Cabrini High School’s geometry students took their learning to new heights—quite literally—by successfully receiving satellite signals and communicating with amateur radio operators using mathematical principles. This innovative, hands-on activity combined STEM education with real-world applications and showcased the cutting-edge potential of geometry in technology and space exploration.
Using their knowledge of similar polygons, scale factors, and proportionality, students measured and analyzed amateur radio antennas, including cubical quads and Yagi antennas. These antennas rely on precise mathematical relationships between their reflector, driven, and director elements, an ideal demonstration of similar polygons and their use in engineering and communications.
Students successfully received signals from satellites, including one traveling as far away as Maine. The experience was further enriched as geometry teacher Alvin Mahler used a cubical quad antenna and radio to enable students to ask questions of amateur radio operator Michael Decossas, Jr., a student at Archbishop Shaw High School, through a local repeater.
This dynamic, hands-on STEM experience highlights Cabrini High School’s dedication to preparing students for the future by integrating cutting-edge technology with fundamental math concepts. By bridging the gap between textbook learning and practical application, this activity reinforces how math and science fuel innovation in today’s world. Cabrini High School is quickly gaining recognition as a school for young women who want to invest in a future in science, mathematics, engineering, and technology. Through partnerships with industry leaders, state-of-the-art lab activities, and creative faculty, Cabrini is shaping the next generation of female innovators and problem-solvers.
