This interactive lesson introduces students to the various ways that people work to understand climate change, particularly in the Arctic. Scientists look for patterns within data sets to help them formulate research questions and then develop predictions that they can test. The Inuit peoples have been passing down climate observations from generation to generation. Students organize data on the observations of Sachs Harbour residents. They then think about climate change in their own community. They collect and summarize their own data, then form a testable prediction about climate change based on this data.
