Ethnic Discovery is an approach to exploring cultural diversity with schoolmates, teachers, and friends, conceived and developed by the Boston Children's Museum. Ethnic Discovery experiments with possibilities for personalizing the process of social study. Students and teachers who participate in its activities learn about their own cultural heritages and family histories, about the ethnic dimensions of their own life styles, about the cultural identity of the communities in which they live, and about one another. The Ethnic Discovery process consists of two principal components: finding things out about one's own background, and finding out what one's cohorts have been finding out about theirs. The core of the Ethnic Discovery process is a set of activities which focus on the self, family, neighborhood, and community. Some of these activities, which are presented in this teacher's guide, are: activities to achieve self awareness and awareness of others; student research projects on their own names; a map exercise in locating students' residences and paths of travel; and other activities focusing on students' ancestry and family histories.
