Reviewing previous lesson or presenting the new lesson (ELICIT) Prayer: “Good morning, Class...” “Let us pray first… kindly lead the prayer... Greetings: ” Okay, good morning class! Okay you may now take your seat! Attendance: So, who are absent for today? Classroom Rules: Please be guided with these gentle class rules: 1. Make sure you have everything you need before starting. 2. Everyone deserves respect both students and teachers. 3. Raise your hand to talk. 4. Show respect for school and personal property. 5. When someone else is talking, listen. 6. Do not talk when somebody is talking. Are all these rules clear? Okay, very good! I hope that you will follow all of these class rules. Review: “Ok, class, before we proceed to our new lesson. Let us have a short review with the lesson that we discussed last week. Good! So, what are the colors present in sunlight? -Good morning Sir! (One of the learners will raise his/her hand to lead the prayer.) -Thank you Sir! -(Somebody will announce the names of the learners who are not around) -Yes Sir! -Our topic last week is about characteristics of light Sir! Objective 5 Safety policies and procedures (Establish safe and secure learning environment to enhance learning through the consistent implementation of policies, guidelines and procedures)
- 3. Yes, Johannah Feb! Very good! Last week we have discussed about Light and its characteristics. Motivation: Now, let us have an activity. And this activity is titled “Guess the Sound”. What you are going to do is listen to the sound and guess the object that makes the sound. You have choices to choose from. Are you ready? What’s the answer in number 1? Very good! Number2? Very Good! …. (The allotted time for this activity is 5 minutes) Base on our activity, what do you think will be our topic for today? Can you guess it? Good! Our topic for today is about “Characteristics of Sound” -Red, Orange, Yellow, Green, Blue, Indigo, and Violet Sir! -Yes Sir! -Letter A Sir! -Vacuum cleaner Sir -Possible answers: -Sound -Types of Sound -Characteristics of sound. Objective 2 Used a range of teaching strategies that enhance learner achievement in literacy and numeracy skills. B. Establishing a purpose for the lesson Reading of lesson objectives: Objectives: a. define sound b. appreciate sounds within their surroundings. c. apply the properties of sound using different materials for an emergency situation.
- 4. C. Presenting examples/instance of new lesson (ENGAGE) Unlocking of difficult words: Amplitude - the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. Wavelength - the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire. Velocity - a vector expression of the displacement that an object or particle undergoes with respect to time. Pitch - refers to highness and lowness of sound. Loudness - how soft or how intense the sound is as perceived by the ear and interpreted by the brain. Sound is more distinct in solids than in any other medium. It is louder than that of in liquid and in gas. It is because the particles of a solid are more compact than that of liquid and gas. This allows for sound to travels fastest in solid and slowest in gas. The table shows the speed of sound in different media: Materials Speed of Sound v(m/s) 1.Air (0o C) 331 2.He (0o C) 1005 3. H (0o C) 1300 4. Water 1440 5.Seawater 1560

The frequency is related to the pitch of a sound which is defined as the perception of highness or lowness. The faster the sound waves move, the greater the frequency and the higher the pitch. The hertz (Hz) is a unit to measure frequency and so pitch is measured in hertz. Another characteristic of wave which is related to the pitch of a sound wave is the wavelength. The minimum distance in which a sound wave repeats itself is called its wavelength. 2. Loudness and Amplitude (A) The amount of energy a sound wave carries is known as intensity of the sound. Loudness is a psychological sensation that differs for different people and it is related to the intensity of sound. So, the loudness of a sound is determined mainly by the amplitude of the sound wave. Sound cannot travel in a vacuum. Remember that sound is a mechanical wave
- 6. D. Discussing new concepts and practicing new skills #1 (EXPLORE) Group Activity: MAKE YOUR SOUND! Instructions: The class will be grouped into 3, you will create your own sound out of the materials inside the classroom. (Clapping and the use of voice is allowed). They will be given 10 minutes to do the task. You will be rated through a rubric. I hope everyone will cooperate with your group so that you will have an impressive outcome and your task will be finished on time. Is it clear? Rubrics in Rating Group Tasks CREATIVITY (The kind of materials they used) - 5% ORGANIZATION (The clarity of sound) - 5% TEAMWORK - 5% TOTAL 15% Yes Sir! Objective 3 Applied a range of teaching strategies to develop critical and creative thinking, as well as other higher-order thinking skills. Objective 6 Maintained learning environments that promote fairness, respect and care to encourage learning. E. Discussing new concepts and practicing new skills #2 F. Developing mastery (Leads to formative assessment) (EXPLAIN) 1. In your activity, you have observed that sound is produced by singing, clapping, using lyre, or drum. The vibrations created by clapping or singing produced the sound. This also shows that? 2. Sound is more distinct and louder when in what medium? Why Sound can be heard /travels through different sources / media. In solid. It is because the particles of a solid are more compact than that of liquid and gas. This allows for sound
- 7. 3. You have observed that each material you’ve used has different sound created. Sound has properties which are pitch and loudness. What do you think is the difference between this two? to travels fastest in solid and slowest in gas. Pitch refers to highness and lowness of sound. G. Finding practical applications of concepts and skills In this present time, environmental problems are one of the major disasters that affects our community. To inform everybody on the coming disaster, people created loud sounds from different things in order to produce sound with larger amplitude, longer wavelength and faster velocity. As a student, you must be prepared in order to make yourselves and others safe. What are those things or object that can be used as an early warning device considering a loud sound must be produced? Very Good! Objective 1 Applied knowledge of content within and across curriculum teaching areas. (Environmental Science/ DRRM) H. Making generalizations and abstractions about the lesson (ELABORATE) Now, who can give another importance of sound in our daily living? Very Good! Possible Anwer/s; Sound plays an essential role in our subsistence: it informs us of the nature, objects and actions. We communicate by using our ears to hear every sound.
- 8. I. Evaluating learning (EVALUATION) Direction: Arrange the following materials where sound can travel the slowest to the fastest, 1 as the slowest and 8 as the fastest. Air Helium Hydrogen Aluminum Hardwood Iron and Steel Water Seawater 1._________ 2.___________ 3.___________ 4.___________ 5.___________ 6.___________ 7.___________ 8.___________ J. Additional activities for application or remediation (EXTEND) Direction: Answer the following questions completely. Write your answer in the space provided. 1. Which would best transmit sound: steel, water, or gas? Why? 2. If you are in space, are you capable of listening to another spaceship approaching you? Why or why not? Is that clear? Any question or clarifications? I hope you learn a lot from this session. Yes Sir! None so far Sir!
- 9. Okay, so before we leave the classroom, kindly pick pieces of paper and arrange your chairs. Okay, class, that’s all for today, and Goodbye! Goodbye! And thank you Sir! V.
