TEACHING PROCEDURE Teacher’s Activity Student’s Activity A. PRELIMINARIES - Greetings Good afternoon, Ma’am/ Sir! Good afternoon, everyone! It is another good day to learn. So, before we start our discussion for a new lesson, remain standing for our opening prayer. Angel of God My guardian dear To whom God’s love Commits me here. Ever this day Be at my side, To light and guard. To rule and guide, Amen. - Organizing the classroom setting Before we seat, kindly pick up any pieces of paper or trash under your chair. Align your chair properly and you may sit down. - Checking of Attendance Look at your seatmates, is there any absentees? None. B. REVIEW “Before going to the new lesson, let us have a review about what we discussed last meeting. “Anyone, who remember the topic we have discussed?” “Who can define the meaning of “Sir, it’s all about energy.” energy?” “Sir, energy is the ability to do work” C. ENGAGEMENT “Let’s play a game. I have prepare a game for today’s lesson. This game called “Jumbled Letters”, all you need to do is to guess the words and arrange the jumbled letters to its corresponding word. So, let’s start. (The teacher paste the jumbled letters on the board and the students will guess it.) ULBB ABTRTYE TIWCHS (Students guessing what the word is.) UNCODINGT IREW BULB BATTERY Very Good Everyone, you guess SWITCH CONDUCTING WIRE the words right. D. EXPLORATION The class will watch a video that tackles about “How the bulb light up and how people used electricity and how it works” After watching the class will divided into two groups and will answer the following question: (Bulb light up) 1. What are the materials that needed to make a bulb light up? 2. What if there is no battery do you think bulb will light up? 3. What is the used of battery, wire and switch? 4. How often do you used the light bulb or any electrical appliances in your home? Do you used it wisely? 5. Draw illustration on how the bulb light up? (Electricity) 1. Does the people used the electricity wisely? Why? 2. How would you used the electricity? 3. How electrical appliances works? E. EXPLANATION “Class, are you done?” Okay group 1 present you work in the front. Alright, let’s give group 1 a round of applause. Yes, teacher. (Group 1 will present their work in the front) Let’s proceed to the next group. Group 2 please in the front and present your work. Let’s give group 2 a round of applause. F. ELABORATION Circuit is the complete loop through which an electrical current flows. The word “circuit” comes from the Latin word circuitous which means “go around”. It is made up of a series of electrical components and conductors. A circuit always needs a power source, such as a battery, with wires connected to both the positive (+) and negative (-) ends. A battery is also known as a cell. A circuit can also contain other electrical components, such as bulbs, buzzers or motors, which allow electricity to pass through. The parts of Electric Circuit 1.) Bulb –it is an object that uses electrical power or electrical energy. (Group 2 will present their work) 2.) Battery- it is the source of energy or electricity. 3.) Conducting wire- it is a cable or link that connects the source of energy to the bulb. A safety device that is put in a circuit to connect the parts of the circuit 4.) Switch-it is controlling device which is used to open or close a circuit. When there is a break or gap in an electric circuit which disallow the flow of current through the circuit is known as open circuit. In an open circuit, no current can flow from the source to the load due to incomplete path between the energy source and the load. Therefore, the open circuit represents the circuit in OFF state. The open circuit may be due to switch in OFF state or failure of any component in the circuit. An electric circuit is said to be closed if there is continuous path from the energy source to the load. Thus, an electric circuit which has a closed loop path to flow of current from source to load is called a closed circuit. The closed circuit represents the ON state of the circuit. The main parts of a closed circuit are: a conducting wire, source of energy (ex. battery) and an electric load. These components joined together to form a closed loop so that current can flow from source to load through wire. APPLICATION The class will divided into two groups, both group will do a simple circuit. The teacher will give the materials for them to do a circuit. After doing the activity the each group will present their work in the front. What is the materials need in lighting the bulb? Explain each their function. (Each group will present their work) GENERALIZATION What you’ve learned for today’s discussion? What is needed to make a simple circuit? (We learned how to light up the bulb) (We a bulb, wire, battery and switches) How do you define them? Bulb –it is an object that uses electrical power or electrical energy. Battery- it is the source of energy or electricity. Conducting wire- it is a cable or link that connects the source of energy to the bulb. A safety device that is put in a circuit to connect the parts of the circuit. Switch-it is controlling device which is used to open or close a circuit. G.
