A Detailed lesson plan in Automotive (Cooling system) I. OBJECTIVES 1. Identify and discuss the purpose and operation of cooling system. 2. Appreciate the significance of engine cooling system. 3. Apply the basic parts of cooling system learned in engine. II. SUBJECT MATTER Topic: engine cooling system Materials: visual aids, pictures, video. References: automotive mechanic, crouse-anglin,pp.315. III. PROCEDURE TEACHERS ACTIVITIES STUDENTS ACTIVITIES Good morning everyone! Good morning sir! What was our lesson last meeting? Sir it's all about lubricating system. Did you understand the past lesson? Yes sir. 2. MOTIVATION Teacher's activities Students activities Show a picture of engine What pictures do you see on the board? Very good! Sir it is an engine. Teacher's activities Student's activities How does an engine work? Yes student A. Sir an engine works through using a gasoline or diesel. Yes correct! Why an engine doesn't get overheated? Yes student B. Sir, based on what see on the boat and automobile, some of them uses water and even a purified water to maintain the temperature of engine. Correct! B. PRESENTATION Teacher's activities Student's activities. Today, we are going to discussed about an "engine cooling system". But before we are going to discussed, we will have an activity first. Posted on the board is a" word search puzzle". What you are going to do is to find words list on right. The words may appear horizontally, vertically, diagonally (backward/upward) When you find the words, circle it on the puzzle, then cross it off on the list. I will call five students to do the job or activity. Upon completion of the word search puzzle, participants be call to say something or explain the words they have encircled, based on what they understand. 4. ANALYSIS TEACHER'S ACTIVITIES STUDENTS ACTIVITIES What do you think the purpose of cooling system? Yes student A? Sir it keeps an engine in an Efficient ` temperature. . Yes, the cooling system keeps the engine At its most efficient temperature at all speeds And operating conditions. What will happen if this heat in an engine will Not taken away? Yes student B. Sir if this heat will not taken Away in engine, it will cause The damages parts in engine. Yes correct! This is one of the three jobs performed by The cooling system. Cooling system also Helps bring the engine up to normal operating Temperature as quickly as possible. TEACHER'S ACTIVITIES STUDENTS ACTIVITIES Now how the cooling system works? Yes student C? The cooling system works by sending The liquid coolant to the engine blocks and heads of engine. Very good! As student C said the cooling system send a Liquid coolant through the passages of the engine Blocks and heads. As the coolant flows through this Passages it picks up heat from the engine. This heated Fluid makes its way through the radiator, as it flows Through the thin tubes in the radiator this hot liquid Is cooled by the air stream, Once this fluid is cooled It returns to the engine to absorb more heat. There are five basic parts of cooling system to do The job in controlling engine temperature. What are those? Yes student A? Sir the five basic parts of cooling system are water pump, water jackets Thermostat, radiator and fun. As you can see the picture (present the picture) The cylinder block and cylinder head have internal Passages or water jackets, the coolant or antifreeze Flows through here and picks up some heat, and cool Cool the metal parts and it heats the coolant. And this is the job done by the water puma, Water pump pushes the hot coolant out of the water jackets And through the radiator. How the radiator works? Yes student B? Sir in the radiator the coolant Loses heat to the passing air. Yes the radiator is also called heat exchanger, it Has two sets of passages. One set is for the coolant And the other is for outside air. Once the coolant Flows here in the radiator the coolant loses heat To the passing air and flows back again through the water Jackets and pick up heat again. What is the purpose of thermostat? Yes student C? Sir the purpose of thermostat it Allows the coolant to flow. Yes very good. The purpose of thermostat is to controls the coolant flow. When an engine is cooled The thermostat closes to prevent the circulation to radiator. As the engine warms up the thermostat opens to allow coolant Flow through the radiator. What will happen if the thermostat failure? Yes student A? Sir the engine will get Overheated because the coolant Flows through here cannot circulate Will to the radiator. Yes very good! This is one also performed by the fan. Fan pulls or pushes outside air through The radiator. This improves engine cooling especially At idle low speed . 3. Abstraction TEACHERS ACTIVITIES STUDENTS ACTIVITIES Any question or clarification? No sir. Now we'll have an activity. Let's find out if you really Understand the lesson. I have here a "concept map worksheet" with a topic As the key word. What are you going to do is to think And write the words on the map that relate to the focal Word. I will call five student to write on every cluster the things that They have learned from the topic. Any question? None teacher. Water jackets Five basic parts of cooling system Water pump fan thermostat radiator 4. APPLICATION TEACHERS ACTIVITIES STUDENTS ACTIVITIES This time well have an activity I have here Pictures about the five basic parts of cooling system. What are you going to do is to put the names that Fit on the pictures and explain its operation. Five students will be called. IV. EVALUATION 1. What is cooling system? 2. What are the five basic parts of cooling system And explain each part? V. ASSIGNMENT For your assignment have a research more about engine cooling System. Use any automotive books or modules for your references. A SEMI-DETAILED LESSON PLAN IN AUTOMOTIVE 1. Objectives 1. Identify and discuss the purpose and operation of cooling system. 2. Appreciate the significance of engine cooling system. 3. Apply the basic parts of cooling system. II. Subject matter Topic: Engine cooling system Materials: visual aids, pictures, video References: III. Procedure A. PREPARATORY ACTIVITIES 1. Review Ask the class about the previous lesson. What they learn about in the previous lesson. Ask the students if they really understand the past lesson. 2. Motivation Ask the students to combine and paste the cut-out papers on the board. Ask the students what pictures they have formed. Ask the students why an engine doesn't get over heated. B. PRESENTATION 1. Activity Introduced to the students the "WORD SEARCH PUZZLE" Students will follow the instruction given in the activity. Students should explain based on what they understand. 2. Analysis Ask the students if they are familiar with the words search puzzle. Ask the students the purpose of cooling system. Ask the students how the cooling system works? Ask the students how water pump and water jackets works? Ask the students what is thermostat? Ask the students why the radiator called a "heat exchanger"? Ask the students what is the function of fan? 3. Abstraction Ask the students any clarification. Present to them a concept map worksheet with a topic in it as a key word. Ask the students to think and write the words on the map relate to the focal 4. Application word. Ask the students to locate the five basic parts of cooling system in engine. IV. EVALUATION 1. Explain cooling system. 2. What are the five basic parts of cooling system and explain each part? V. ASSIGNMENT For your assignment, have a research more about engine cooling system. Use any automotive books or modules for your references.
