This Instructional Activity is a part of the Lesson 9, Unit 6, Grade 8. Discuss the data presented in the table and scatter plot. Consider starting by asking if students are familiar with crocodiles and alligators and how they differ. Ask students if they can imagine what a bite force of pounds would feel like. Ask them if they know what body mass indicates. If students understand that body mass is an indication of the weight of a crocodilian and bite force is a measure of the strength of a crocodilian's bite, the data can be investigated even if they do not understand the technical definitions and how these variables are measured.
