In this activity (on pages 23-29), partners use the Plant Traveler Cards, along with a world map and map worksheets, to follow plants such as cassava, chocolate and coffee that grew first in one part of the world and then spread to other parts. Learners also write a story about a plant traveler of their choice, and should be encouraged to use art supplies to enhance their maps. Tracing the global migration of plants teaches world geography, in addition to how humans have helped transplant crops.
