The lessons in this issue address the questions: “What are the limits on how big or small an animal can be?” and “What effect does an animal’s size have on the animal itself?”
There is a discussion of the ways large animals differ from small ones, with a focus on metabolism and body temperature. Two activities ask students to use background information and a chart to compare the size and other characteristics of a shrew to that of an elephant. Another activity involves students in “creating” their own animal in the form of a cube of marshmallows in order to introduce the subjects of surface area and body temperature. An activity sheet features an illustrated chart of numerous animal size differences.
