The document presents historical data and activities for students in grades 4-8 to research and explore the ethnocultural history of Humboldt County, California. Objectives are for students to identify unique geographical characteristics of their county and how these characteristics influence ways of living, examine relationships between American Indian and European cultures in the county, analyze the perspective of an American Indian toward European cultures and of a European settler coming to the county, identify an example of prejudice or unfair treatment of a group in the county, identify ethnocultural groups and their specific contributions, identify ways in which they are part of an ethnocultural group, and demonstrate positive attitudes toward membership in their own ethnocultural groups. Numerous reproducible materials include an ethnocultural time line, brief readings on many aspects of county history and development, maps, examples of architecture, directions and information for a walking tour, a chart for comparing occupations of ethnocultural groups, readings about unique individuals in the county, and a family tree chart. A test booklet and a model for creating a similar document for any community is also included. (KC)
