Two hundred kids from seven Valley schools participated in a STEM (science, technology, engineering and math) event Tuesday at the Arizona Science Center.
Activities focused on what engineers do, how they use technology and what science they need to know to create the gadgets, tools and technologies we so gleefully use every day. The event, called “All hands on STEM,” was part of NBC’s Education Nation tour that rolled through town this past week. (The rest of the media was in town for that trial, which had nothing to do with education, did it?)
At one table, students watched a cow’s eye being dissected, adding a different kind of E — Ewwww! — to the STEM acronym. The kids found it riveting, though it grossed out others (me).
Other activities involved measurement, aerodynamics, strength of materials and shapes, communication, spatial visualization, structures, trial and error and fun stuff like freezing balloons in liquid nitrogen.
After visiting all the stations, the kids trooped into the sunshine, where students from Tarwater Elementary launched air pressure-fueled water bottle rockets.
