# Senior Secondary 1 Auto Mechanical Lesson Plan
## Topic: Lubrication System
### **Objective:**
By the end of the lesson, students should be able to:
1. Understand the importance and function of the lubrication system in an engine.
2. Identify the components of a lubrication system.
3. Explain how a lubrication system works.
4. Conduct a simple maintenance check on a lubrication system.
### **Duration:**
90 minutes
### **Materials:**
- Diagram of a lubrication system
- Engine oil
- Oil filter
- Lubrication system components (oil pump, oil cooler, etc.)
- Hand tools
- Projector and computer for video presentation
### **Lesson Outline:**
#### Introduction (10 minutes)
- Briefly introduce the topic.
- **Teacher:** "Today we will discuss the lubrication system, a vital part of any engine. Can anyone tell me why lubrication is important in an engine?"
- Engage students in a quick Q&A to assess their prior knowledge.
- Show a short, engaging video clip about the basics of lubrication in engines.
#### Lecture and Discussion (20 minutes)
- Explain the importance and function of a lubrication system.
- **Teacher:** "The main purpose of the lubrication system is to reduce friction and wear between moving parts of an engine. It also helps in cooling the parts, preventing rust, and cleaning the engine components."
- Discuss key components of a lubrication system:
- Oil pan/sump
- Oil pump
- Oil filter
- Pressure relief valve
- Oil cooler
- Lubrication paths
- Use a projector to display diagrams and images to visualize each component.
#### Practical Demonstration (30 minutes)
- Demonstrate how to perform a simple maintenance check on a lubrication system.
- Check the oil level.
- Examine the condition of the oil.
- Replace the oil filter.
- Inspect the oil pump.
- **Teacher:** "Let's start with checking the oil level. Always ensure the engine is off and has cooled down before checking the oil. This is to avoid any potential accidents and to ensure accurate measurement."
#### Hands-On Activity (20 minutes)
- Divide the students into small groups and provide them with the necessary tools and lubrications system components.
- Instruct them to perform a basic oil level check and demonstrate the steps to replace the oil filter under supervision.
- Circulate around the groups to provide assistance and answer questions.
#### Review and Q&A (10 minutes)
- Recap the key points of the lesson.
- Ask students to explain the steps involved in a lubrication system maintenance check.
- Address any questions or misconceptions.
### **Assessment:**
- Observe students during the hands-on activity to ensure understanding and proper technique.
- Conduct a short quiz with 5-10 questions at the end of the class.
### **Homework:**
- Assign students a research task to write a one-page report on different types of engine oils and their specific uses.
