Teacher tube (http://www.teachertube.com/viewVideo.php?video_id=112614) and School tube (http://www.schooltube.com/video/8b5334c8aac84146b756/DNA%20and%20RNA%20-%20Part%201) offer videos of Varying quality over a wide variety of topics. I thought that the videos were decent regarding quality and information presented, but were not as good as the united streaming that we use at Marysville High School. There are better filters for quality on the Discovery website. Although there are a large number of video clips on Teacher tube and School tube, I spent a great deal of time searching for a clip that had solid content versus being creative or entertaining. I would recommend Discovery United Streaming for my fellow science teachers.
