St. Henry Middle School seventh-graders Jason Balster, center, Harrison Wendel and Tyler Schwieterman, right, on Wednesday night explain the engineering design process they followed to create The Slagon, "a one-of-a-kind combination of a wagon and a sled." The annual STEM Fair Night at St. Henry Consolidated Schools attracted many community members. Students had to either create a new product or improve upon an existing product, middle school principal Kyle Kunk said. "They worked together. They had to do most of the work outside of class as far as constructing this."
