One of Erie's schools is getting kids excited about STEM classes, while learning how to build race cars.  Central Tech hosted a STEM summer camp this week.  STEM stands for science, technology, engineering, and math.  Teams of students were involved in planning, design, manufacturing, analyzing, and marketing, as they built CO2 powered cars of the future.  The camp has been going on all week, but today was race day.  This week's camp is part of the "Go College" program.
