Readers of this journal article can learn about data sent back to Earth by NASA's Lunar Prospector spacecraft, which indicates the presence of water in the form of ice at the Moon's north and south poles. Materials presented include an estimate of how much water exists, where and in what form it might occur, and what its economic value as a resource for human exploration might be. Full description.

In this lesson, students learn about the causes and effects of the melting ice formations in Antarctica. They are directed to examine the causes and effects of melting ice shelves and perform an experiment to learn how melting ice affects water levels. As part of an associated activity, students research different aspects of the topic and create a news special. Objectives, a materials list, procedures, ... Full description.

Using the European Space Agency's Infrared Space Observatory, Spanish and Italian astronomers have for the first time measured the total amount of water in cold regions of the Milky Way. The findings and implications of this research are discussed here, with emphasis on the fact that water is abundant in these cold regions and exists mostly in the form of ice. Images and videos are included. Full description.

Visitors can study this account of the calving of the Larsen ice shelf and the disintegration of the ice shelf around James Ross Island that occured in Austral Summer of 1994-95. The account is in chronolgical order and is accompanied by photographs. Follow-up examinations from 1996-2002 and links to related material are provided. Full description.

This is a copy of a news story originally written on March 1, 2001 that describes the theory of how small comets may have been at least part of the source of the water on our planet. The site also offers links to the University of Iowa's Small Comets research site and information on the ground-based measurements that are used to identify these comets. Full description.

This site describes how snow and ice runoff become surface water and emphasizes how runoff from snowmelt is a major component of the global movement of water. A hydrograph from the U.S. Geological Survey shows a four-year time series of streamflow and illustrates how runoff from snowmelt affects the daily mean values, particularly at certain times of the year.

In this lesson, students learn about meteors, meteorites, and comets by reading and discussing a related New York Times article about the Leonid meteor showers and the methods that scientists are using to learn from these meteors. Students then create and observe a comet in their classroom. Full description.

This site contains an extensive list of frequently asked questions and short answers regarding the characteristics of icebergs. In addition, there are links to detailed descriptions of the six main types of icebergs, other interesting facts about icebergs, and photographs of Newfoundland icebergs. Full description.

The International Ice Patrol is a branch of the United States Coast Guard. They monitor iceberg danger near the Grand Banks of Newfoundland, and provide the limits of all known ice to the maritime community. This kids page provides an illustrated story of the life cycle of icebergs, as well as a list of questions and answers about icebergs in general. There is also a set of links to other sites that ... Full description.

This site contains information about snow, glaciers, permafrost, sea ice and cryospheric trends. The cryosphere is the portion of the Earth's surface where water is in a solid form, usually snow or ice. Seasonal snow cover, the largest component of the cryosphere, covers up to 33 percent of the Earth's total land surface. Glaciers and ice sheets cover about 10 percent of the Earth's land area. Nearly ... Full description.
