This four-lesson unit, designed for use with high school students, examines economic development in Africa. Lesson 1, "What Is Development?" has students investigating terms such as development, third world, North, and South. In lesson 2, "Resources and Culture," students learn that people define resources based on their own cultural perspectives. In lesson 3, "Mineral and Energy Resources," students learn about interdependence within the context of development. Students examine Zambia's economy and see the factors involved in managing mineral resources within the world economy. In lesson 4, "Resources for Self-Reliance," students examine more fully the paradox that much of Africa faces: it possesses enormous mineral resources and great agricultural potential, while at the same time has some of the world's lowest standards of living. Students learn about the need for African initiated resolutions and the difficulty of realizing them. A 20-item bibliography of resources concerning Africa and development issues is included. (DB)
