Is the globe warming? Is there evidence in the Great Lakes region?
Groups of students graph data reflecting temperature anomalies over a short period in the recorded climate history of the world or in part of the Great Lakes
region. Using only their own data, they predict how their actual temperature anomaly trend might continue; then student groups assemble and observe the
trend of the 130-year data set. In addition to the science of the lesson, important conclusions can be drawn about how the construction of a graph scale can
influence how data are interpreted.
