Elementary school field trips are offered Monday through Friday at 10 a.m. and last about two hours. No more than three classes (classrooms) per day, comprised of a maximum of 90 students can be accommodated due to space and safety concerns. Each class will stay together and rotate among three learning centers. Please do not divide classes without first consulting site staff. Bring at least three adult chaperones, but no more than five per class, to assist with hands-on learning centers. Additional "drop-in" parents may not be able to participate with their children and are discouraged. Schools with more than four classrooms, or those with inclusion classrooms, should call the site to discuss options before making a reservation. Homeschool groups or programs may be required to meet a minimum number of participants to reserve programs. Please call 703-759-2771 with questions or concerns. Comfortable shoes and clothing appropriate for the weather are necessary. There is walking outdoors among buildings, and the mill is not heated.

Students tour three learning centers and learn how local 19th century producers and consumers — the farmer, miller and storekeeper — used natural, human and capital resources to their advantage.

Students tour three buildings — the mill, the barn and the general store. Students learn about the site’s rich engineering, commercial and social history. The program closely follows the Virginia Standards of Learning for Force, Motion and Energy. It provides opportunity for students to see and use simple machines. Download Learning Kit.

Lunch Facilities

If your schedule permits and you want to bring lunch, there are indoor and outdoor spaces available. In nice weather, we recommend the picnic area adjacent to the parking lot. In poor weather, the group can sit on the floor and eat in the historic barn.

Students should not bring snacks. There is no time to eat during the presentation.
