This 10-lesson unit blends social studies skills, concepts, and attitudes with language arts, art, and interpersonal relations in a 2-week study of cultures. Using a global perspective, students learn about four geographic regions of the earth (polar, temperate, tropical, desert), adaptation and change in the environment, different aspects of culture, and how natural resources and culture influence interdependence, standard of living, and utilization of technology. Children create imaginary countries and creatures capable of living in each particular environment. Group discussion regarding categories of data for each country (name, language, education, food, natural resources, population, climate, form of government, chief products, interdependence, transportation, national anthem) teach decision-making skills. Students also learn to organize data, paraphase, formulate paragraphs, and practice problem-solving techniques as they evaluate their "worlds." A vocabulary list and additional activities are followed by an extensive appendix of sample lesson materials, listings of consulates in the Seattle, Washington area, geographic definitions, pen pal and pairing addresses, and an ethnic calendar.
