Visitors to the flashy Web site Froguts can dissect a frog without catching even a whiff of formaldehyde. Ten easy-to-follow explorations meld computer graphics and photos of real dissections to simulate the disassembly of an amphibian. Students wield virtual scalpels and scissors to slice open the frog's abdomen, bisect the heart to track blood flow through the three chambers, and expose the lobes of the animal's puny brain.

The lessons explore external anatomy and all of the major organ systems, and animations amplify the content, demonstrating processes such as the frog's four-step breathing mechanism. Although geared for high school students, the material might also be useful for introductory college courses. Richard Hill, a graduate student at the University of South Florida in Tampa, created the site to provide an anatomy lesson for schools that can't afford a dissection lab and to reduce the number of frogs slain for science.
