Page ` Republic of the Philippines NUEVA ECIJA UNIVERSITY OF SCIENCE AND TECHNOLOGY Cabanatuan City, Nueva Ecija, Philippines COLLEGE OF EDUCATION m-m-e-r-s-u Very good! The last word is summer. Ma’am, it is summer. Give yourself five magical claps. (The students will clap five times.) D. Presentation of the lesson Based on the game that we played, what do you think will be our lesson for today? I think, our lesson for today is about the rotation and revolution of the Earth. Very Good! It is all about the two motions of the earth, which is the rotation and revolution of the Earth. If the Earth is not revolving around the sun, how do you imagine the world to be? Ma’am, I think it would be hard to live on our planet. Right! It would be hard to live on our planet or worst, the lives of living things might not become possible if that happens. How do I say so? Let us watch the video entitled the Rotation and Revolution of Earth - Movements of the Earth Earth's Revolution & Rotation to find out the answer. (The teacher will present the video entitled “Rotation and Revolution of Earth - Movements of the Earth - Earth's Revolution & Rotation” https://www.youtube.com/watch?v=CqkQv617bcw) E. Lesson Proper Children, what is the video all about? Yes, Ma’am. (The students will watch the video and taking a note at the same time.) The video is all about the motion of the earth. Is the earth moving? Yes, the earth is moving. How does it move? It moves in two ways; it spins in itself and it spins around the sun. 3 While watching the video, take some notes because I will ask you questions about it. Is that clear? Page ` Republic of the Philippines NUEVA ECIJA UNIVERSITY OF SCIENCE AND TECHNOLOGY Cabanatuan City, Nueva Ecija, Philippines COLLEGE OF EDUCATION What is rotation? Rotation is when the earth spins on its axis. How about the revolution? Revolution is when the earth rotates around the sun. Very good! (The teacher will present the lesson with the use of a PowerPoint Presentation and some objects.) Earth has two types of motions namely, rotation and revolution. Rotation is the movement of the earth on its axis. Imagine a line passing through its center of mass, this imaginary line is called the axis. Did you ever see top spinning? Yes, Ma’am! I play it. Our planet spins around on this invisible line just like a top. The circular movement of an object spinning around on its axis is called “the rotation”. Due to this rotational quality of the earth, we witness day and night. The earth receives light from the sun, due to the spherical shape of the earth only half of it gets light from the sun at a time. The portion facing the sun experiencing the day, while the other half away from the sun experiences night. That is right, the other side of the world is having night. When we have night, they are having a day. The other side of the world is experiencing night. 4 What is happening on the other side of the world when we have a day? Page ` Republic of the Philippines NUEVA ECIJA UNIVERSITY OF SCIENCE AND TECHNOLOGY Cabanatuan City, Nueva Ecija, Philippines COLLEGE OF EDUCATION The earth takes about 24 hours to complete one rotation around its axis to make a single day. If the rotation of the earth makes a day, then what makes a year? The revolution of the earth makes a year. Yes, it is the revolution. You see, although the earth is rotating on its axis, at the same time, it also revolves in orbits around the sun which is called revolution. The earth is always moving around the sun. The sun is the center of the solar system. Where the earth and all other planets orbited, we called this a fixed orbit, it always stays the same. And one full orbit around the sun is one revolution. The earth takes about 365 days and 6 hours to complete a revolution that makes up a whole year. There is more to learn about the earth’s rotation and revolution. We say that the earth rotates on its axis, the axis is an imaginary line that goes through the middle of the earth. It helps us to understand how the earth spins. The axis is not straight up and down. The earth tilts a little as it spins, this tilting is very important. It is the reason we have seasons. At a particular time, the northern hemisphere is leaning towards the sun while the southern is leaning away. And at other times, the southern hemisphere tilts toward the sun, whereas the northern hemisphere leans away. And this is why we have different seasons and why the seasons are 5 Due to this angle, the solar energy reaching every part of our planet is not constant but varies during the year. Page ` Republic of the Philippines NUEVA ECIJA UNIVERSITY OF SCIENCE AND TECHNOLOGY Cabanatuan City, Nueva Ecija, Philippines COLLEGE OF EDUCATION opposite in the Northern and Southern Hemispheres. What do you think is the season on the part of the earth that leaning towards the sun? The part of the earth that is leaning towards the sun is having a summer. How about the other part that is leaning away from the sun? That part is experiencing the cold season. Yes, very good! The part of the earth leaning towards the sun causes summer in that region and the days are long. While the part leaning away experiencing cold climate with shorter days. F. Application Children, I have here flashcards with different text or image that talks about the rotation or revolution of the earth. All you need to do is to identify if the flashcard is referring to rotation or revolution. (The students will listen to the instruction attentively.) If it refers to rotation, close your right arm and rotate it, like this (the teacher will demonstrate how to do it). Do you understand? Yes, Ma’am, (The teacher will show the flashcards and let students answer.) (The students will actively participate in the activity.) 6 However, if it refers to revolution, you are going to close your two hands while the left hand will still in the middle and the other hand will revolve around it, just like this (the teacher will demonstrate how to do it).

Revolution (The students will close their two hands while the left hand will still in the middle and the other hand will revolve around it.) Revolution (The students will close their two hands while the left hand will still in the middle and the other hand will revolve around it.) 7 Rotation (The students will close their right arm and rotate it.)

Revolution (The students will close their two hands while the left hand will still in the middle and the other hand will revolve around it.) Rotation (The students will close their right arm and rotate it.) 8 Revolution (The students will close their two hands while the left hand will still in the middle and the other hand will revolve around it.) Page ` Republic of the Philippines NUEVA ECIJA UNIVERSITY OF SCIENCE AND TECHNOLOGY Cabanatuan City, Nueva Ecija, Philippines COLLEGE OF EDUCATION G. Generalization What are the two (2) motions of the earth? (Children will do the yahoo clap.) The rotation and revolution are the two motions of the earth. What is the difference between rotation and revolution? Rotation refers to the spinning motion of the earth its axis. However, revolution refers to the earth’s orbital motion around the sun. The rotation has a shorter time to complete while the revolution takes a longer time. How long does it take one complete rotation of the earth? One rotation of the earth takes 24 hours or simply a day to complete. What are the effects of rotation? Due to the rotation of the earth, we are experiencing daytime and nighttime. How long will it take to complete one revolution? One revolution takes 365 days or simply a year to complete. What are the effects of revolution? Due to the revolution, we are experiencing seasons. Why do we have seasons? The distance between the earth and the sun changes due to revolution. This change of distance also causes a change in seasons. What will happen if the earth stops rotating? The portion of the earth facing the sun would always experience day, thus bringing continuous warmth to the region. The other half would remain in darkness and be cold all the time. Life would not have been possible in such extreme conditions. 9 Very good! Children, give yourselves a yahoo clap. Page ` Republic of the Philippines NUEVA ECIJA UNIVERSITY OF SCIENCE AND TECHNOLOGY ` Cabanatuan City, Nueva Ecija, Philippines COLLEGE OF EDUCATION What is the importance of the two motions of the earth? As the Earth rotates and revolves, each area of its surface gets a turn to face and be warmed by the sun. That is important because sunlight gives us life. Very Good! Give yourself an “Ang galing clap”. (The students will do the “Ang galing clap”.) IV.
