Introduction:
 

If you have an Ipad connect the Ipad to the data projector. Connect to the SATELLITES app. http://www.techrepublic.com/software/satellites-15-mobile/2292645

Another excellent resource to begin is NASA free posters and ppt sessions: ICE http://eospso.gsfc.nasa.gov/eos_homepage/for_educators/eos_posters/index.php

These posters and ppts are free for teachers to use and offer a large amount of background information to become familiar with the topic.

Open with the current satellite data on the screen. Have students identify the International Space Station. Have students define what a satellite is. Ask them what satellites do for humans. Look for answers like communication, weather tracking, send satellite imagery. Ask them how satellite imagery can help us identify glaciers? What data could we collect about glaciers.

Explain the glaciers are a spectacular and important component of the Polar landscape. Most of the world’s glaciers are found near the Polar Regions.

Glaciers exist where, over a period of years, snow remains after summer's end. There is a delicate balance between climatic factors that allows snow to remain beyond the summer season. (Source: USGS). The National Snow and Ice Data Center (NSIDC) maintains an excellent web site with information on glaciers, including facts and figures. According to this resource presently, glaciers occupy about ten percent of the world's total land area and store about 75 percent of the world's freshwater.

Group Size: Whole class
 

Learning Objectives:
 

To understand how remote sensing is used to track glaciers throughout the world.
 

Guiding Question:
 

How do scientists study glaciers?
 

Materials:
 

Lesson at: http://www.polar-remotesensing.alaska.edu/case_glacier/faculty_material.html

Tutorial: http://home.comcast.net/~rhaberlin/glmod.htm
 

Procedures:
 

Explain the conditions of Mendenhall Glacier using the powerpoint provided.

Use the list of references provided in the reading section as background knowledge.

For students use Glacier Power: a resource created for a younger audience that is useful for beginners in glaciology. You can order the free CD or view the resource online

For students to create images to study use: ArcGIS tutorials from ESRI Canada: Tutorials on how to process data and create maps using ESRI's Arc GIS 9.x software package.

Software for glacier digitization for the GLIMS project: Recommended for advanced users.

You may also find the following powerpoint presentation and handout, contributed by Dr. Bruce F. Molnia of US Geological Surveys, useful for introducing glaciers (particularly Alaska glaciers) in the context of climate change and sea level rise.

Assessment:
 

Answer the following questions using the articles in the reference section of Review the articles in the reference section and related articles to answer the following questions: http://www.polar-remotesensing.alaska.edu/case_glacier/faculty_material.html

Are glaciers a good indicator of global climate change? Why do some glaciers retreat while some other glaciers in the proximity advance? Write a review article of remote sensing of glaciers. In the article identify glacial features/phenomena that can be studied using remote sensing techniques. Also discuss the optimal remote sensing data and techniques for studying the respective features/phenomena.

Answer Key or Rubric:
 

Students will create images to track glacial change and create their own mindset of the materials. No "answer key" is needed.
 

Benchmark or Standards:
 

E 5.4D Based on evidence of observable changes in recent history and climate change models, explain the consequences of global temperature changes.
