Conduct a “human graph” activity to reflect students’ current opinions on climate change. In a large, open area, like the gym, post a series of signs on one wall, about 1.5 meters (5 feet) apart, saying, “I strongly agree,” “I agree somewhat” and “I do not agree” (or whatever measurement indicators you choose). You read a series of statements, and the students line up in front of the sign that indicates their opinion, forming a human bar graph. Here are some sample statements: I can’t do much about climate change. Climate change is the biggest threat we face in the twenty-first century. The worry about climate change is overblown. You could change the indicators to “Always,” “Sometimes” and “Never” to measure students’ environmental practices, such as using waste-free lunches, turning off lights and computers, not idling the car, and so on.
