Here's two video contests for schools and students.

Quantum Shift TV has launched a video contest with social impact for students in the U.S. and Canada grades one through twelve: Be the Change! Share the Story! School Video Contest.

Student teams will work on social or environmental projects of their choice and document their progress in a series of two short videos.  The winning schools will receive a prize package worth $50,000.    The contest rules, prizes, and eligibility requirements are spelled out here.  (Hat tip Britt Bravo's Have Fun, Do Good Blog)

Interwrite Learning and Teacher Tube are sponsoring a contest.  Participants of the contest will create a short music video parodying the song of their choice. The video should demonstrate how different kinds of technology are being used in the classroom.  The winning videos will receive prizes valued at approximately $15,000.  The rules, eligibility, and more information can be found here.
