Scientific American's Ask The Experts Web site (last mentioned in the October 15, 1997 Scout Report for Science & Engineering) is worth mentioning again as a great resource for mid and upper-level science classes. Divided into categories like Astronomy, Biology, Environment, and Medicine, students can submit their own questions or read answers to questions posed by other inquisitive minds. Some of the more recent questions include "If T. rex fell, how did it get up, given its tiny arms and low center of gravity", "How do seedless fruit arise and how are they propagated?", and "How do you get laryngitis?" The site is continually adding answers to a variety of interesting questions.
