DETROIT -

Ann Arbor elementary student Hannah Hu could soon have her art on the Google homepage for hundreds of millions to see.

Google has announced the 50 state winners in its seventh annual Doodle 4 Google competition, a contest open to K-12 students across the United States to redesign the Google logo inspired by the theme "If I could invent one thing to make the world a better place..."

Hannah Hu, a 5th grader from Ann Arbor's Logan Elementary School, is the state of Michigan winner with her doodle, "Ocean Cleaner", depicting an invention that would make our oceans a cleaner place for its inhabitants. Hannah's doodle was selected from over 100,000 received this year and the students' amazing ideas ranged from water purification to advanced robotics and nutrition solutions.

To help their favorites succeed, everyone across the USA can vote for their favorite doodle from the 50 state winners. Voting will be open until Friday, May 9, on this site: http://www.google.com/doodle4google/vote.html, and the public vote will determine the five national finalists (one in each grade group).

Google will announce these five national finalists and one of them as the national winner on May 21 at an awards ceremony at its headquarters in Mountain View, California, which all 50 state winners will be invited to attend.

The winning student will work with Google's team of professional doodlers to animate their doodle — for the first time ever!

The animated doodle will be displayed on the Google homepage on June 9. The winner will also take home a $30,000 college scholarship and his or her school will receive a $50,000 Google for Education grant towards the establishment and improvement of a computer lab or technology program.
