Brightstorm = Free Math & Science Videos

Brightstorm is a web site I learned about from Technology Tidbits: Thoughts of  Cyber Hero. Brightstorm offers free Science and Math how-to videos on a wide variety of high school and middle school topics.

Here's a feature that sets it apart from the rest, though: In addition to arranging the videos by topics like Biology, Chemistry, Physics, Algebra, Geometry, Calculus, and so on, Brightstorm has also taken a handful of popular textbooks from various publishers and allows users to sort through videos that are cross-referenced by chapter and lesson within each title. Handy!
