With the help of volunteer engineers from the American Council of Engineering Companies (ACEC) of Washington, nearly 100 Girl Scouts from throughout Puget Sound tested their engineering prowess - in the form of individually designed model bridges built with wooden stir sticks and glue - against a stress-testing device designed specifically for the event.

The purpose of the program is to encourage an interest in math and science among the participants, and this year’s record-breaking winners show that Tiny Truss is moving toward its goal. Many of the would-be engineers were returning competitors, and improved on former bridge designs to shatter the record of 148 pounds.

The month-long program fosters girls’ continuing interest in math and science. Studies show that without direct support from parents, teachers and mentors, most girls lose interest in science at the elementary school level. Building the trusses also provides an opportunity for the Girl Scouts to work with their parents and guardians in engaging, problem-solving activities. The father of one of last year’s participants lauds the program as a dynamic exercise of focus, imagination and critical thinking.

Leading up to the competition, volunteers from ACEC offered the Girl Scouts training workshops, introducing them to the engineering principles used to design and build trusses and bridge structures. ACEC supplied each of the participants with a kit containing instructions and wooden coffee stir sticks to create their trusses.

The event was held on April 24 at the Pacific Science Center in Seattle.
