Welcome to the Web site for Ravenswood 6th-grade Earth Science. Your hosts: Richard Sedlock & Ellen Metzger, SJSU Geology and co-directors of BAESI. Send questions or problems to Richard at sedlock@geosun.sjsu.edu.
	Links to relevant sites/materials Discovering Plate Boundaries (masters of the figures, plus Teachers Guide and more). Subduction Zone animation — how California looked 100 million years ago. Pacific Ocean plate animation — plate boundaries in and adjacent to the Pacific Ocean from 80 million years ago to the present (Tanya Atwater animation). California's transform plate boundary — the change from subduction to transform motion since 38 million years ago (Tanya Atwater animation). Paper models of plate boundaries, fault types, volcanoes, and more — Hypercard stacks from the USGS pages for teachers. ABAG Shaking Maps — The "interactive" option sounds inviting, but the "static" maps option is much more stable and requires less bandwith. ABAG Liquefaction Maps — Likewise, "static" generally is a smoother experience than the "interactive" option. Phil Stoffer's guide to Rocks and Geology in the San Francisco Bay region (PDF file) NEW Jan 06: Minerals 4 Kids — Includes "Minerals in Your House," "Mineral Properties," and some games. NEW Jan 06: Minerals & Metals: A World to Discover — Minerals and metals at home. NEW Jan 06: Download this Word document: Rock Cycle Game.
		Presentations [will be updated as we go along] These are PDF files. Let me know if you prefer or need a different format. October 12, 2005: Plate boundaries, faults, earthquakes, etc. December 7, 2005: Earthquake hazards December 7, 2005: Volcanoes
		Links to other sources [Holding area; will be updated as we go along] This Dynamic Earth—an excellent on-line mini-text that covers the history and concepts of plate tectonic theory, published by the USGS (you can also order hard copies of the book for $7; see instructions at this same link). Topographic map of the Devil's Slide area (downloads a PDF file) Caltrans site for Devils Slide project — click around to find simulations of what the final project will look like. Recent California Earthquakes—USGS site. Recent World Earthquakes—NEIC site. Virtual Earthquake — Interactive site using synthetic seismic data; recently updated to a more inquiry-based form (IE on PCs only, though). IRIS fact sheets — One-page handouts in Spanish and English on topics such as locating earthquakes, why earthquakes happen, etc. The USGS Did You Feel It site, where you can report damage you felt in a recent earthquake, and view Mercalli intensity maps for recent earthquakes. The USGS ShakeMap site, which has intensity maps of recent earthquakes. Intensity maps for scenario earthquakes in northern California and southern California The Steinbrugge photograph library of earthquake damage, searchable by earthquake, structure type, and topic. Don Reed's Tsunami site — From our SJSU colleague's on-line course for Geology 105 (Introduction to Oceanography). Tsunami Fact Sheet — PDF file from the Earthquake Engineering Research Institute. Dec 04 Tsunami videos — Eight amateur videos; varying quality, but jaw-dropping impact. Also a link to before-and-after photos and general information about tsunamis. Volcano World — Excellent clearinghouse for volcano information, with Teachers' and Students' sections. How Volcanoes Work — SDSU site with lots of excellent background information (presented at college level). Mammoth Lakes/Long Valley area volcanism — Excellent USGS site includes lots of downloadable information and graphics. Lassen Volcanic National Park site — Includes a geologic history and stuff for kids. Geography, Geology, Hazards, and Natural History information — USGS Education site with maps, curricula, etc. Thanks to Phil Stoffer. San Francisco Bay — USGS site on the Bay/Delta region and its watershed. Tide and current charts — Plan your next trip to the coast...
