Interdisciplinary social studies units on land use and social action for eighth and ninth grade students are provided. Although specifically written for students living in Pinellas County, Florida, the units can be adapted easily for teaching about land use in general and/or land use in one's own community. The overall objective is to help students look at what is happening in their community and clarify their values and life-style aspirations. Specific unit topics include the concept of land use, an historical view of land use and planning, beach development and natural disasters, transportation, zoning, water supplies, distribution, wastes, and population. Objectives, materials needed, and teaching methods are provided for each unit. Teaching strategies suggested are varied. Short readings and audiovisual presentations are followed by classroom discussions. Students write short stories, speeches, poems, and songs; make collages and travel posters; analyze graphs and tables; examine case studies; conduct interviews with community people; take field trips; and role-play community situations. Pre- and posttests are also included. (Author/RM)
