite. •Use your model of a satellite to transform reflected visible of different frequencies into electrical signals with different voltages. •Use different colors of paper to calibrate the model. •Create a model of a landscape using three different colors of paper. •Create a “false color” image of the model of a landscape (if time permits).

Albedo Effects In Polar Regions, Morton Sternheim
Albedo Effects In Polar Regions, Morton Sternheim
IPY STEM Polar Connections
•Why are Polar Regions more affected by global warming than other parts of the globe? •One reason (there are others) is that as sea ice melts and more open water appears, more energy is absorbed, and warming accelerates. •This is a form of positive feedback and it makes the polar climate change faster than the climate in temperate areas. •Increasing vegetation on land also has a similar positive feedback effect.

Atmospheric Co2 And Temperature. What Is Normal?, Beth Caissie, Julie Brigham-Grette
Atmospheric Co2 And Temperature. What Is Normal?, Beth Caissie, Julie Brigham-Grette
IPY STEM Polar Connections
–How much of a change in CO2 concentration and other GHGs is natural? –What is the normal range of CO2 and temperature variability? How is normal defined in this context? –What is the relationship between CO2 and global temperatures?
Caribou, Whales, Andenvironmental Variability, Craig Nicolson
Caribou, Whales, Andenvironmental Variability, Craig Nicolson
IPY STEM Polar Connections
How many caribou are there? Increasing or decreasing? Carrying capacity? How do we measure habitat quality?? Satellite imagery. Whale migration patterns. Activities on caribou and whales. Also, see http://www.nfb.ca/film/being_caribou/ a video entitled Being Caribou..
Polar Literature, Holly Hargraves
Permafrost, Ice Sheets, And Sea Level, Beth Caissie, Julie Brigham-Grette
Permafrost, Ice Sheets, And Sea Level, Beth Caissie, Julie Brigham-Grette
IPY STEM Polar Connections
Sea level rise and inhabited coastlines. Ice shelves and sea ice do not contribute to sea level but they can buttress the land ice sheets from rapid retreat. Causes of Sea Level Rise:
•Melting of glaciers, ice caps, ice sheets •Thermal expansion of sea water ••Small scale changes due to anthropogenic land water storage (damming rivers, over-pumping of water and fuels, wetland and forest destruction) •Relative changes in sea level due to tectonic movements (land subsidence or rebound)
