The Doodle for Google art contest is back for the fifth consecutive year. The theme of this year’s contest is, “If I could travel in time, I’d visit…”

The contest is open to K-12 students in the United States. The winner will receive a $30,000 scholarship and a $50,000 technology grant for his or her school. Submissions for the contest are due by March 23, 2012. This year pre-registration is not required. That should make it quicker and easier for schools to make submissions.
