Everybody is invited to submit educational videos to WatchKnow, an educational online platform due to be launched September 20 (preview here) which strives to collect videos, lectures and animations suitable for kindergartens, primary and secondary education, much like WAYS partner wlp, the world lecture project does it for university-level education. Materials correctly submitted to WatchKnow until September 26 will be eligible for a prize draw.

It does not matter whether you created the video yourself or just found it on the web, but you should be able to provide the data relevant for copyright, and give an explanation why that video is particularly suited for educating children or teenagers. Watchknow is headed by Larry Sanger who also founded Citizendium, an educational Wikipedia offspring directed at university students, researchers and adult education.
