This document provides information about classifying animals into vertebrates and invertebrates. It discusses the key characteristics used to classify animals, such as having a backbone. Examples are provided of common vertebrates like cows and invertebrates like jellyfish. Students are asked to identify vertebrates and invertebrates from a list of animals and to identify the major groups of invertebrates like molluscs and arthropods. As homework, students are to write out a classification diagram and provide examples.
