Google has invited K-12 students nationwide to enter its Doodle 4 Google competition.

This year's theme is, "If I could invent one thing to make the world a better place..."

The goal is to help students think big.

The winner will receive his or her doodle displayed on Google.com in June; a $30,000 college scholarship; and a $50,000 technology grant for his or her school.

Students can submit doodles until March 20, and a winner from every state will be announced April 29. Last year's South Carolina winner was Noel Heil from Fort Mill Middle School.
