This site was developed to assist students and educators with learning about the Great Lakes. The links provide materials on basic earth science concepts, a set of lesson plans on the lakes, and other Great Lakes topics. Concepts covered include Langmuir circulation, longshore current and beach drift, sediments, stream flow, seasonal stratification and water quality. Full description.

In this lesson, students research maps, weapons and weather from a variety of wars, then create a presentation showing the impact weather and topography has had on military operations. Full description.

The Atmospheric Radiation Measurement (ARM) Program is an important part of the U.S. Department of Energy's (DOE's) strategy to understand global climate change. The ARM Program has established three outdoor research sites around the world. Scientists gather and use the data from these sites to study the effects of sunlight, radiant energy, and clouds on temperatures, weather, and climate. This site ... Full description.

The National Climatic Data Center (NCDC) is the world's largest active archive of weather data. Climate data for cities and locations throughout the U.S. and around the world are available here. Products include land-based, upper air, satellite, and marine measurements of precipitation, wind, atmospheric pressure, clouds, and solar activity. Educators and government researchers can access many of ... Full description.

This site presents average ice conditions estimated using satellite passive microwave data for the most recent month available, as well as snapshots of trends and anomalies that compare these recent conditions with the mean for the month. Full description.

This lesson plan allows students to participate in a number of in-class experiments using ice. Students will come to understand the effects of global warming on icecaps and the worldwide consequences that may result. Full description.

BASIN is a local community service network offering public access to environmental information. BASIN's initial focus is on water in Boulder County, CO: where it comes from, goes to and how it is used. Watershed, recreation, precipitation, personal action, and community uses are major focuses in this site. Full description.
