As of Fall 2001, all the following web sites are active. However, they are subject to change and may not all be available when students begin their work with the SAM II activities.

If too many of these sites are no longer active, the developers and creators of SAM and SAM II recommend using the World Wide Web search engine "Google."

http://www.google.com/

Enter "Google" using key words from each SAM II activity. The following table gives a sample of key words to use in entering the "Google" search engine.

Activity 1	Clouds, Environmental Technology Laboratory, NOAA
Activity 2	GPS, Hurricane Georges, Forecast Systems Laboratory, National Hurricane Center, NOAA
Activity 3	Ozone, Ozone Hole, NASA, Aeronomy Laboratory, NOAA
Activity 4	Tornados, Skew-T, National Severe Storms Laboratory, NOAA
Activity 5	El Niño, La Niña, Pacific Marine Environmental Laboratory, NOAA
Activity 6	Greenhouse Effect, Global Warming, Climate Monitoring and Diagnostics Laboratory, NOAA
