### Lesson Plan: Transmission System Components II
**Grade Level:** Senior Secondary 3
**Subject:** Auto Mechanical
**Duration:** 60 minutes
#### Objectives:
1. **Cognitive:**
- Understand the function of various components in the transmission system.
- Identify and describe the secondary components of a transmission system.
- Comprehend the working principles and interactions among transmission system components.
2. **Affective:**
- Appreciate the importance of a well-functioning transmission system in automotive performance.
- Show willingness to engage in discussions and hands-on activities.
3. **Psychomotor:**
- Demonstrate the ability to identify and handle transmission system components.
- Perform a basic inspection and diagnosis of common transmission system issues.
#### Materials Required:
- Chalk/Whiteboard and markers
- Diagrams and charts of transmission system components
- Sample transmission system components (gearbox, clutch, driveshaft, etc.)
- Basic hand tools
- Multimedia projector (optional for video demonstrations)
- Worksheets and handouts
#### Lesson Sequence:
1. **Introduction (10 minutes)**:
- Begin with a brief review of the previous lesson on Transmission System Components I.
- Introduce the day's topic: "Transmission System Components II".
- Discuss the significance of a transmission system in an automobile's overall function.
- Outline the objectives for the lesson.
2. **Lecture/Explanation (20 minutes)**:
- **Overview and Functions:**
- Explain the purpose of the transmission system in the powertrain.
- Discuss the main function of the transmission system components: controlling the power and torque from the engine to the wheels.
- **Components Covered:**
- **Clutch:** Explain the structure, working principles, and types (e.g., diaphragm-spring clutch, coil-spring clutch).
- **Gearbox:** Describe different types of gear systems (manual, automatic, CVT), their components (gears, synchronizers, shafts), and how they work.
- **Driveshaft:** Discuss its function and importance in transmitting power to the wheels.
- **Universal Joints and Constant Velocity Joints:** Teach their roles in maintaining power transmission despite changes in angles.
- **Differential:** Explain how it allows wheels to rotate at different speeds while providing power.
- **Transfer Case (for 4WD systems):** Describe how it distributes power between the front and rear axles.
- Use diagrams, cutaways, or multimedia presentations to illustrate these components and their functions.
3. **Hands-On Activity (20 minutes)**:
- **Component Identification:**
- Divide the class into small groups.
- Provide each group with sample components and tools.
- Have students inspect, identify, and label each component.
- **Demonstration:**
- Demonstrate how to perform a basic inspection of a clutch and gearbox.
- Explain common issues that can occur and how to diagnose them.
4. **Group Discussion and Q&A (5 minutes)**:
- Facilitate a class discussion on the importance of each component and their interdependence.
- Address any questions or clarifications the students might have.
5. **Wrap-Up and Assessment (5 minutes)**:
- Summarize key points covered in the lesson.
- Distribute worksheets for students to complete as homework, which will include labeling diagrams, multiple-choice questions, and short answer questions on transmission system components.
- Provide information about the next topic: "Maintenance and Troubleshooting of Transmission Systems".
#### Assessment:
- Informal assessment through participation in hands-on activities and group discussions.
- Formal assessment through the completion of worksheets and a short quiz in the following class.
#### Homework/Extension Activity:
- Research a specific transmission system component and prepare a short presentation on how it works and common issues related to it.
#### Resources:
- Textbook: "Automotive Technology: A Systems Approach" by Jack Erjavec
- Online resources such as HowStuffWorks and YouTube for video demonstrations
- Automotive parts and repair manuals
