Instructional Materials

To deliver this lesson, the teacher will use the following materials: Whiteboard or chart paper, Markers or pens, Pictures or diagrams of vehicle internal parts.

Rationale for the Lesson

understanding vehicle internal parts is crucial for basic mechanical comprehension. This knowledge fosters problem-solving skills and appreciation for engineering principles, beneficial for future studies and everyday life.

Prerequisite/Previous Knowledge

The teacher will start by asking pupils what they already know about cars and how they work. A brief review of the previous lesson on vehicle parts will be conducted. A captivating image of a car engine will be shown to spark curiosity.

Lesson Content

What is the Function of Vehicle Internal Parts?

The main job of a vehicle’s internal parts is to work together to change fuel into energy that makes the vehicle move. Each part has its own specific task, and they all depend on each other.

Some of the Major Vehicle Internal Parts and Their Functions Include:

The following are some major vehicle internal parts and their functions:

1. Engine: The engine is the most critically vital part of a vehicle. It changes fuel into energy that makes the vehicle move. Think of it like the pedals on a bicycle.
2. Transmission: The transmission sends the power from the engine to the wheels. This lets the vehicle go at different speeds,like changing gears on a bicycle.
3. Radiator: The radiator cools down the engine. It does this by moving heat from the engine to the air. It’s like a cooling system to stop the engine from getting too hot.
4. Battery: The battery gives the vehicle electricity to start the engine and power other parts. It’s like a rechargeable power source.
5. Alternator: The alternator charges the battery while the engine is running and powers the electrical system. It’s like a generator that keeps the battery charged.
6. Fuel Tank: The fuel tank holds the fuel the engine uses. It’s like a container for the vehicle’s fuel.
7. Exhaust system: The exhaust system takes away the waste gases from the engine and makes them less harmful. It’s like a pipe that carries away the waste.
8. Steering System: This system allows the driver to control the direction of the vehicle. It includes the steering wheel, steering column, and linkages that turn the wheels.
9. Braking System: This system is responsible for slowing down or stopping the vehicle. It includes brake pads, rotors, calipers, and brake lines.
10. Cooling System: This system regulates the engine’s temperature to prevent overheating. It includes the radiator, water pump, thermostat, and coolant hoses.

Lesson Keywords

• Engine – The part of a vehicle that converts fuel into power.
• Transmission – The part that transfers power from the engine to the wheels.
• Radiator – The part that cools the engine.
• Battery – The part that provides electricity to start the engine.
• Alternator – The part that charges the battery while the engine is running.
• Fuel Tank – The part that stores the fuel for the engine.
• Exhaust system – The part that removes waste gases from the engine.

Lesson Evaluation

To evaluate the learning, the teacher asks pupils to:

1. What is the main job of the engine in a vehicle?
2. how does the transmission help a vehicle go at different speeds?
3. Why is the radiator important for the engine?
4. What are two main jobs of the battery?
5. Explain how the alternator keeps the vehicle’s electricity working.

Assignment/Homework

1. Draw a simple diagram of a vehicle’s engine and label its main parts.
2. List three reasons why it is important to understand how vehicle parts work together.
3. Research and write a short paragraph about the function of the car’s air conditioning system.
