Materials: projector, laptop, speaker, activity sheets, printed pictures, marker and cartolina Procedure Teacher’s Activity A. Preparatory Activity Prayer Okay class, stand up. Aldred, please lead the prayer. Students’ Activity Okay classmates, are you ready to pray. Our Father who art in heaven, hallowed be thy name. Thy kingdom come. Thy will be done, on earth as it is in heaven. Give us this day our daily bread; and forgive us our trespasses, as we forgive those who trespass against us; and lead us not into temptation, but deliver us from evil. Greetings Good morning students! Please take your seats. Good morning teacher. Checking of Attendance Students, who is absent today? No one is absent today that’s good! No one is absent today, teacher. B. Review Before we proceed to our new lesson, let us first have a recap. What is our lesson yesterday? What is it about? Our topic yesterday is about _____________________. C. Motivation Let’s group you into two groups. The first group will be staying here and the other will be in the other side. Think of your group name. Who wants to play a game? Now, let’s play ANATOMY! Teacher, us! Here are the mechanics: Construct other words from the given word in just one minute. The group who can list the most number of words will receive chips. Are you ready to play? First word: EARTH One minute, starts now! Time’s up! Yes we are! Heart, ear, the, hear, tar Second word: ROTATION One minute, starts now! Time’s up! Rot, ton, tan, tin, rat, not, nor Third word: REVOLUTION One minute, starts now! Time’s up! Evolution, lotion, rot, not, nut, nor, over, ton, tin, D. Engagement The words that were displayed earlier have something to do with our new lesson. It is about the Earth’s Rotation and Revolution. But before we proceed to our discussion. Let’s have an activity. This activity is entitled “You Spin My Whole WORLD Around” The mechanics are: One representative to pick your task. Each group will demonstrate the given task to you. All the members should participate. After you perform you will receive chips. Task no.1 Demonstrate the rotation of the earth. Make sure that everybody will have their part. Be creative. Task no.2 Demonstrate the revolution of the earth around the sun. Make sure that everybody will have their part. Be creative. You have four minutes to talk about your task. The student will perform the task. Okay, group one, present your work. Okay, present your work group two. Very good, class. E. Exploration This next activity is “Creating Your Whole NEW WORLD” I will give your team envelope; there are instruction and materials inside. This activity need to be done after five minutes. The student will make their own model. Your time starts now! Time’s up! The student will listen carefully to the F. Explanation You see the sun sets right? And if you discussion. get up early enough maybe you see the sun rise too. But have you ever wondered if the sun sets and rise every day, where does it go when we can’t see it? Well nowhere, it is actually us who goes somewhere. Because we are on earth and earth is always turning or spinning on its axis. Earth has an invisible line which we called the axis. Axis is an invisible line around which an object rotates or spins. Earth spins around on its axis like a top. This movement is called rotation. Earth’s rotation gives us day and night. If you are located on the side facing the sun it is day and when on the other side obviously its night. Actually earth is moving more ways than one. At the same time the earth rotating on its axis, it also orbits the sun. This movement is what we called revolution. One full orbit around the sun is one revolution and earth takes 365 days or one year to complete a one revolution. As the earth is both revolving and rotating it is not sitting straight up, it is actually tilted over 23.5 degree. And it cause the one side of the earth tilted over the sun while the other is leaning away. It only means that different parts of the earth gets different amount of sunlight. The earth creates pattern as it travels around the sun. This pattern created seasons. If the part of world you living in is leaning over the sun it is summer while the part that is leaning away it is winter. And in between those are autumn and spring. If the world is not tilted we will always have the same season over and over again. G. Elaboration ROTATION VS. REVOLUTION is the last activity we have. Fill out the table with the correct response. The students will fill out the table given by the teacher. H. Evaluation 1. Differentiate the revolution and rotation. (5 points) 2. Explain the pictograph below. (5 points) IV. Assignment Answer the following question. 1. Days and night are caused by o The tilt of the Earth’s axis o Earth’s revolution around the sun o Earth’s rotation on its axis 2. Earth’s rotation takes about o 365 days o 6 months o 24 hours 3. One complete revolution of earth around the sun takes about o One rotation o One year o One eclipses 4. Earth has seasons because o Earth rotates on its axis o Earth’s axis is tilted as it moves around the sun o The temperature of the sun changes 5. It is the star that provide us light and heat o Sun o Moon o Earth Republic of the Philippines Laguna State Polytechnic University Province of Laguna College of Teacher Education Center of Development Earth’s Rotation and Revolution Prepared by: Dareen Cueto Date: February 11, 2019
