Grade 3-4, Life, Vertebrates Unit
The book Vertebrates identifies common characteristics of vertebrates, including bone structure and major parts of the skeleton. The book organizes vertebrates into five classes-mammals, birds, fish, reptiles, and amphibians-and explains how each class can be distinguished from the others. These differences include body covering, body temperature, means of breathing, birth method, and other distinguishing features. Examples of animals in each class of vertebrates are provided.
