Science, Technology, Engineering and Math are going on the road as part of the STEM on Wheels program, an initiative made possible by a $200,000 Perkins Reserve grant to introduce Warren County students to basics in advanced technology.“It is a trailer that will be traveling around to our county schools teaching STEM innovators and STEM designers to our seventh- and eighth-grade students,” said Tracy Risinger, Career and Technical Education director for Warren County. “They will learn concepts related to mechatronics, STEM, robotics and advanced manufacturing.”The STEM on Wheels trailer arrived at Centertown School this week and students were given their first glimpse at its teaching tools which included a 3-D printer, one of which each school will get to keep. The concept of 3-D printers is that they can make – in the case of the printers that are being given to the schools – an object as it is drawn on a computer program.
