Title: Mass Extinction
Url: http://www.pbs.org/wgbh/nova/sciencenow/3318/01.html
Publisher: Public Broadcasting Service (U.S.)
Description: This set of multimedia resources, produced for the NOVA television broadcast 'Mass Extinction', explains mass extinctions in general, and in particular the extinction event that occurred at the end of the Permian period, in which more than 90 percent of all marine species died out. An interactive feature presents some of the theories about what caused this event, and lets users vote for the one they consider most likely. There is also a video clip from the broadcast, an audio clip of an interview with a researcher who is using high-precision dating techniques to understand the time scale of the Permian extinction, and an ask-the expert feature in which a scientist from the Smithsonian Institution answers questions about the Permian and other mass extinctions. Other links access a teacher's guide, additional reading materials, and a transcript of the broadcast.
