Branch Elementary students make paper helicopters under the direction of Mickey Bowen, 412th Test Wing Science, Technology, Engineering and Mathematics outreach director. Bowen taught the students how a helicopter flies. After they folded their papers into a helicopter shape the students dropped them to see how they twirled to ground. The children got an up close and personal education experience during the 3rd Annual Branch Elementary School Science Carnival May 3, 2011. (Air Force photo by Kenji Thuloweit)
