Google launched its third annual Google Science Fair today to find the next generation of scientists and engineers between the ages of 13 and 18.

Google explained on the official Google blog that students can enter the Science Fair in 13 languages, but deadline for submissions is April 30 at 11:59 p.m. PST. Google will select 90 regional finalists in June, and the public can meet the 15 finalists in a series of Google+ Hangouts on Air in August and even vote for the Inspired Idea Award. Judges will then choose 15 finalists, who will then go to Google headquarters for the last event on Sep. 23.

Lastly, at the finals, a panel of distinguished international judges will pick winners in each age group, along with one Grand Prize winner. The Science Fair is in partnership with CERN, the LEGO Group, National Geographic, and Scientific American, and Google said prizes include a $50,000 scholarship, a trip to the Galapagos with National Geographic Expeditions, as well as “experiences at CERN, Google or the LEGO Group and digital access to the Scientific American archives for the winner’s school for a year.”

Google will also give a $10,000 cash grant and offer a Google+ Hangout with CERN to the Grand Prize winner’s school. Meanwhile, the Scientific American will specifically give a $50,000 Science in Action prize to one project that “makes a practical difference by addressing a social, environmental or health issue.”

Google further plans to hold a series of Google+ Hangouts on Air on Mondays, Wednesdays and Fridays to showcase “exclusive behind-the-scenes tours of cutting-edge labs and science facilities, and provide access to judges and the Google Science Fair team.”
