Starting Sept. 4, drop in during visiting hours to learn about the Biodiversity Education Center, Coppell Nature Park and the seasonal programs offered. While you're here, learn about the local environment through self-guided activities and interactive resources. Then, take what you learn out on the trails to become true EcoExplorers! Check our Facebook page for weekly themes. EcoExplorer is open to all ages, but children must be accompanied by an adult. Free admission. Every Tuesday, Thursday, and Saturday, from 9 a.m. to noon.
