Google is asking Canadian students to submit a design for the banner atop the search engine home page to celebrate Canada's 150th birthday.
Students from kindergarten to Grade 12 have until May 2 to submit a Google doodle based on the theme "What I see for Canada's future is"
The winning student's doodle – to be judged on "artistic merit, creativity and originality" – will be displayed on the Google.ca homepage for a day.
The winning "doodler" will receive a $10,000 scholarship, a $10,000 technology grant for his or her school and a paid trip to Toronto where the top doodle will be revealed on June 13.
Google says students can submit a doodle made from almost any medium, including computer code.
The winning doodle will be selected by Google employees and a panel of guest judges which includes federal Science Minister Kirsty Duncan.
Students, parents and teachers can download entry forms and contest rules at g.co/d4gcanada.
