**Lesson Plan: Suspension System**
**Grade Level:** Senior Secondary 2
**Subject:** Auto Mechanics
**Duration:** 90 minutes
**Objective:**
By the end of the lesson, students should be able to:
1. Understand the basic principles and functions of the suspension system.
2. Identify the main components of the suspension system and explain their roles.
3. Explain different types of suspension systems and their applications.
4. Demonstrate basic troubleshooting techniques for suspension system issues.
**Materials Needed:**
- Whiteboard/Chalkboard and markers/chalk
- PowerPoint presentation
- Visual aids (e.g., diagrams of suspension systems)
- Sample suspension system components for demonstration (springs, shock absorbers, control arms, etc.)
- Handouts with key notes and diagrams
- Suspension system model or a car for practical demonstration (if available)
**Lesson Outline:**
1. **Introduction (10 minutes)**
