Differentiation Have students work independently on plotting data points on individual graphs. Have the x-axis and y-axis already pre-labeled for students. Provide a handout of the data from the website. Provide sample pre-plotted data points on the graph to help get students started. Modifications Extending the Learning Assign students an independent or group research project to research patterns in arctic or Antarctic ice prior to 1979. Have students use the same website to graph the data from Antarctica.
