In this activity, users examine satellite images from NASA's Total Ozone Mapping Spectrometer (TOMS) that show how much ozone is in the atmosphere over the Southern Hemisphere. They interpret the images to identify ozone thinning that develops over this region each summer, and compare its size from year to year. Using freely available image analysis software, ImageJ, users quantify the area of the ... Full description.

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 site focuses on the responses of Antarctica and its sea ice to climate changes. Two experiments help illustrate what happens as water warms and how this warming could affect sea levels and low-lying coastal areas. Links to more detailed information are also provided. Full description.

It features text, pictures, scientific illustrations, and links to satellite information and weather-related science activities. Full description.

This PDF document discusses a field activity for K-12 students. The purpose of the activity is to observe type and cover of clouds including contrails. Students will observe ten types of clouds and how many of three types of contrails are visible, how much of the sky is covered with clouds, and how much is covered by contrails. The PDF is an instructor guide with detailed advice for administering ... Full description.

This activity explores the potential for climate variability and change to trigger more frequent occurrences of El Nino, and the impacts that could result. Designed to teach through scientific inquiry, the activity seeks to stimulate thought about the long-term impacts of a warmer planet. Through their participation in this activity, students will access information at remote sites using telecommunications, ... Full description.

In this activity, students will assume the role of agronomists gathering and evaluating information about climate change and its possible effects on grasslands in western Nebraska and eastern Colorado. They will examine data related to temperature change, examine satellite imagery of Garden County Nebraska, and examine different varieties of grasses. They will then develop and present to the class ... Full description.
