There are lots of places to find educational videos on the web. Mobento is one of those places. What makes Mobento different from most educational video hosts is that you can search for spoken words within a video. Mobento not only tells you which videos have specific words spoken in them, it will also show you a timeline of where in the video your specified words are spoken.

Applications for Education
Mobento’s collection of videos isn’t terribly large right now, but it has potential to be a great service for finding educational video clips that address the specific terms you’re searching for.
