NASA’s sites are great resources for the classroom, and many are targeted for younger students. But my favorite one is the Astronomy Picture of the Day, http://apod.nasa.gov/apod/archivepix.html. For the truly curious among us, the APOD archive offers a chance to browse previous daily posts, finding topics of which we may not have even been aware. Each photo image has links to more information about the subject, and many APOD posts are videos like the one shared by Brad Fountain, All Alone at Night, on the DEN blog, March 5th. APOD has a hot list of educational links to enhance the curiosity factor, http://apod.nasa.gov/apod/lib/edlinks.html. Add the APOD site as an RSS feed to your blogs and webpages to create an instant resource for the curious students in your class. Our Universe is a truly amazing place!
