Satellite Observations of Arctic Change

Satellite imagery gives students, teachers, and professional researchers access to lots of information to analyze and interpret. Through timelapses of satellite imagery students can see how landscapes and seascapes change over time. Some timelapses of satellite imagery can be found in Google Earth. The National Snow & Ice Data Center at the University of Colorado Boulder also offers some excellent timelapses based on satellite observations.

Satellite Observations of Arctic Change is a set of eight timelapse maps. Each of the maps shows representations of changes based on information collected via satellite imagery. The maps included in the set are:

  • Frozen Ground
  • Sea Ice
  • Sea Ice Average
  • Water Vapor
  • Snow Cover
  • Vegetation
  • Near-surface Air Temperatures
  • Annual Minimum Exposed Snow and Ice
Applications for Education
Satellite Observations of Arctic Change could be a useful set of maps to use in a lesson on climate change. The maps alone don't explain what caused changes. The assignment for students to complete is to research the factors contributing to the changes.

Free Technology For Teachers: SkyServer- Space Exploration Website

The Sloan Digital Sky Survey better known as the SkyServer is a rich website full of images from throughout the galaxy and beyond. The SkyServer aims to, in their words, "build the largest map in the history of the world." The project is supported by NASA, the US Department of Energy, and National Science Foundation, and the Alfred P. Sloan Foundation. The galleries of famous places is one of the world's most extensive public galleries of space imagery. To date over 50 million images have been captured. The famous places gallery is a nice resource to use in conjunction with the Celestia space exploration simulator.

Applications for Educators
The SkyServer has a teachers section with an extensive list of lesson plans and materials appropriate for students i
n the upper elementary grades through high school. The "kids" section has information and activities students can access and learn from intuitively.
The image on the left came from the section on "famous places." The famous places section is a great place to visit in conjunction with a space explorer simulation like Celestia that I reviewed on Sunday.
