How do you play piano with bananas keys? How do you detect seismic activity? How do birds use their beaks to pick up food?

More than 200 young stu­dents and their fam­i­lies explored the answers to these ques­tions ear­lier this month at STEM Sunday, a sci­ence and engi­neering event held in Northeastern’s Cabot Phys­ical Edu­ca­tion Center. Vol­un­teers from the uni­ver­sity com­mu­nity ran hands-​​on activ­i­ties at the “reverse sci­ence fair,” which was orga­nized by Northeastern’s Center for STEM Edu­ca­tion, led by Claire Duggan. The event was part of the National Sci­ence Foundation’s annual Engi­neering Research and Inno­va­tion Con­fer­ence, which was hosted by the Col­lege of Engi­neering.

David Truong, who just com­pleted the fifth grade at Rus­sell Ele­men­tary School in Boston, one of Northeastern’s partner schools in Mayor Thomas M. Menino’s Step UP pro­gram, loved the event. “There were a lot of fun things there, like the robot we moved with a con­troller, and making paper towers and gliders,” he said. “There was also a wizard who talked about saving electricity.”

Truong was one of four dozen middle school stu­dents who attended the event as part of their first day of the Exxon­Mobil Bernard Harris Summer Sci­ence Camp. The free, two-​​week pro­gram — run by the Center for STEM Edu­ca­tion and named after the first African-​​American to con­duct a space­walk — gives stu­dents the chance to work along­side North­eastern fac­ulty, staff and stu­dents on projects aimed at increasing their knowl­edge and expe­ri­ence in the areas of sci­ence, tech­nology, engi­neering and mathematics.

Vol­un­teers from orga­ni­za­tions including the Cam­bridge Sci­ence Fes­tival, Maker Faire, NStar, and the Cape Cod National His­tory Museum, and grad­uate and under­grad­uate stu­dents from col­leges across the country par­tic­i­pated in the conference-​​led activities.

David Schmidt, a North­eastern bio­engi­neering grad­uate stu­dent, helped the young engineers-​​in-​​training build the tallest tower they could using only two sheets of news­paper. “Paper towers are a nice cost-​​effective activity because you can bring them into any class­room and use them for any age group,” he said. “Our tallest tower was actu­ally built by a mom, so clearly building them never gets old.”

Schmidt is also a member of Northeastern’s robotics team, the NUTRONS, which demoed a robot at the event. “These activ­i­ties are a sneaky way to teach chil­dren about engi­neering,” Schmidt said. “They don’t know they’re learning.”
