ScienceHack – Science Videos Search Engine
http://www.ScienceHack.com/

ScienceHack is a unique video search engine for science videos. Every video is screened and approved based on accuracy and quality by their scientists. So far they have indexed: Physics, Chemistry, and Space; coming soon: Geology, Psychology, Robotics and Computer. Their database is relatively small, however, their scientists are working very hard to index every science video on the internet. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
