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 from the University of Oregon’s Physics Department provides a description of Olbers’ Paradox which asks why the night sky is dark. The site presents diagrams and an explanation for why a static infinite universe would have a brightly illuminated night sky. It also contains rationale for why this is not so, supporting calculations, and conclusions that can be drawn about the Universe.

This is a five-part interactive tutorial on the basics of energy in the context of introductory physics. The author presents Work and Energy as a means to analyze the motion of objects, an area of demonstrated weakness among secondary students. Detailed explanations and sample problems allow students to explore potential, kinetic, and mechanical energy, while also introducing related equations. Included are force diagrams, quick links to pertinent definitions, and links to animations that allow learners to visualize what is being discussed.

About Temperature is a tutorial that covers several topics about temperature, thermometers and thermodynamics. The text clearly explains topics such as the development of thermometers and temperature scales, heat and thermodynamics, kinetic theory, thermal radiation and the temperature of the universe. There are diagrams and helpful links. A version of the web page is available in Spanish as well. This website would be useful for students or teachers researching thermometers or introductory thermodynamics.

This diagram illustrates some of the most abundant stores of carbon and identifies some of the pathways in the carbon cycle along which carbon is transferred from one form to another. Long-term sinks of carbon are labelled in black; shorter-term fluxes are labelled in purple. Amounts are in billions of tons.
