Brightstorm is a beta site which hosts a large number of Science and Maths videos. There are over 2500 videos on the site covering many different aspects of High School Science and maths.
From what I can see, the videos consist of teachers giving lecture-style presentations with occasional graphics. This makes them good for revision, although they may not be the most eye-catching or exciting videos. Each video comes with an accompanying transcript of the audio which is a useful feature. Firstly it makes the video more accessible plus a teacher could copy/paste the text into a worksheet and create a comprehension activity related to the video.
Videos are grouped by topic, plus US teachers/students can search for videos linked to the major textbooks.
Some of the content is free, and some needs to be paid for. The Maths and Science videos are free—these 2,500+ videos cover every topic in Algebra 1, Geometry, Algebra 2, Precalculus, Trigonometry, Calculus, Biology, Chemistry and Physics. The paid content includes additional tools such as a Maths Homework Checker and test preparation programs which include practice quizzes, downloadable materials and full-length practice exams.
