The group that has the most years of data to graph will determine the scale that all groups will use. It is important to evenly space the years. Help advanced students determine an appropriate horizontal scale to use on the quadrille-ruled graph paper.
Have beginning graphing students label the horizontal axis of the graphing worksheet with the years their data encompasses. Have students determine how many lines they will need if they count by tenths and if they count by hundredths. Demonstrate that counting by ones on each line will not allow for accurate resolution of data. Determine scale by asking which place value (ones, tenths, hundredths, etc.) should be used. Placing the graph paper in portrait orientation allows for approximately 40 lined intervals. Determine the range of data by subtracting the maximum and minimum temperature values (e.g., 14.87-13.54=1.33). Help more advanced students determine an appropriate vertical scale to use on quadrille-ruled graph paper. For students just learning to graph points, use the pre-labeled graphing worksheet. Divide the data so that each group or individual has approximately the same number of data points. Depending on class size, the steps in “Procedures” can be done by individuals or groups of students. The data file for this activity contains 137 years of average global annual temperature measurements.

As such, we have provided two sets of procedures, one for grade five and one for high school. Note: This activity is aligned to education standards for fifth grade and high school grade bands. They will then determine whether global temperature is rising based on the data. In this activity, students will use global temperature data to create models and compare short-term trends to long-term trends.
