The Delaware Department of Natural Resources and Environmental Control will host various environmental display and activities at this year’s Delaware State Fair, set for July 19-28 at the Delaware State Fairgrounds, 18500 S. Dupont Highway, Harrington.

Under this year’s theme, “DNREC — Your ECOnnection,” DNREC’s displays link visitors to environmentally-friendly programs and ideas. Fairgoers will find information and activities from DNREC’s divisions and programs. Featured this year at the fair: DNREC’s Energy House and an interactive watershed display demonstrating how water flows and wetlands hold water that includes a 3D map of stormwater runoff from a suburban yard draining into Delaware’s wetlands, rivers, streams, bay and the ocean. Fair visitors also are invited to play DNREC’s scavenger hunt game for discovering eco-friendly facts about Delaware that can be found within the DNREC building and to pick from a wide range of prizes after their “hunt.” Visitors also can “get a charge” from DNREC’s Division of Climate, Coastal & Energy’s mobile solar panel display and charging station, known as T-Rex, located in front of the DNREC Building, on July 19-24.

Meanwhile, the DNREC On Stage theater will offer a preview of programs from parks, nature centers and other facilities statewide owned and operated by the Department’s Divisions of Fish & Wildlife, Parks & Recreation and Watershed Stewardship.

Fairgoers can learn more about the science behind the work DNREC does in protecting the environment and Delaware’s natural resources. DNREC’s building includes displays, hands-on activities and educational games. At DNREC on Stage, in the building’s air-conditioned theater, attendees will also see live animal shows and presentations ranging from maritime history to geology to Delaware’s unique plants and animals.
