What do wearable sensors, natural nitrogen depletion, aromatic alarm clocks, and diazotroph bacteria have in common? Maybe not so much at first glance, but they're all inspirations behind a few of the 15 finalist projects in this year's Google Science Fair. And now it's your chance to cast your vote for the Voter’s Choice Award.

Through September 14, you can select which of the 15 Global Finalists has the greatest potential to change the world. These projects were selected from amongst thousands of entries earlier this year and represent nine countries from across the globe. These bright budding scientists have all turned their passion for science and engineering into a project that can change the world for the better, and have found inspiration from their world around them: whether it’s using technology to help care for a relative, using chemistry to improve the environment, or developing a method to help prevent cyberbullying. Oh and did we mention that all of them are 17 or younger?

The winner of the Voter’s Choice Award will receive a $10,000 grant from Google to help develop their project. We will announce the winner at the Google Science Fair awards ceremony in Mountain View, CA on September 22nd, where we will also announce our age category and grand prize winners.

Head to googlesciencefair.com before September 14 to support these young scientists with your vote and let us know which project you think will change the world.
