Science Olympiad is an engaging academic competition for students in grades 6-12, where teams from schools across the country (and internationally in some cases) compete in a variety of science, technology, engineering, and mathematics (STEM) events. Participants tackle hands-on challenges, such as building and testing structures, conducting experiments in fields like chemistry or physics, and solving problems in areas like anatomy or environmental science. The event fosters critical thinking, teamwork, and a passion for STEM, with students preparing through research, practice, and collaboration. Held annually, it culminates in regional, state, and national tournaments, where top teams earn recognition and awards for their innovative solutions and knowledge. This program not only highlights real-world applications of science but also inspires future leaders in STEM fields.
