Doodle for Google is an annual contest for students K-12, the winners' doodles get featured on the US Google's homepage and money towards college scholarships. Back in January Google opened submissions, and accepted until March. This 2021's theme is, "I am strong because...". Today Google revealed the 54 state and territory winners. Submissions are organized by 5 grade groups: K-3, 4-5, 6-7, 8-9, 10-12. Decisions were made by a state-by-state basis, with 10 or more winners per state or territory. Users now have the opportunity to vote for a national finalist in each group.
