Google has just opened their third annual science fair for teenagers. This year the Google Science Fair will accept entries in thirteen different languages. Students are challenged to submit their ideas and projects that could change the world.

90 regional finalists will be chosen from entries all over the world. Fifteen of those regional finalists will be selected to go to Google’s headquarters to compete in the finals. Like last year, the grand prize includes a trip to the Galapagos. The winner’s school will also receive a prize that includes digital access to the Scientific American archives and a $10,000 cash grant from Google. Entries are due by April 30, 2013.
