Oh, for a bit of wrought iron. Using tried-and-true triangular trusses — a staple of high-quality engineering the world over — high school girls, under the watchful eye of Lesley Olson (center), a junior in chemical engineering in the School of Engineering & Applied Science, compete to erect the tallest marshmallow and toothpick tower during Engineering Olympics Feb. 25 on the final day of Engineering Week. The girls — (from left) Kaity Parsons of Fort Zumwalt North High School; Jennifer Chen of Fort Zumwalt West High School; Olson; Jasmine Hyatt of Edwardsville High School; Ginnie Kim of Thomas Jefferson School; and Rachel Rone of Notre Dame High School — were hosted for a day of engineering by the Society of Women’s Engineers. EnWeek began Feb. 19 (below) with a meet-and-greet in fashionable decorated hard hats, like the one to which sophomore engineering student Emily Storey is giving finishing touches. Other activities throughout the week included Lego engineering, "Capture the Flag" with Nerf guns and a paper airplane competition.
