Kasich was scheduled Thursday to sign the measure about an object called the Adena Pipe. The prehistoric effigy pipe was linked to the ancient Adena culture and was found in 1901 in a burial mound near Chillicothe.
Students at the Columbus School for Girls fought for the measure for several years. Fourth-graders at the school began working on the proposal in 2009. Subsequent classes kept pushing it as they learned about the legislative process and the political system.
