Contest winners also gain exposure on one of the world's most heavily trafficked websites. The winning doodle is up only for 24 hours, but the home page generates millions of views per day.

What's this year's theme?

"There are a million and one facts, interests, and quirks that make everyone unique," Google said. "For centuries, artists have created paintings, sculptures, self-portraits, and more to offer insights into their personalities and values. Now, we're asking kids to do the same by creating a doodle that shows the world what they're passionate about, what gets them excited, or what they dream about. In other words, we're asking that this year's doodles explain 'What makes me...me.'"


Guest judges and Google's Doodle team will pick the best doodle from each of the 50 states as well as one from Washington DC, Puerto Rico and Guam. From February 8 to 22, 2016, the U.S. public votes for their favorite doodle among the 53 finalists. On March 28, a panel of Google employees chooses one finalist from each of the five grade groups and then names the national winner.

Past winners have included an imaginary device that cleans drinking water and a reunion between a girl and her father returning home from war.
