This curriculum unit is designed for secondary students in twentieth-century history and peace studies. The unit contains three activities from which students gain a better understanding of the dimensions of apartheid in South Africa. The activities are entitled: (1) "Racial Separation," an activity that gives students the opportunity to identify and research three distinct levels of social separation practiced in South Africa--"petty apartheid,""urban segregation," and "grand apartheid"; (2) "Images of Defiance," an activity where students are shown samples of Soweto Day posters and are asked to design and produce their own student protest posters; and (3) "South Africa: Free at Last!" an activity where students read an article concerning the triumph and challenges of South Africa's new multiracial government and then respond to questions.
