I. OBJECTIVES At the end of the lesson, the students should be able to: a. describe the transformations of energy; b. construct a flow map about energy transformations; and c. cite an example that shows transformation of energy. II. CONTENT a. Topic: ENERGY TRANSFORMATIONS b. Learning References: Grade 9 Science: Teacher’s Guide, pp. 192-193 Grade 9 Science: Learner’s Material, pp. 281-284 c. Materials: Visual Aids, PowerPoint presentation, Projector, Manila paper, and Pentelpen.

PREPARATION a. Greetings b. Cleanliness Check c. Attendance Check

a. Elicit Ask students the following question: Have you experience being grounded in an electric wire? Have you seen an airplane flying with full of military bombs? How about ringing fire alarm while there is a fire? To answer the questions, we must have sufficient idea about energy transformations. b. Engage Recall: To test student’s background knowledge, allow them to determine the different types of energy presents in the slides. 1. Ask students what energy is presented in the picture. 2. Let other students participate by asking if it is correct. Motivation:

Do the game “4 pics 1 word”. Show pictures and ask students the appropriate word for it. Try it also with another picture then ask students to combine those 2 words formed. The answer should be “ENERGY TRANSFORMATION”.

Student Activity

Call one student and ask what is energy Student will define energy transformations based transformations? on his understanding. Allow students to watch the video about energy transformation. Explain the definition of energy transformations Students will have an idea regarding energy and give examples of it. transformations because of the example. (Group Activity) Time allotted: 20 mins (5 groups) What to do: “Construct a flow map showing the flow Students will go to their designated group. of energy transformations based on the pictures taken”. Students will participate in the group activity and Let students illustrate the pictures with an arrow collaborate ideas to each other. for the flow of energy transformations. A volunteer student will present the output. d. Explain Discuss the main topic: 

According to Law of Conservation of Let students give examples of energy that Energy, energy is neither created nor transfer into different forms of energy. destroyed but it can transform into different forms of energy.



Discuss that in every energy transfer, Students shall relate that every object has a there is an input then transformation working mechanisms of energy transformations and conservation. process and output.



Give examples of energy transformations taking place in Electrical energy.



Engage students to recite for the following energy transformations Students will recite the correct energy transformations from input to output. examples.

e. Elaborate Expand the discussion transformations by:

about

a. Asking students to cite an example Students will recite examples of transformations that shows transformations of of energy taking place in everyday living. energy. f. Evaluation Directions: Choose the letter of the correct answer. 1. The law of conservation states: ________ a. Energy can be created and destroyed b. Energy is never created nor destroyed. c. What goes up must come down. d. Electrical energy can be transformed into other forms. 2. When a turbine rotates to produce electricity, what energy transformation takes place? a. Thermal -> mechanical b. Electrical -> electromagnetic c. Chemical -> electrical d. Mechanical -> electrical 3. Which of the following kinds of energy is not involved in the energy transformations in battery powered flashlight? a. chemical b. light c. heat d. sound 4. In an incandescent light bulb, it can transform electrical energy into ______. a. sound energy b. light energy c. light and heat energy d. heat energy 5. During energy transformations, energy is never __________. a. Released as heat b. Used to increase an object's potential energy c. Created or destroyed d. Completely transformed. V.
