The Topic: 
Glaciers

Easier - Glaciers are rivers of ice that move very slowly. They can take a year to move as far as you can walk in a few minutes. When a piece of a glacier breaks off and floats in the water, it's called an iceberg.
 
Harder - Glaciers form high in mountain valleys (valley glaciers) and in polar regions (continental glaciers) where the snow falls but never melts. The heavy snow crushes the layers below and forms a mountain of ice. As the glacier moves slowly down the mountain, it grinds against the ground and the walls of the valley to make it deep and wide. Glaciers cover about six million square miles which is about three percent of the earth's surface.
 
 
All About Glaciers (National Snow and Ice Data Center
http://www-nsidc.colorado.edu/glaciers/
What is a glacier? How is a glacier formed? Why do glaciers move? What are the components of a glacier? Where are glaciers located? What types of glaciers are there? How do glaciers affect the land, people? Are glaciers dangerous? How do glaciers reflect climate change?
 
Charlotte, The Vermont Whale: Glaciers and the Glacial Ages 
http://www.uvm.edu/whale/GlaciersGlacialAges.html
What are glaciers? How do they form? What are the physical effects of glaciers? Can these effects be seen here in Vermont? How frequently do Ice Ages occur? When did the last glacial age end? Will glaciers again advance over North America?

Using the websites, complete one or more of the following activities:
 
Select a role and use the links below to solve the problem or create a project.
 
Glacier Artist. You're an artist exploring the beauty of glaciers. Create a picture showing how a glacial area might change over millions of years. Create the picture as a series of panels like a cartoon.
 
Glacier Forecaster. You're a weather forecaster trying to predict the next ice age. Based on information about past ice ages, global climate, and other factors, create a chart showing the past, present, and future of glaciers.
 
Glacier Reporter. Write about what you think it might be like to live near a glacier. Read personal experiences on The Glacier Homepage. Locate a school near a glacier. Interview a student there via email to find out what it's like to live near a glacier. Use the Web66: International School Web Site Registry to locate a school on the Internet. Compare your original ideas with the interview results.
 
Glaciologist. There are many types of glaciers. Use the All About Glaciers (National Snow and Ice Data Center) to explore each type. Create a pretend island off the coast of Greenland. Give the island a name, and create a wall chart showing each type of glacier. Create 'flip card' labels that describe each glacier.
 
In the News. Read articles about Glacier News and Glaciers in the News. Take one of the news stories and create a short news video. http://ak.water.usgs.gov/glaciology/news/
 
Glacier Photographer. Copy one of the pictures from the Glacier Image Database into a word processor. Write a story about an adventure set on the glacier. Be sure to use the science of glaciers in your story.
 
Junior Glaciologist. After learning all about glaciers, find out more by submitting a question to a glaciologist at the Glaciers in the News site.
