The increase in amphibian deformity rates and decline in amphibian populations throughout the world has become an issue of great concern. This hands-on card game simulates a frog population of a local pond under both natural- and human-influenced situations. As the game progresses, students will see first-hand how quickly a frog population can be affected by various factors. The cycles of the frog population are modeled, graphed and further researched. Includes complete Teacher Notes, reproducible student handouts and enough materials for five groups of students.
