The Water in Africa Project was realized over a 2-year period by a team of Peace Corps volunteers, World Wise Schools (WWS) classroom teachers, and WWS staff members. As part of an expanded, detailed design, resources were collected from over 90 volunteers serving in African countries, photos and stories were prepared, and standards-based learning units were created for K-12 students. In this unit, middle school students compare the division of labor around water-related work in rural Lesotho to that of their own household. Water provides an excellent lens through which to understand gender roles. The unit aims to have students gain an understanding of the multiple factors that influence how gender role formation takes place in different societies. It culminates with students writing letters in the voice of visitors to the United States from Lesotho. It can be used in geography and language arts classes. Five 45-minute class periods are suggested for completion. The unit lists materials needed, outlines applicable standards, poses discussion questions, and lists student objectives. It details day-by-day procedures for the teacher. (Includes several photos of inhabitants of Lesotho.) (BT)
