WCMS eighth-grader Chris Brown was literally “floating on air” after winning first place in his category with his handmade hovercraft at the Warren County school system county-wide Science Fair Thursday night. Though individual schools have held science fairs this is the first county-wide version in some time, according to Hands-on science instructional coordinator Diane Parton. The event was held at the Bridgestone Learning Center, and the five schools participating included Centertown, Dibrell, Irving College, Morrison and Warren County Middle School.Parton says she is pleased the school system has decided to revive the county-wide program because it provides motivation for students to get physically involved in science through developing their projects.“The kids have to do something hands-on when they do this and they’ve really learned a lot,” Parton said.
