Plate Tectonics Jigsaw The Task The task of the group as a whole is to outline what is meant by the "Theory of Plate Tectonics", outline the development of the theory and provide evidence to support or reject the theory. The task of each individual in the group is to supply the evidence that would be provided by a particular geologist or scientist. A "job description" for the assumed profession should also be included The Process and Resources Sites for everyone: glossaries, background and general information Volcano and Hydrologic Hazards, Features, and Terminology - from United States Geological Survey http://vulcan.wr.usgs.gov/Glossary/ This Dynamic Earth: the Story of Plate Tectonics - from United States Geological Survey http://pubs.usgs.gov/gip/dynamic/dynamic.html Evidence in support of the Theory of Plate Tectonics: - from Georgia Perimeter College http://facstaff.gpc.edu/~pgore/geology/geo101/plateb.htm Paleomap Project - animations and other graphics http://www.scotese.com/ An Introduction to Plate Tectonics - from Volcano World http://volcano.oregonstate.edu/education/vwlessons/lessons/lesson1.html Geol 456/656 - The Mechanism of Plate Tectonics - from Nevada Seismological Laboratory http://www.seismo.unr.edu/ftp/pub/louie/class/plate/mechanisms.html Earth Like A Puzzle - from Scripps Institution of Oceanography http://scripps.ucsd.edu/voyager/earth_puzzle/recycling_plates.html Plate Tectonics - from University of Alabama http://www.geo.ua.edu/intro03/Plate.html Evidence Supporting Continental Drift - from For Kids Only Earth Science Enterprise, NASA http://kids.earth.nasa.gov/archive/pangaea/evidence.html Plate Tectonics - from St Vincents College http://www.stvincent.ac.uk/Resources/EarthSci/Tectonics/ Scientific historian Use the Internet information linked below to compile a timeline of events and people who have helped formulate the theories of Continental Drift and Plate Tectonics such as: Alfred Wegener; Arthur Holmes; Harry Hess; Edward Seuss; J.

Now group members come back to the larger WebQuest team with evidence gained by searching from the perspective of your chosen scientist. You must all now collaborate to justify whether you accept or reject the Theory of Plate Tectonics. Each of you will bring a certain viewpoint to the answer: some of you will agree and others disagree. Use information, pictures, movies, facts, opinions, etc. from the web pages you explored to convince your team mates that your viewpoint is important and the evidence relevant and should be part of your team's answer to the Task. Your WebQuest team should write out an answer that everyone on the team can live with. Conclusion You and your team mates have learned a lot by dividing up to address different issues and points of view. Now's the time to put your learning into a format that can be shared with other interested people. As a group, prepare evidence to support or reject the theory of Plate Tectonics. What do most geologists consider to be the cause of Plate Tectonics? Will the continents come together again some time in the future? Has there only been one episode of plate movement? Your group may decide to present their evidence and arguments in written format, as a brochure or as a poster, in electronic format, as a presentation or web site, or through an oral presentation or debate. Each member of the group should also provide: a job description for their assumed role; and a list of new words (with explanations) that were necessary to understand this topic
