## Lesson Plan: Transmission System III
### Subject: Auto Mechanical
### Grade Level: Senior Secondary 2
### Duration: 90 minutes
---
### Lesson Objectives:
By the end of this lesson, students will be able to:
1. Describe the components of the transmission system.
2. Explain the working principles of different types of transmissions (manual, automatic, and CVT).
3. Identify common issues and maintenance practices for transmission systems.
### Materials Needed:
- Whiteboard and markers
- Projector and screen
- PowerPoint presentation on Transmission Systems
- Sample transmission components (if available)
- Handouts with diagrams of transmission systems
- Tools for demonstration and inspection (optional)
- Quizzes or assessment sheets
### Lesson Outline:
#### Introduction (10 minutes)
1. **Greeting and Attendance:** Take attendance and greet students.
2. **Recap Previous Lesson:** Briefly recap what was covered in Transmission System II to build continuity.
3. **Warm-up Question:** Pose a question like “What do you think happens inside the car when you shift gears?” to engage students and stimulate thinking.
#### Presentation (20 minutes)
1. **Components of the Transmission System:**
- Use a PowerPoint presentation to explain the main components of the transmission system (gearbox, clutch, drive shaft, differential).
- Show diagrams and real parts if available.
2. **Types of Transmission:**
- **Manual Transmission:** Explain the structure and how it works, showing a diagram.
- **Automatic Transmission:** Describe how it differs from manual, the role of the torque converter, planetary gears, and hydraulic clutches.
- **Continuously Variable Transmission (CVT):** Introduce CVT, explaining the concept of variable gear ratios and its efficiency benefits.
#### Explanation and Demonstration (30 minutes)
1. **Detailed Working Principles:**
- Walk through the step-by-step process of how each type of transmission functions while shifting gears.
- Use animations or video clips to enhance understanding.
2. **Common Issues and Maintenance:**
- Discuss common issues (e.g., transmission slipping, hard shifting) and their symptoms.
- Explain basic maintenance practices, such as checking transmission fluid, and the importance of regular servicing.
3. **Hands-On Demonstration:**
- If possible, allow students to inspect a sample transmission or components.
- Demonstrate how to check fluid levels and other basic maintenance steps.
#### Q&A and Interactive Discussion (10 minutes)
- Encourage students to ask questions and engage in discussion.
- Use real-life examples or case studies to illustrate points.
#### Activity (20 minutes)
1. **Group Activity:**
- Divide students into small groups.
- Provide each group with a handout containing different scenarios of transmission system issues.
- Ask each group to diagnose the problem and suggest a solution.
2. **Presentation by Groups:**
- Each group presents their findings and proposed solutions.
- Facilitate discussion and provide feedback.
#### Conclusion (5 minutes)
- Summarize key points from the lesson.
- Answer any remaining questions.
- Provide a preview of the next lesson.
#### Assessment (15 minutes)
1. **Quiz:**
- Distribute a short quiz based on today’s lesson.
- Questions should cover the key objectives: components, working principles, types of transmission, and common issues.
2. **Review Answers:**
- Go through the quiz answers with the class, discussing any misunderstandings.
### Homework:
- Assign a reading from the textbook or an article about advanced transmission technologies.
- Ask students to prepare a short essay on “The Future of Transmission Systems in Automotive Engineering.”
### Follow-Up:
- Review the graded quizzes and provide feedback in the next class.
- Prepare additional hands-on activities or lab sessions to reinforce theoretical knowledge.

### Notes for Teachers:
- Ensure all safety protocols are followed during hands-on activities.
- Use a variety of teaching methods to cater to different learning styles (visual, auditory, kinesthetic).
- Encourage students to share their experiences or questions about vehicles they or their families own.
