SAFER-SIM researchers attended the Girl Scout STEM Event at the University of Iowa. About 150 Girl Scouts from Eastern Iowa and Western Illinois participated. The event focused on a relevant, real-world, age-appropriate problem or “mystery” that would meet the following Girl Scout’s STEM impact goals—increasing girls’ interest in STEM, increasing girls’ confidence in their STEM-related abilities, educating girls about STEM careers, and exposing girls to STEM professionals. These Girl Scout Brownies earned a STEM Badge as a result of their experiences on this day. SAFER-SIM presented a driving science demonstration where the Girl Scouts collected and analyzed data on different driving surfaces. 35 Girl Scouts formed a hypothesis, graphed data, and discussed their findings.
