This fall, Cornell’s graduate chapter of the Biomedical Engineering Society (BMES) hosted its semesterly outreach event, Girl Scout Engineering Day (GSED), an in-person program designed to get young girls in grades 2–8 excited about science and engineering and inspired to pursue education and careers in STEM.

Girl Scouts traveled to Cornell’s campus to take part in hands-on activities and experiments that introduced them to a range of scientific topics and engineering disciplines. Cornell graduate students led each station, giving the scouts the chance to ask questions, explore new ideas, and learn more about what it means to pursue a career in STEM.

This year’s program featured activities spanning multiple engineering fields, including biomedical, civil, and electrical engineering. Scouts built cell membranes, constructed earthquake-resistant towers, explored lipid polarity, made hydrogel beads, performed chromatography, and created crafts using thermochromic crystals. More than 130 Girl Scouts from across New York and Pennsylvania took part in the event.

Troop leaders praised the experience for its impact and engagement. “Our Brownie troop had a great time at Engineering Day and learned so much! We enjoyed all the activities and how much they kept the kids engaged, active and curious!” one leader shared.

GSED remains a cornerstone of BMES’s community outreach efforts, combining mentorship, hands-on learning, and a welcoming environment that encourages girls to see themselves as part of the future STEM workforce. As the program continues to expand, organizers hope it will inspire even more young learners to pursue their scientific interests with confidence and excitement.
