In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests. This will help learners discover how living and non-living ecosystem components influence each other. Learners will make their predictions by circling the areas that they think are rainforests on a blank map. Then, educators will reveal a sequence of maps so that learners can see how close they were to locating tropical rainforests. This lesson includes extension ideas, background information, and is standards-based.
