The National Park Service has developed this exemplary set of educational resources which draws on their greatest assets, namely national parks from Maine to Utah. The materials are specifically designed for teaching geology, but it's easy to see how these items could be incorporated into general science classes. The main area on their homepage features over a dozen teacher guides and park programs that feature detailed geology lessons that draw on the landscapes of Yosemite National Park and the dynamic volcanoes of Hawaii. On the right side of the page, visitors can scan through the "Highlights" area to learn more about online park images, park maps, and even peruse a calendar of upcoming educator workshops. The site is rounded out by the "Geology Books and Media" area, which features information about technical reports, textbooks, and geology-themed children's books.
