Google said today it is holding its fourth annual Doodle 4 Google contest, which is open to K-12 students in the U.S. for a chance to design the company’s homepage.

 Participants in this years Doodle 4 Google contest will have a chance to win a $15,000 scholarship and a $25,000 technology grant for their school.

The theme for this years contest is “What I’d like to do someday…” the Google Blog offers more details. “While most of this year’s contest remains the same, we’ve made some exciting changes based on your feedback. Now, parents or guardians can register their students directly, and if a school registers, there’s no limit on the number of doodles they can submit.”

“But remember, we only allow one entry per student. We’re also pleased to partner with Boys & Girls Clubs of America and Girl Scouts of the USA, two organizations that truly bring this year’s theme to life.”

“Once you’ve registered your students and they submit their artwork, Google employees and our panel of guest judges, including Whoopi Goldberg, gold medal ice skater Evan Lysacek and “Garfield” creator Jim Davis, will narrow down the submissions.”

The top 40 regional finalists will get a trip to New York City and a visit from Google in their hometown. Their doodles will be displayed in an exhibition at the Whitney Museum of American Art.

Parents and teachers can register students by March 2 and all entries need to be postmarked by March 16.
