Volunteers from a local business were among those participating in a recent project to build a new butterfly garden at Byrns Darden Elementary School in Clarksville, Tenn. The garden will serve as an outdoor classroom for lessons in science, technology, engineering and math. "STEM is about solving real world problems. We wanted to turn our courtyard into a learning environment. Byrns Darden students will learn that their dreams and plans can become reality with the work and the generosity of many kindhearted people in their community," said Ray Szczepaniak, the school's STEM leader.
