Subject: General Science Topic: Vertebrates Subtopic: Mammals and their characteristics Class: Std III Time: 35 minutes Previous Knowledge: Children have seen some mammals. Objectives: Through discussion, and use of examples of mammals, children will be able to: a) Differentiate mammals from other vertebrates. b) Compose a list of characteristics of mammals. c) Acknowledge the importance of mammals to our environment. Concepts:

A characteristic is a special feature of an animal or thing. Mammals’ bodies are covered with hair or fur, are warm-blooded, breathe with lungs, they live on land, air and water. The young grow inside the mother and are born alive, mothers suckle their young (feed them with milk). Mammals can run, walk or swim. Some mammals lay eggs. Some are two-legged and some are four-legged. Some examples of mammals are: humans, horses, platypus, bats, and whales.

Linkages: 1. Social Studies – The conservation and the environment. 2. Language – Adjectives 3. Mathematics – Graphs and statistics

Skills: Writing a list of characteristics of mammals. Comparing mammals to other vertebrates. Identifying the importance of mammals to our environment.

Attitudes: Children will appreciate the importance of mammals in the environment.

Introduction:  Bring a small animal (mammal- hamster) to the class.  Ask children to observe the animal and write at least three features that they observe.  Ask children to name the group that this animal belongs. Development:  Introduce the term “mammal” to the class.  Teacher defines the term “characteristics” and writes a definition for class.  In groups of four, children are asked to list ten examples and ten non-examples of mammals.  Through guided questions ask children to state why the examples of mammals are indeed mammals and why the non-examples do not fit the category.

Closure: Recap the characteristics of mammals and examples and non-examples.

Conclusion: Children will be given a handout with ten pictures of animals. They will write whether they are examples or non-examples of mammals and they will justify their answers using the characteristics.

Extended Activity: Children can go on a “mammal hunt”. Take children around the compound or vicinity of the school and identify as many mammals as possible.
