Build unity through secret acts of service.
Plan for each young woman at camp to have a “secret sister.” Before camp, assign a secret sister to each young woman or have each young woman choose a secret sister. To select secret sisters, you could put all the names of the young women into a paper bag. Invite each young woman to draw a name (she should not keep the name if she draws her own). Make sure every young woman, including visitors, is paired with someone. The young women should not tell anyone who their secret sister is. During camp, give acts of service, notes, or small and inexpensive gifts to your secret sister. You could share with each other your secret sisters at the end of camp as part of a devotional or other activity.
