After handing out the graph paper, instruct the students to make a graph by properly labeling the two axes and plotting the information using the two sets of data. They must use two different colors when plotting the data. This will be the first time for the students to graph two sets of data on the same graph. Finally, the students must list on the back of the graph three observations they made during the activity about global warming. Students are able to plot two sets of data using two different colors, label the correct information on the graph, and makes two observations about global warming.
Students are able to plot the two sets of data and make one observation about global warming.
If there is an indication that some students are having difficulty with this activity and do not fit into any of these three categories, set aside time to assess what areas of weakness those individual students seem to be experiencing. After diagnosing the problem, allow the students to redo the graphing portion of this lesson plan.
