More Cool Stuff Teachers, check out the Plate Tectonics teacher's guide. There are several sites on the Web from NASA's Learning Technologies Project (LTP) that offer information about volcanoes and plate tectonics. VolcanoWorld is an excellent reference for learning and teaching about volcanoes and volcanology. The site provides an excellent student and teacher guide concerning plate tectonics and volcano information. http://volcano.und.nodak.edu/vwdocs/vwlessons/atg.html Exploring the Environment (ETE) features interdisciplinary modules that use satellite imagery as a tool, problem-based learning as methodology, and the World Wide Web as a means of delivery. http://www.cotf.edu/ete/modules/volcanoes/volcano.html Athena offers curriculum and resource materials using geophysical and other data sets acquired over the Internet. http://www.athena.ivv.nasa.gov/curric/land/index.html Virtually Hawaii is a Web site that offers, via the Internet, virtual tours of Kauai, Oahu, Molokai, Maui, and the Big Island (including a virtual field trip of the Kilauea volcano). http://hawaii.ivv.nasa.gov/space/hawaii/vfts/kilauea/kilauea.vfts.html For more information on earthquakes and volcanoes, check out the following sites. For information on "hot spots," plates, seafloor spreading, and the "Ring of Fire," check out the USGS/Cascades Volcano Observatory in Vancouver, Washington. http://vulcan.wr.usgs.gov/Glossary/PlateTectonics/ For earthquake information, check out the US Geological Survey's National Earthquake Information Center. http://wwwneic.cr.usgs.gov/neis/general/handouts/rift_man.html To learn more about radio astronomy and how it is used to study the Earth, check out the two sites below.
