Look in the mirror
How many different social groups do you belong to? School is one kind of social group. Do you belong to other kinds of groups at school, such as a sports team? What other kinds of groups do you belong to at school or outside of school?

Investigate by interviewing
Interview someone in one or more of your own group affiliations (family, school, work, sports, etc.), and find out their affiliations--the different groups that they belong to. Map out the network of their connections and yours--are you connected to them in any other groups? How are their connections similar to or different from yours?

Research through reading
People in all cultures form communities. The most fundamental kind of community is the family. Because of our evolution as humans, we all belong to family groups--humans need to spend many years helping their young grow strong and learn how to live in the world. However, we organize into many different kinds of family groups depending on our environments, history, and creativity. What are some of the different kinds of family groups, also called kinship systems, that people throughout the world organize into? What are some of the reasons (environment, history, creativity) for these different types of family organizations? Here are some resources to help you do your research:
