AIRNow is a cross-agency U.S. government web site that provides information and forecasts of air quality across the country. The organization's home page features news articles, information on the Air Quality Index (AQI), and highlighted forecasts for areas with AQIs of special concern. An interactive map shows weather systems, winds, and areas where air quality is likely to be compromised by ozone, particulates, ultraviolet radiation, or other pollutants, with links to current conditions, forecasts, and webcams for selected cities. There are also links to educational materials on air quality for younger students, interactive features and visual materials for older students, and curriculum materials for teachers. Other resources include information on AQI for health providers, older adults, and TV weathercasters; information on air quality and personal health, smoke from fires, and links to air quality information from other countries.

ARKive is a collection of photographs, videos, and fact-files illustrating thousands of species of animals, with emphasis on the International Union for Conservation of Nature and Natural Resources (IUCN) Red List of endangered species, and on species found in Britain. For each animal there are approximately 10 minutes of video footage, 6-10 still photos, and sound recordings (where appropriate), creating a complete profile of the species' characteristic behavior and appearance. The images are accompanied by a page of facts, including taxonomy, a physical description, conservation status, geographic range, habitat, and other information. There are also links to other animals with related taxonomic families, habitats, or conservation status.

Animals are faced with a constantly changing environment which they must adapt to. This lesson looks at gray whales and the specific adaptations these animals have made in order to develop crucial abilities such as keeping warm in icy water, seeing underwater and knowing when it's time to migrate. Students can click on four different areas: the whale's body, head, flippers and tail, and learn how each body part helps gray whales to thrive in their environment.

This collection of aerial photographs is intended to show changes over time in the landscape of Colorado; for instance, the appearance of a reservoir in a mountain valley, changes in vegetation or ground cover, or the growth of towns and cities. The online collection, consisting of over 1700 digitized photos, was taken by the U.S. Forest Service from 1938 to 1947 and covers Boulder, Clear Creek, Eagle, Gilpin, Grand, Jefferson, Larimer, and Summit Counties. The photographs can be searched or browsed using a map search or a geographic keyword search. Searches will bring up information and metadata (longitude and latitude, landmark, county, topographic quadrangle, scale, and others) about each photograph and a 150 dpi image that can be downloaded free of charge.

The Indian Ocean tsunami of Dec. 26, 2004, ranks as one of the great disasters of human history. The key to learning from any disaster‰ŰÓwhether tsunami, earthquake, storm, fire or volcano‰ŰÓis to gather as much data as possible, as quickly as possible. NSF‰ŰŞs Learning from Earthquakes (LFE) rapid-response program quickly dispatched dozens of researchers to the devastated regions. This web site contains reports of the research efforts in Indonesia, India, Maldives,and Sri Lanka including video interviews with the researchers and day to day accounts.
