In this activity, students download NASA Hubble Space Telescope (HST) images of the Martian polar ice caps in summer and winter. Using image processing techniques, students measure and compare various images of the changing Martian and Earth polar ice caps. By completing this activity, they will understand that the sizes of the polar ice caps on Earth and Mars depend on the lengths of the seasons. ... Full description.

Students investigate the challenges of living and working in Antarctica and the technologies that help researchers meet those challenges. This six-day unit includes: teacher tools (downloadable readings, breakdowns of tasks, teacher strategies, grading sheet and rubric), an online activity (students review the preparation materials given to researchers traveling to Antarctica), classroom activities ...

The purpose of this lesson is to use NASA CERES instrument cloud data and a weather map to explore cloud coverage during a winter storm. Students will map locations using latitude and longitude coordinates as well as use a microset of satellite data to investigate cloud characteristics by applying percentage to determine cloud cover. When atmospheric scientists, including meteorologists, study weather ... Full description.

Conservation measures intended to increase the availability of water for fish and wildlife are outlined, and a link to the Dam and Reservoir Impact and Information Archive is provided. This archive is an extensive collection ... Full description.

This program provides an overview of the issues surrounding the construction of the Three Gorges Dam across the Yangtze River in China. When it is completed, this dam will produce the energy of 15 nuclear power plants and tame some of the river's deadliest floods. However, it is also the subject of much controversy. Topics include the loss of important archaeological, cultural, and paleontological ... Full description.

The purpose of this activity is to discover why an instrument shelter is built the way it is. Students construct shelters that have varying properties and place them in the same location or place similar shelters in different locations and compare temperature data taken in each shelter. Students should predict what will happen for each of the different shelter designs or placements and perform the ... Full description.

This is a lesson that enables the student to describe how hurricanes move and change appearance over time through the use of the pubic domain image processing software. Full description.

The purpose of this resource is to use a land cover type map to make environmentally sound decisions. Full description.

This website was developed for undergraduate students enrolled in an introductory earth or atmospheric science course. It is designed to supplement lecture and textbooks. Its goal is to make you a better consumer of weather information by providing dynamic graphics, animations, and science content about remote sensing, visible and infrared satellite imagery, and hurricanes. As part of the module, ... Full description.
