Send your class on an expedition through the rainforest! Along the way, they will write informational postcards to demonstrate what they've learned. Each team will be responsible for one of five rainforest regions. When they return from their research, groups share what they've learned with one another. Use Venn diagrams to compare the different regions as a class. The lesson uses ImageBlender, photo editing software designed for classroom use; however, the activities could be completed without the software.
