LESSON 18 – BIRDS AND REPTILES

Background:
Most reptiles hatch from eggs. Once they hatch, they take care of themselves. Birds also hatch from eggs but require help early in their lives. Mammals are born alive and need to drink mild from the bodies of their mothers.

Objective:
Describe the development of animals from birth to hatching to maturity
Comparing the amount of care needed by the young of several species.

Vocabulary: mammal, reptile, bird, category

Quick Peek: The children compare mammals with reptiles and birds.

Materials:
picture worksheet
categories worksheet
glue
scissors
crayons

Method:

1. Distribute the picture worksheet to each student.
2. Discuss: Which animals do you think are mammals? Which animals do you think are reptiles? Which ones are birds? How did you know?
3. Now distribute the definition pages and read together as each student follows along. Discuss. Were our thoughts about each animal correct? Did we put them into the right categories? How is each category different? Do the parents in each category care for their young once they are born? How do mammals care for their young? How do reptiles care for their young? Do birds care for their young once they are born?
4. Have the student colour, cut and paste each animal under the correct category.

*You may want to extend this even further by including amphibians and insects!
