The document consists of five social studies units for developing basic inquiry skills at the secondary level. Students read and analyze data through the construction of a table and a graph in Unit I, "Reading Graphs and Charts." Topics include a model of consumer demand, census information, and national budgeting. In Unit II, "Community Change," students use maps as data sources for investigating community change. Students are given a city directory, map, and yellow pages directory for 1958 and 1978 from which they list and evaluate reasons for change. Materials from the city of Oxford, Ohio are included. Unit III contains a Civil War packet including maps of resources, important cities, agriculture, industry and manufacturing, and railroad maps. In examining the maps, students determine the conditions present at the onset of conflict, and reasons and strategies employed by the Union and Confederacy. Unit IV, "Finding Foreign Products in Your Home and Community," involves students in collecting data and transferring it into circle graphs. Students also identify on a world map countries producing materials. Unit V, "Cartoon Reading," presents three political cartoons for students to analyze according to a headline story. (KC)
