Lunenburg Public Library's Saturday STEM program created an engineering challenge too try and build a dog sled that they raced down a ramp to see how well it was built. The idea was to build it with popsicles sticks, tape, straws, scissors and pipe cleaners. They were to build it so that it could hold small pom poms. Roberto Cespedes and his son Jabez Cespedes, 6, works on their sled together during the program. SENTINEL & ENTERPRISE/JOHN LOVE
