Google's Young Scientists Are Out To Change The World

Since 2011, Google has been challenging innovative teens aged 13-18 from all around the world, to use their technology and scientific know-how to transform the world into a better place. Contestants are categorized into three age categories (13-14, 15-16, 17-18) and five semi-finalists are selected from each. The fifteen youngsters are then flown to the company's headquarters in Mountain View, CA, to present their ideas to a group of judges, who select a winner from each category, one of whom is also declared the overall winner.
