B. HOW WILL THE LEARNING PROMOTE 3. ETHICAL FORMATION: Reflects how disaster preparedness can save life. 4. SOCIAL RESPPONSIVENESS: Promotes safety and disaster-risk reduction. II. ESSENTIAL QUESTION How do the structure and composition of the earth cause geologic activities and physical changes? III. MATERIALS, METHODS, AND ACTIVITIES MATERIALS METHOD Video: Crust, Mantle, Cores Song ICT-based Teaching https://www.youtube.com/watch?v=plNigVkMyL8 Differentiated Instruction Activity Sheets Direct teaching collaborative ACTIVITIES Song Presentation Small grouped discussion IV. Procedure: Teacher’s Activity A. Motivation: Good morning class! Student’s Activity Good morning ma’am! How are you today? That’s good! Were fine and doing great ma’am. Have you ever wonder what is inside the earth? Yes ma’am! We wonder, when we dig it it’s made of soil and rocks, but when a volcano erupted; magma comes out and became lava. Yes it is! So, what do you imagine about earth’s interior? To check whether your answer is correct, go to your group and form a circle. It is made of solid and liquid ma’am. (Students go to their group and form a circle) B. Presentation Let us watch and listen to the song I prepared. Listen carefully because I will give you 5 minutes to practice and then afterwards you’re going to perform here in front. Do you understand? Yes ma’am! (A video clip will be played) It’s a nice song right? Yes ma’am! Now I will give you 5 minutes to practice the song and then each group will perform here in front. You will be scored with the following criteria; presentation, musicality, content, organization and originality. (after 5 minutes) Group 1 will be the first to perform then 2, 3, and 4. You will be scored based from the rubrics. (See attached rubrics at the back). (Group Performance) (After all groups are done performing says); Well done! Each group done their best and I’m very glad that you performed well. Thank you ma’am! Based from the lyrics of the song, do activity 1 entitled “I know”. (see attached activity) (the teacher will give the activity sheets to the students) You will be given 5 minutes to finish the activity. You are going to complete the sentence based from the lyrics of the song. Any question? None ma’am. You can start. (After 5 minutes) Time’s up! Let us discuss what you have written on the activity sheet. Who will read what she/he writes on its paper? Yes Joanna. (students raise their hands) I know that I know something about the layers of the Earth. First, is the outer part of the Earth which is the crust and it ranges from 5 to 40 km. The crust is also made of rock and soil. In addition, below the crust is the mantle where convection is going on. Finally, the outer in inner core where it is like a wave of metal mush of nickel iron and liquid gel while the inner core is holding on atoms and it is solid. Now you know something that I know about the layers of the Earth. Very Good! Gwyneth can you read what you have written on your paper? Very Good! Who wants to share also his /her answer on the activity? I know that I know something about the layer of the earth. It is made up of rock and soil and ranges from 5 to 40 km. in addition, mantle is below the crust where lithosphere and asthenosphere is located and convection is going on. Finally, the core where it is divided into two, the outer core and inner core. The outer core is made of liquid gel while the inner core is solid. Now you know something that I know about the layers of the Earth. (Many of the students raise their hand. And some of them called and share their answers.) Very good! Based from the song there are different layers of the Earth. Now you have an idea about the layers of the Earth let us have another group activity. Bring out your manila paper. I have here a puzzle, so you’re going to form the pieces of puzzle. Label and list words that are associated with the formed cross-sectional illustrations of the layers of the Earth. You are given 5 minutes to finish the activity then one of the members of the group will present their work in the front. Do you follow? Yes ma’am! Yes Ma’am! May I request one member of the group to get an envelope on top of my table, inside the envelope are the pieces of puzzle. (representative of the group draw their envelope) Ready? Yes ma’ am! Then you can start. (After 5 minutes say) Times up. Group 1 will present first their work, followed by group 4, then group 3 and finally the group 2. Do you understand? Yes ma’am! Group 1: Based from the lyrics of the song there are 4 layers of the atmosphere, the crust which consist of the continental crust and oceanic crust. The crust is made up of soil and rocks and it ranges from 5 to 40 km in length. Deep down the crust is the mantle where convection is doing his job. Asthenosphere and lithosphere is also located on this layer of the earth. Below the mantle is the outer core composed of metals like nickel, iron and liquid gel. And the innermost part of is the inner core that is like a solid ball. Excellent. Let us give them a round of applause. Let us give the floor to our next group. (Group 2 share their output) Excellent. Let us also give them a round of applause. (the procedure of presenting groups output were followed) Wow that was an excellent performance. With the use of the lyrics of the song you labelled the cross sectional layer of the Earth. So what have you learned from our activities for today? Very good! For your assignment bring marker pen and manila paper. Still practice with the song. We are going to use again the lyrics for our next activities. That all for today. Prepared by: MAYBELLE A. PAGUYO Science Teacher We have learned a lot from the different activities that we performed today. From the song we found that there are four layers of the earth and its layer has its own characteristics. Yes ma’ am! Goodbye and thank you ma’am.
