Lesson Plan: Animal Bodies as Systems

Discipline: Biology

Grade Level: 6th Grade

Lesson Duration: 6 periods (45 minutes each, total 270 minutes)

Content Topic: Animal Bodies as Systems

Methodology: Active Methodology

Objectives:

• Evaluate how survival needs of animals are met by systems working together.
• Identify and describe the basic functions of animal body systems.
• Explain how different body systems interact to perform specific functions.
• Compare and contrast the body structures of different types of animals.
• Analyze how the nervous systems of mammals respond to stimuli.

Standards:
