Sunday school, Manzanar War Relocation Center, 1943. Photographed by Ansel Adams.

Sunday School is a kind of schooling found in many churches or other Christian communities. Classes are done on Sundays. Before or after the main part of worship, a class is held to learn more about that church's teachings and about the Bible. Sometimes the class is only for children, sometimes adults go there as well and sometimes there are different classes for adults and for children.
