University of Virginia engineering students gave up a big chunk of a recent Sunday to teach pre-teens lessons on topics ranging from electric circuits to machine learning through the University Students Taught Engineering Program.
The Society of Women Engineers at UVA sponsored the event for about 80 middle schoolers from across the region. Gathered in the basement of Olsson Hall, about 40 volunteers divided the students into four color-coded groups – pink, blue, purple and green – and led three different classes for each group during a four-hour workshop, with a break for a pizza lunch.
Class lessons included “How circuits really work,” “The chemistry of heat transfer” and “How to design a life-saving system.”
Third-year computer engineering major Chloe Gao asked the middle schoolers to work with their hands as well as their minds to build a circuit powered by a 9-volt battery that lights an LED bulb.
Third-year electrical and systems engineering major Sofia Luis explained how machine learning works by showing how a computer program could distinguish between visually similar yet distinct images of a toy bear and a toy beaver. The middle schoolers were encouraged to work together on projects to make the lessons more interactive.

Darrah Sheehan, a fourth-year biomedical engineering student in charge of middle school outreach for the Society of Women Engineers, said about 40 members worked the event as teachers, coordinators and greeters.
“We recruit female engineering students to teach a class of their interest,” Sheehan said. “It’s always something STEM-related, but it could be more of an aerospace focus, such as something about rocket ships, or it could be something forensic science-related.”
The engineering students selected their teaching topics, with the Society of Women Engineers providing any needed materials.
Biomedical engineering major Stella Perini and systems engineering student Abigail Crow taught the “How to design a life-saving system” class, which they explained was actually about problem-solving.
