Science is a collaborative process and electronic means of communication enhance collaborative possibilities. It is an important ability to be able to effectively work with people from different cultures. Our program uses physics activities to bring secondary school girls from different cultures together. Students from a school in the United States and a school in Egypt worked over various media and completed activities designed by their teachers. The program goals are to develop cultural awareness, abilities to work with people who are different, distributed leadership skills, physics skills, and knowledge. This article will explain the overall approach of the program, describe one physics activity, and present evaluation data.
