Before your students get carried away with the latest incredible tale, urban legend or Internet rumor, check out the Museum of Hoaxes at www.museumofhoaxes.com to make sure that what they're hearing is on the level.

This Web site not only includes a compendium of hoaxes throughout history but also lists them by category (ghosts, political, religious, etc.). Also covered are the Sept. 11 hoaxes, including a purported photo of a tourist at the top of the World Trade Center just seconds before it was attacked, or the alleged prediction by 16th-century astrologer Nostradamus of the terrorist strikes. Although completely untrue, both stories were circulated widely, even by some reputable news organizations.

The site also features hoax pictures, hoax Web sites, a "gullibility test," a "hoax mailbag" and a free e-mail newsletter.
