This curriculum unit of the Muncie (Indiana) Southside High School is to simulate the dynamics of foreign currency exchange rates from the perspectives of: (1) a major U.S. corporation, ABB Power T & D Company, Inc., of Muncie, Indiana, a manufacturer of large power transformers for the domestic and foreign markets; and (2) individual consumers who purchase imported items. An interdisciplinary approach is used with a variety of skills to be enhanced. The unit is composed of four major parts: (1) introduction to ABB, exchange rates, and a map of Germany; (2) transformer manufacturing; (3) transformer cost and currency exchange; and (4) import and export-currency exchange.
