Click on Workshop 5 for additional materials supporting the one hour video for Workshop 5. In this video workshop, Jay Grenawalt shows his students at George Washington High School in Denver how extensive international trade is and how it improves our standard of living. Dr. Eric Gernant from the New York City High School of Economics and Finance illustrates how the ingredients in a single candy bar come from around the world. He also illustrates the gains from trade, using the law of comparative advantage. Finally, Elaine Schwartz has her students from Kent Place School in Summit, New Jersey, participate in a "banana wars" simulation that illustrates the unintended consequences of protectionism. The lesson plans provide a discussion guide, national standards, and activities for students.
