CHAPEL HILL — Wise Elementary students returned to class Friday after a small fire disrupted activities Thursday at the Chapel Hill school. The fire erupted in a classroom early Thursday morning. It looked as if it had been smoldering all night. Firefighters worked to remove the smoke that formed in the room and had drifted into other parts of the building. Students were sent home, and classes were canceled for the remainder of the day at the school in the 10000 block of Highway 64.
