Animal Classification
Purpose: Classify animals according to skeletal structure, method of fertilization and reproduction, body coverings, and locomotion.
Background: Classication of animals is a way to group them based on similar traits. This is an important way to see how animals are related to each other. They are separated into groups using traits or characteristics (like whether they have a backbone or not). The way we classify animals and plants was created by a scientist named Linnaeus. The Linnaeus system classies plants and animals on seven levels, using Latin and Greek words. With the development of genome science, the biological connection between animals is beginning to alter and animals are being more accurately classified. The classic Linnaeus system which can be shown in the following way. All living things are classied on the seven levels: Kingdom Phylum Class Order Family Genus Species An example of how this works in an Eastern Chipmunk is: Kingdom Animalia animal Phylum Chordata has backbone Class Mammalia has backbone, nurses young Order Rodentia has backbone, nurses young, long, sharp front teeth Family Scuridae has backbone, nurses young, long, sharp front teeth, bushy tail Genus Tamias has backbone, nurses young, long, sharp front teeth, bushy tail, climbs trees Species striatus has backbone, nurses young, long, sharp front teeth, bushy tail, climbs trees, stripes

Animal Classification Activity
Directions: 1. Study the twelve animals pictured on the handout. 2. Number your notebook paper 1-12. 3. Describe each animal next to its corresponding number on your notebook paper based on its characteristics you observed. 4. Answer the following questions on your notebook paper: How are these animals similar? How are these animals different? How can these animals be classified into groups? 5. Use the Dichotomous Key to identify each of the twelve animals in the pictures. 6. Write the name of the animal on your notebook paper next to its corresponding number and descriptions from #3.
