The three most popular extracurricular activities at Deerfield Beach High School are definitely sports. As an I.B. student at Deerfield High, though, the most popular activities are MAO (Mu Alpha Theta - math club), Key Club, and Multicultural Club. I would definitely recommend Key Club, because as a member I can honestly say that all my experiences with Key Club have been absolutely awesome. Key Club is dedicated to helping its community, and through the club I have participated in numerous inspiring events, such as the Relay for Life, which raises money for the American Cancer Society. If someone likes science, I would also highly recommend the SECME club, because it's a very friendly atmosphere where a student can dabble in engineering (designing/constructing various projects) and robotics.
