PROCEDURES PowerPoint presentation Teacher-made Instructional Materials Youtube Video about Sound ENGAGE: Greetings Prayer Classroom Management Checking of Attendance Classroom Rules Good morning class! Good morning, ma’am. Did you eat your snacks? Yes ma’am. Before we start our lesson, kindly stand and (Students will pray) let’s pray. Arrange your chairs and kindly pick up those (Arrange their chairs and pick pieces of papers and plastics under your up pieces of paper and chairs. plastics under their chair.) You may now take your seats. Thank you ma’am. Secretary in each group, who is absent? (Secretary in each group will report who are absent in their group) As we go on with our lesson for today, please be reminded with our classroom rules. A. Reviewing Previous Lesson or Presenting the new lesson. Light is a electromagnetic wave which means that it doesn’t need a medium to propagate. Light travels in a straight path. Light is a form of energy made of photons. B. Establishing a purpose for the lesson. It will become hot ma’am. It will become hot also ma’am. Last meeting we learned about light. What is light? Very good. Light is an electromagnetic wave and it is a form of energy made of photons. Photons is the smallest unit of visible light. What do you think will happen to the pan on the top of the stove? How about to the metal spoon? What do you think will happen if I leave it in the pan with water? Let’s check if your answers are correct as we go on with our discussion. C. Presenting examples / EXPLORE: instances of the new lesson. Let’s have a game. Find a partner and arrange the jumbled word. Base your answer to the given definition and write it in a 1/4 sheet of paper. 3. 1. (Students will do the activity by two) 2. D. Discussing new concepts and practicing new skills #1. Answer key: 1. Convection 2. Conduction 3. Radiation EXPLAIN: Based on the game we’ve done, what do you think is our topic for today? Heat transfer ma’am. Very good. We are going to learn about heat transfer. Let’s watch the video. After watching the video, answer the questions. Conduction -Convection- Radiation-Heat Transfer.mp4 Questions: 1. ________ is the transfer of energy from objects of different temperatures. 2. _________ measure the kinetic energy. 3. As the temperature increases, the energy ________. 4. ______ is a process in which the transfer of heat takes place between objects by direct contact. 5. _______ is the heat transfer by movement of a fluid. 6. _______ is when heat transmitted without any physical contact. 7. Burning paper is an example of _______. 8. -10. Give the 3 methods of heat transfer. A. Developing mastery. (Formative Assessment) Answer key: 1. Heat 2. Temperature 3. Increases 4. Conduction 5. Convection 6. Radiation 7. Convection 8. Conduction 9. Convection 10. Radiation For us to better understand the concept of heat transfer, we will have an activity. Instructions: 1. Go to your group area. 2. Perform the activity and answer the following questions. Procedure: 1. Fill the cup with hot water. 2. Put the two spoons (Metal and Plastic) into the mug. 3. Arrange the spoons properly. Their handle should not touch one another. 4. After five minutes feel the handle of each spoon. Try to observe which spoon still feels hot and which spoon already feels cold. Directions: Answer the following questions based from the given activity you performed. Write your answer on a 1/4 sheet of paper. 1. Compare the two spoons, then determine which of them becomes hot first? 2. What type of object/s felt warm? 3. Which spoon is hot even though the handle is not submerged in the boiled water? 4. How do you differentiate a conducting materials from non- conducting materials? B. Finding practical applications of concepts and skills in daily living. Answer key: 1. The metal spoon. 2. Metal objects 3. Metal spoon 4. Conducting materials are low resistivity materials, which conduct heat as well as electricity while non- conducting materials are those can’t conduct electricity. ELABORATE: Let’s have an activity called FIXED ME. Instructions: 1. Stay in your group and arrange the (Student will perform and jumbled word. observe the activity) 2. Give example of the word. (Example: Heat is the word and example of heat is sun.) C. Making generalizations and abstractions about the lesson. To sum up our lesson, what is heat? Very good. There are three methods of heat Conduction, convection and transfer, what are they? radiation ma’am. Correct. What is the difference of conduction Conduction is a process in to convection? which the transfer of heat takes place between objects by direct contact while convection is the heat transfer by movement of a fluid ma’am. Very good. Radiation is when heat transmitted without any physical contact. Do Yes ma’am. you get it class? D. Evaluating learning. EVALUATE: Bring out 1/4 sheet of paper and let’s have a quiz. Directions: Write FACT if the statement is TRUE and BLUFF if the statement is FALSE. 1. There are four methods of heat transfer. 2. Conduction is a process in which the transfer of heat takes place between objects by direct contact. 3. Radiation is when heat transmitted without any physical contact. 4. Conduction is the heat transfer by movement of a fluid. 5. Heat is the transfer of energy from objects of different temperatures. Answer key: 1. BLUFF 2. FACT 3. FACT 4. BLUFF 5. FACT E. Additional activities for application or remediation. List down examples of conductive, convection and radiation materials. Prepared by: Checked by: JAMAIKA B.
