This photo was taken on the Girls & Science day I held at the high school in my village, in Guinea in the spring of 2012. As an optional activity, girls came together on a school holiday to take part in a day full of science demos, health seminars, and games. As part of one of their team building activities, the girls were instructed to form circles. Without instruction, they grouped up and held hands, smiling at one another, happy to be learning and discovering together.
