It's time to sharpen your kids' pencils for the Doodle 4 Google competition. You've probably noticed Google gives its logo (a.k.a. Google Doodle) makeovers to celebrate special holidays, birthdays and events. Usually, a man named Dennis Hwang draws these Google Doodles (you can see him work his magic in the video below), but Google is giving US students in grades K-12 the opportunity to design a doodle for the Google homepage. The rules are:

Students will be asked to draw a doodle that best represents the theme "What if...?" We ask ourselves this question every day when we build our products, so we thought we would ask the same of the future doodlers.
A panel of expert judges and Googlers will select 40 regional winners, who will be invited to the Googleplex in Mountain View, California, in May. Four national finalists will be announced as the result of a public vote. From there, Dennis will select one lucky student whose doodle will be on the Google homepage for a day in the U.S. This winner will also receive a $10,000 college scholarship and a technology grant for his or her school.

The information for schools and families is available on this page. To see a fun video of the google logo creation, read more
