Students in Robbi Giuliano's fifth grade class sit on yoga balls as they complete their assignments at Westtown-Thornbury Elementary School Monday, Feb. 4, 2013, in West Chester, Pa. By making the sitter work to stay balanced, the balls force muscle engagement and increased blood flow, leading to more alertness. (AP Photo/Matt Rourke)
