#### Grade Level: Senior Secondary 1
#### Duration: 60 minutes
#### Subject: Auto Mechanics
#### Topic: Cooling System II
---
### Objectives:
By the end of this lesson, students will be able to:
1. Describe the components of an automotive cooling system.
2. Explain the role and function of each component in the cooling system.
3. Identify common issues that can arise in a cooling system and their solutions.
4. Demonstrate basic maintenance and troubleshooting procedures for cooling systems.
### Materials Needed:
- Chalkboard/Whiteboard and markers
- Handouts with diagrams of cooling system components
- A model or real life example of a car's cooling system
- Projector and computer for video demonstration
- Basic tools for inspection and maintenance (wrenches, screwdrivers, etc.)
- Coolant and radiator components for demonstration
### Introduction (10 minutes):
1. **Welcome and Introduction**
- Greet the students and briefly review the previous lesson on the basics of cooling systems.
2. **Learning Objectives**
- Outline the objectives for today's lesson.
3. **Engagement Question**
- Ask students: Why is it important to maintain a vehicle's cooling system?
### Instruction (15 minutes):
1. **Review Components of an Automotive Cooling System**
- Use the whiteboard to list key components: Radiator, thermostat, water pump, cooling fan, hoses, coolant.
2. **Detailed Explanation of Components**
- Discuss the function of each component:
- **Radiator**: Cools the coolant that has absorbed heat from the engine.
- **Thermostat**: Regulates the flow of coolant to the radiator.
- **Water Pump**: Circulates coolant through the engine and radiator.
- **Cooling Fan**: Helps cool the radiator when the vehicle isn't moving fast enough.
- **Hoses**: Carry coolant between the engine, radiator, and other components.
- **Coolant**: Absorbs heat and transfers it to the radiator.
### Demonstration (15 minutes):
1. **Video Demonstration**
- Play a short video demonstrating how the cooling system works.
- Pause the video at key points to explain what's happening.
2. **Hands-on Demonstration**
- Use the model/real-life example to show the actual components.
- Demonstrate basic maintenance like checking coolant levels, inspecting hoses, and testing the thermostat.
### Activity (15 minutes):
1. **Group Activity: Identifying Components**
- Divide students into small groups and give each group a handout with a blank diagram of a cooling system.
- Have them identify and label each part.
2. **Troubleshooting Scenario**
- Present a common issue (e.g., overheating engine).
- Ask students to discuss in their groups what might be causing the issue and how to fix it.
### Discussion and Q&A (5 minutes):
1. **Discussion**
- Facilitate a class discussion about the activity.
- Share correct answers and explanations for the troubleshooting scenario.
2. **Q&A Session**
- Open the floor for any questions about the day's lesson.
### Conclusion (5 minutes):
1. **Recap**
- Summarize the key points of the lesson.
- Reinforce the importance of regular maintenance and understanding cooling system components.
2. **Homework Assignment**
- Assign students to observe and write a one-page report on the cooling system of a vehicle at home or in the community, focusing on any visible components or possible issues.
### Assessment:
- Participation in group activities and discussions.
- Accuracy in labeling the diagram.
- Quality of solutions proposed during the troubleshooting activity.
- Completion and quality of the homework report.
