A case study on Birmingham is presented in the first part of this resource unit on regional studies designed for fifth graders. The objective of the sequent occupance unit is to illustrate the impact which the discovery and utilization of a large natural resource, namely, iron ore, can have on the development of a city, in the hope that students will then generalize to other areas and resources. In the latter half of the unit students examine the region of the South as a whole, taking note of different characteristics in different parts of the South, and try to decide what criteria are used to set the South off from other regions of the country. The teacher's guide ED 062 226 provides program descriptions, course objectives, teaching strategies, and an explanation of format. Other related documents are ED 061 134, ED 062 227, and SO 002 732 through SO 002 741. (Several pages may be illegible.) (Author/SJM)
