### Subject: Auto Mechanics
### Level: Senior Secondary 2
### Duration: 90 minutes
---
## Objectives:
By the end of the lesson, students will be able to:
1. Define engine lubrication and its importance.
2. Identify the types of lubricants used in engines.
3. Explain the working principles of engine lubrication systems.
4. Describe the components of an engine lubrication system.
5. Understand regular maintenance practices for engine lubrication.
## Materials Needed:
- Whiteboard and markers
- PowerPoint presentation
- Computer and projector
- Engine model or diagram
- Samples of different types of lubricants
- Handouts on engine lubrication systems
- Gloves and safety equipment for hands-on demonstration
## Lesson Breakdown:
1. **Introduction (10 minutes)**
- Greet students and take attendance.
- Engage students with a quick warm-up discussion on the importance of maintaining a vehicle’s performance.
- Introduce the topic: Engine Lubrication.
2. **Direct Instruction (30 minutes)**
- **Definition and Importance of Engine Lubrication:**
- Use a PowerPoint slide to define engine lubrication.
- Discuss the role of lubrication in reducing friction, cooling engine parts, preventing wear, and cleaning engine components.
- Show real-world examples or case studies of engine failures due to poor lubrication.
- **Types of Lubricants:**
- Explain different types of engine oils (e.g., synthetic, conventional, high-mileage).
- Discuss the properties of lubricants such as viscosity, additives, and ratings (e.g., SAE viscosity grades).
- Show samples of different engine oils.
- **Working Principles:**
- Use a simplified diagram to explain how the engine lubrication system circulates oil through the engine.
- Describe the oil flow, starting from the oil pump, through the filter, to the engine components, and back to the oil pan.
3. **Interactive Demonstration (20 minutes)**
- **Components of an Engine Lubrication System:**
- Present an engine model or a detailed diagram.
- Identify and explain the function of key components: oil pump, oil filter, oil galleries, oil pan, oil pressure gauge, and oil cooler.
- Conduct a hands-on demonstration, if available, to show students how these parts integrate into the system.
4. **Guided Practice (15 minutes)**
- **Importance of Regular Maintenance:**
- Discuss best practices for maintaining engine lubrication, such as regular oil changes, using the right type and grade of oil, and checking for leaks.
- Hand out maintenance checklists and guides for students to review.
- Pair students and have them discuss the frequency of oil changes and what factors might influence this.
5. **Assessment and Review (10 minutes)**
- **Quiz:**
- Hand out a short quiz or worksheet to assess understanding.
- Questions may include defining lubrication, identifying components, and explaining the importance of maintenance.
- **Review and Q&A:**
- Go over the answers with the class.
- Address any questions or common misunderstandings.
- Encourage students to ask questions and clarify any doubts.
6. **Closure (5 minutes)**
- Summarize the key points of the lesson.
- Assign a brief homework task, such as researching the recommended oil change interval for a specific car model.
- Give students a preview of the next lesson topic.
- Dismiss the class.
## Homework:
Students will research and write a short report (1 page) on the recommended oil change interval for a specific car model of their choice and what type of oil is recommended by the manufacturer.
