This great educational site from Cal Tech offers all sorts of great resources to assist in learning about the universe. Using the fun gear-like menu on the left of the screen, visitors can pick from site areas such as the Cosmic Classroom (which offers classroom activities, lessons, reference info., and an Ask an Astronomer option), Cosmic Kids (where kids can learn about what's in space through stories and resources like the Infrared Zoo), the Video and Image Galleries, and lots more. The site should be a great resource for teachers introducing students to the study of the universe or those visitors who are simply interested in getting lost in space for a while. This site is also reviewed in the July 9, 2004 _NSDL Physical Sciences Report_.
