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.

Spectra is a very informative website about how astronomers use spectra to understand what stars are made of, their structures, and their evolution. The page begins with an introduction to the electromagnetic spectrum and then goes into great detail about the properties of light. Then it talks about how matter both creates and destroys radiation. Then it discusses how to interpret absorption and emission lines. The website ends with how astronomers use spectra to understand stars, galaxies, other objects in the universe.

This web page provides information and a graphical exercise for students regarding the interaction between magnetic field lines and a plasma. The activity involves tracing a typical interplanetary magnetic field line, dragged out of a location on the Sun by the radial flow of the solar wind. This illustrates the way magnetic field lines are "frozen to the plasma" and the wrapping of field lines due to the rotation of the sun. This is part of the work "The Exploration of the Earth's Magnetosphere". A Spanish translation is available.

This resource is a student tutorial on magnetism designed for beginning physical science students. It is organized into sequenced headings that each contain interactive simulations and reflective questions. The first half of the tutorial gives students a conceptual framework to understand properties of magnets and magnetic behavior. The topics then broaden to include magnetic lines of force, magnetic field, electromagnets, electric motors, and galvanometers. This resource is part of a collection developed by the Non-Destructive Testing Resource Center at Iowa State University.

Tutorial

This activity will help younger students to determine the behavior of sunlight from observations made outside and inside the classroom. They will learn about how light travels by using mirrors, prisms, flashlights, and various objects to create shadows. Concepts include the fact that light travels in a straight line and that shadows are oriented directly away from a light source.

This lesson serves as an introduction to color and to both line spectra and continuous spectra, with applications to sunlight. It also explains how a glass prism resolves light into its rainbow components and the difference between spectral colors and the colors perceived by the eye. Students will learn that hot solids (or dense gases) radiate a continuous spectrum, related to their temperature. But the colors of a glowing rarefied gas are characteristic of the atoms emitting them.

It is said that a picture is worth a thousand words. If so, then an informational graphic is worth a thousand data entries if not more. Be they histograms, trend lines, scatterplots, pie charts, or choropleth maps, informational graphics allow us to discern what would otherwise be unmanageable loads of data indecipherable to the average person. Tufte had two major agendas with The Visual Display of Quantitative Information. One was to identify many of the mistakes and abuses common to informational graphics and to finger the main culprits.
