It's no secret that fewer and fewer women are entering computer science fields. Attracting high school girls to computer science is only part of the solution. Retaining them while they are in higher education or the workforce is also a challenge. To solve this, there is a need to show girls that computer science is a wide-open field that offers many interesting career choices. That's why the author decided to take a group of high school sophomores and juniors from Columbus School for Girls (CSG) in Ohio on a service trip to the Caribbean, where they delivered 60 laptops to three classrooms of third through fifth grade students and taught them how to use the computers. Her intent was to expose her students to computer science through a service trip and show them that this field has many fulfilling pathways. This project can easily be carried out in other private or public schools, either as an elective, after-school activity, or club. What works for girls will also work for boys and minorities, both of which have declining numbers in computer science in the United States. (Contains 6 online resources.)
