This unit is a different and fun way to engage students with an extremely important topic, climate change, which cuts across scientific and nonscientific disciplines. While climate change itself may not be listed in the curriculum of every science class, the authors contend that such a unit is appropriate for virtually any science curriculum. Classes that focus on Earth/space science and physical science lend themselves naturally to such a unit, due to the focus on big ideas that appear in each, such as radiation, temperature, phases, phase changes, and so on. Courses with a life science emphasis could easily incorporate a climate change unit with perhaps a change in emphasis to that of biogeographic distribution (e.g., polar bears). Also, this exploration into climate change emphasizes many of the scientific practices and crosscutting concepts stressed in the National Research Council's (NRC's) "A Framework for K-12 Science Education" (2011). The authors also suggest that the incorporation of an activity that lends itself to modeling the greenhouse effect may prove useful, particularly in stressing the scientific practice and crosscutting concept of scientific modeling.
