- Clutch
- Gearbox
- Drive Shaft
- Differential
- Universal Joint
- Axles
- **Explanation & Diagram:** Show diagrams and explain the function of each component.
- **Clutch:** Connects and disconnects power from the engine to the gearbox.
- **Gearbox:** Adjusts the power and speed to the vehicle's needs.
- **Drive Shaft:** Transmits power from the gearbox to the differential.
- **Differential:** Distributes power to the wheels and allows them to rotate at different speeds.
- **Universal Joint:** Allows flexibility in the drive shaft.
- **Axles:** Transmit power from the differential to the wheels.
- **Incorporate Questions:** Engage students by asking questions related to the presentation.
#### **3. Guided Practice (20 minutes)**
- **Activity:**
- Distribute handouts with blank diagrams and labels.
- Group students and have them collaboratively label the parts of a transmission system.
- Utilize the model (if available) to give a hands-on demonstration.
- Discuss the answers as a class, ensuring comprehension.
#### **4. Independent Practice (20 minutes)**
- **Worksheet:**
- Provide students with a worksheet where they match components with their functions.
- Include a short scenario-based question that requires students to identify which part of the transmission system might be malfunctioning based on symptoms described.
#### **5. Assessment (5 minutes)**
- **Quick Quiz:** Conduct a short quiz using multiple-choice and short answer questions to assess understanding.
- Example questions might include:
- What is the primary function of the clutch?
- Where is the differential located?
- Explain in one sentence the purpose of the drive shaft.
#### **6. Conclusion (5 minutes)**
- **Recap:** Summarize the key points of the lesson.
- **Questions:** Allow students to ask any questions they might have.
- **Homework:** Assign a short essay on the importance of transmission systems in vehicles, focusing on their role in the overall functioning of a car.
### **Homework:**
- Write a 500-word essay on the importance of the transmission system in vehicles, including its impact on vehicle performance and fuel efficiency.
### **Reflection:**
