Unit 9, Lesson 5
Plotting the Temperature (Optional)
Grade 8
Preparation
Lesson Narrative
In this second in the sequence of optional lessons, students construct a mathematical model to investigate if there is an association between latitude and temperature (MP4). The lesson begins with an example of a scatter plot and how to talk about associations seen in data. Then students create and answer questions about the data they gathered or the data provided in the lesson. In either case, students create a scatter plot of the data and approximate a line of best fit. They must make decisions about reasonable values when creating their axes and interpreting the data (MP2).

Required Preparation
None
Modify the Activity Synthesis of the Warm-up by engaging students in a discussion about drought conditions in California and other parts of the nation and world. Invite students to research the causes and effects of droughts, as well as possible solutions. Students can begin research at the U.S. Drought Monitor (https://droughtmonitor.unl.edu/) and share their findings with the class.
