Calisphere: A World of Primary Sources

Here is a link to the University of California "Calisphere" site. This site has priamry source photographs on California history from 1848 to the 1970s. The photographs are divided into historical periods. Each section contains an brief overview of the period, questions for students to consider about the photographs, activities and worksheets.

Although the site focuses only on California history, teachers should find stuff they can use in a U.S. History class. For instance, the site has photos that relate to Western Expansion, the Chinese Exclusion Act, the Dust Bowl and the Depression, Japanese Internment Camps, etc.
