   Google has kicked off Google Science Fair (GSF) 2014, its annual online competition for

bright, creative and ambitious teenagers who want to change the world with science. While the project is led by Google, it also has the backing of the Lego Group and world-famous publications National Geographic and Scientific American. The competition is open for students aged 13 to 18, who can sign-up now, form a team and begin working on a submission.

The winner will be rewarded with a ten-day exploration to the Galapagos Islands aboard the National Geographic Endeavor, as well as a VIP tour of ‘Spaceport America’ in New Mexico. Google is also throwing in a $50,000 scholarship and $10,000 for the winner’s school to purchase cutting-edge science lab equipment.

Google suggests that each project should be “an in-depth investigation of a science question or engineering problem” but otherwise, it’s up to students to pick and develop an idea that follows the competition rules.

Completed projects need to be submitted by May 12, 2014 at 11:59 PDT. Google will announce the regional competitors in June, ahead of global finalists in August and the competition winners in September.
