Some area students are hoping to make a difference in the lives of children fighting for their lives. Budding artists in Betty Wiedenbein's 4th-grade class are painting butterflies on glass rocks to support children with brain tumors. Why butterflies? They are the emblem for Nationwide Children's Hospital in Columbus. The project came about as part of a growing non-profit "Rockin' on the Run" to bring awareness and research to pediatric brain tumors.
