From Khan Academy: “We’re proud to support the Breakthrough Junior Challenge video contest again this year. To qualify, create a short (under three minutes) video explaining a challenging concept in physics, mathematics, or the life sciences in an engaging, illuminating, and creative way. If you win, you’ll receive the college scholarship, your teacher will receive a $50,000 prize, and your school will get a new $100,000 science lab!”
