This Web Seminar, developed in collaboration with the National Science Digital Library (NSDL) took place on Thursday, September 25, 2008, from 6:30 p.m. to 8:00 p.m. Eastern time. In this program Dr. Cathy Ezrailson, Assistant Professor at the University of South Dakota and Dr. Susana Deustua, Researcher at the Space Telescope Science Institute, and co-chair of the US International Year of Astronomy, provided content and resources related to astronomy from The Physics Front, a digital collection of resources for teaching physics for secondary teachers that is a part of ComPADRE, the NSDL digital library for physics and astronomy.

I highly recommend this web seminar for anyone needing to brush up on their basic astronomy.  Dr. Susan Deustua and Dr. Cathy Ezrailson do a fabulous job explaining how astronomers classify stars.  They also relate how emission and absorption spectra are used to determine what elements make up individual stars. When my high school chemistry class was studying emission and absorption spectra, I used the information in this web seminar as an example of a real world application of the uses of the data collected using the electromagnetic spectrum.  Included in this web seminar are some wonderful interactive models. The icing on the cake were the explanations of the evolution of stars, planetesimals, and planets like Jupiter. A wealth of online resources are given for teachers like me who want to find out more!

This webseminar starts at a low level but moves through high school and into some college level information by the end of the presentation so it has something for a variety of levels of instruction. It also contains links to additional website resources and at the end one of the presenters shows websites with lesson ideas, data for students to use for projects at It was sometimes hard to follow what the presenters were saying but they did present information that went from basics to much more complicated ideas on astronomy and I was excited by the idea that there was data that students could use in lessons.
