The annual Science Olympics at Marion Street School gave fourth-graders a fun and fast-paced way to show off their science knowledge. The competition began in the four fourth-grade classrooms, where students faced off to qualify to represent their class at the Olympics. With their classmates there to cheer them on, the four teams prepared to do battle, answering questions that tested their understanding of biology, chemistry, physics and earth science. After several rounds of play, all four teams had racked up impressive scores. The Castellano Chemists and Marvelous Marrs, who were tied for first place, went head-to-head in a heated tiebreaker. The two teams proved to be so evenly matched that it took six playoff rounds before Mr. Marr’s team finally claimed victory.
