The Warren County School System wants to purchase a large mobile STEM classroom in order to reach more children when the Mechatronics program expands into elementary schools.“We brought this to you last month,” said Director of Schools Bobby Cox. “We wanted time to compare the primary bid with the alternate bid. We feel like we need to go with the primary bid.”The primary bid is for $116,431 and the classroom can be used to teach 30 students at one time.
