Course 1 seniors presented work from the capstone class at the Cambridge Science Festival’s Science Carnival held Saturday, April 19 at the Cambridge Public Library. Zach Balgobin, Sydney Beasley, Derek Chang and Paula Gonzalez showed their projects to more than 150 visitors, including children ranging in age from 0.5 to 13 years and their parents. The CEE students demonstrated the air quality sensor nodes they designed, built and deployed across campus, and displayed models of structural towers they built and tested to failure earlier this semester. According to CEE research scientist and capstone (1.S992, 1.013) instructor Eben Cross, feedback from visitors was along the lines of, “Wow, you built that?” and “That’s awesome!”
