Assessment
During the discussions, help students come to consensus about each phenomenon. Students may suggest connections between phenomena such as the fact that increasing global temperatures may contribute to decreased Arctic Sea ice and increased sea level. They may also suggest more specific connections such as the decrease in Arctic Sea caused the sea level rise (although this idea is incorrect because sea level rise is attributed to melting land ice, it is appropriate to let them express any ideas at this point or to direct them toward formulating this as a question to include). Use the 2.1 Assessing the Finding Patterns Tool for Earth Systems to assess students’ completed tools.
