The winner will receive a private group session (up to 25 people) in the National Zoo's "How Do You Zoo?" exhibit. This exhibit, designed for children ages 5 to 10 with parents, is a hands-on exhibit where children learn about animal care by role-playing jobs in a make-believe zoo. Available weekends between 10 a.m. and 3 p.m. At least one month's notice is required to schedule the group session.
