An interactive slide show explores the journey of a single snowflake onto and through a glacier. This journey, which can take as much as 30,000 years to complete, shows that the life cycle of a glacier can be more complex than originally perceived. Full description.

In the Clouds Photography specializes in photos of weather skyscapes taken by a photographer who is also an atmospheric scientist. Spectacular images of tornadoes, lightning, supercells, and other related severe weather are available, as are weather photos of a less severe nature;strange cloud forms and optical phenomenon such as rainbows, halos, and glories. Weather-related photos are a specialty ... Full description.

This lab activity investigates porosity, permeability and relationship. Students will understand porosity and how gases/liquids can move through permeable materials (permeability). Also, students will repeat a valuable scientific experiment performed on the International Trans-Antarctic Scientific expedition by expedition members and Dr. Mary Albert (of the USA Cold Regions Research and Engineering ...

Arctic Science Journeys Radio (ASJ) is a free service that offers interesting stories about science, culture, and the environment of the far north. This audio file of a radio story describes the research of one scientist into the animals and plants that live within the ice of the Arctic Ocean. Full description.

The Antarctic Meteorological Research Center provides recent and archived imagery of icebergs, including movies. Icebergs from the Ross, Ronne, and Larsen ice shelves are pictured. Links to a webcam, a Frequently Asked Questions page, and other sites providing pictures and information about icebergs are also provided. Full description.

This information about the Lunar Prospector mission to the Moon discusses the possibility that ice exists on the lunar surface. The article indicates that no native water ice has been found on the moon. If ice has been found, it most likely originated from meteors and meteorites which periodically bombard the lunar surface. Full description.

The purpose of this lesson is for students to explore the nature and composition of a comet. The student will select ingredients to create a comet and will learn to identify ingredients responsible for a comet nucleus, and how changes in the nucleus when the comet approaches the Sun cause two different kinds of tails to form. Students can explore some facts, myths, and legends linked to the appearance ... Full description.

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.
