Science Olympiad is an American competition where elementary, middle, and high school student teams compete in various science-based events. It began in 1974 with 15 schools competing in biology, chemistry, and physics events. It has since expanded greatly with over 6,700 teams from 50 U.S. states competing annually at the regional, state, and national levels. The goal is to develop a positive scientific attitude among students and help recognize their talents in various scientific disciplines.
