When Columbus sighted land in 1492, he had no idea of the impact European plants, animals, and diseases would have on the native species of the Americas. In return, animals and foods from the New World changed life for those in the Old. Imagine a time without chocolate! That was one of the items traded between our worlds in the Great Exchange. Examine the different kinds of exchanges made and how they had an impact on the cultures and lives of the people during that tumultuous period. (Grades 3-12)
