The final portion of the lesson consisted of a role-playing game in which the students were split into groups representing each biome. The plant and animal fact cards were used as a reference in each group in addition to water and sunlight graphs that the older students help make. Students took turns rolling the die and then a question would be read from a deck of cards from the corresponding category. Categories included Human Impact, Natural Disturbance, Climate Change, Plant Mix-Up, and Animal Mix-up. Each card had a scenario that was read to the students, and the students had to determine what the associated impact on the biome and its plants and animals would be. Students seemed to really enjoy this role-playing exercise, and were able to establish some very feasible answers exercising their critical thinking skills.
The students especially liked the Plant Mix-Up and Animal Mix-Up scenarios because they consisted of questions such as, “What would happen if an elephant moved to the desert?” or “Would a grey wolf be able to survive in the tundra? What would happen to the Arctic wolves?”. Students were able to develop sensible answers to these questions, discussing with one another about the needs of the given plant or animal and whether or not it could survive in a different environment. With some guidance they were able to determine the consequences of relocating animals and plants not only on the individual organisms but on the plants and animals of the new ecosystems to which they were introduced.
