We have annotated several hundred teaching resources cataloged in the National Science Digital Library with spatial concept terms listed below. We have also created a new TeachSpatial collection annotated in the same way. The concept terms were drawn from the U.S.National Science Education Standards (NSES 1996) for topic areas B - Physical Science, C - Life Science, D - Earth and Space Science, as well as from the 1994 U.S. Geography Teaching Standards for grades 9-12. Those standards can be browsed here.

This site contains a mineral database with access to 4,339 individual mineral species descriptions with links and a comprehensive image library. Mineral data on individual species are linked to a mineral table by crystallography, X-Ray powder diffraction, chemical composition, physical and optical properties, Danas new classification, Strunz classification, mineral specimen images, and alphabetical listings of mineral species. There are extensive links to other sources of mineral data and information. Visit the Whats New section for details.

This United States Geological Survey (USGS) website explains volcanic gases and their effects on the Earth and its life. The report discusses gases trapped in magma below the Earth's surface as the driving force of volcanic eruptions. Types of gases, such as sulfur dioxide and carbon dioxide, and their potential effects are described. A comparison of volcanic gas composition in three different volcano types is also given.
