The UConn Explore Engineering (E2) Program is a two week residential STEM summer camp for current high school sophomores and juniors. During this week at the Storrs Campus, participants work in small groups with engineering faculty and students to learn what various engineers do in the workplace and see engineering concepts demonstrated. In the evenings, through our Grand Challenges, students focus on and fabricate a single engineering discipline-specific device. The program ends with demonstrations of items the students created during the week. Examples have included: rudimentary EKG devices, Smart Lego vehicles, fuel cell and other energy efficient devices, wooden bridges, and environmentally friendly processes.
