St. Cloud Times — The pendulum snake worked its undulating magic as a gaggle of students watched, mesmerized. The device is a lineup of pendulums, each progressively longer than the last, suspended from different heights so the weighted balls at the base of the pendulums are at the same height.
Haglin’s exhibit was one of many at Thursday’s 7th Annual STEM Summit at St. Cloud State. Its attendees were almost 1,500 middle and high school students from Central Minnesota.
The purpose: to get students excited about studying and working in STEM, or science, technology, engineering and math.
