Review the pupils in the previous lessons learned. 2. Ask: What are the different Public Storm Warning Signal (PSWS). What are the effects of typhoon to living things and the environment. 3. Ask the pupils: How many moons the earth has? Present a picture of moon and let the pupils describe it. Present also pictures of moon with different shapes. Ask the pupils to give their interferences on why the moon changes its appearance from time to time. B. Exploration Say: I will group you into three. Let them do the same activity Assign activity for each group. MOON MODEL Science Skills: Observing, Communicating Time Frame: 20 minutes You Will Need: Globe Flashlight Small ball What to Do: 1. Place the globe at the center of the table. 2. Turn off the lights in the room. Make sure that the room is dark enough so as to enhance the light coming from the flashlight. 3. Turn on the flashlight. Be sure to focus its light on the globe. 4. Hold the small ball in between the globe and the flashlight. 5. Turn the ball slowly around the globe. DO NOT MOVE THE FLASHLIGHT. 6. Observe what portion of the ball reflects light. Does the ball change its shape? Please explain. Questions: 1. Observe what portion of the ball reflects the light. Does it change its shape? Please explain. 2. On a piece of paper, draw the lighted portion of the ball in the different positions. Earth/Globe 3. Compare your drawing with your classmates. C. Explanation Let each group report on activities, and answer the guide questions on their science book. Let the pupils explain. Why moon changes each appearance from time to time? (It because the illuminated portion on the moon changes as it moves around the earth. This apparent change on the appearance of the moon is known as the phases of the moon.) Does the ball change its shapes? Please Explain. (The image of the moon does not look the same the whole month. Sometimes it is a full circle sometimes you see only half of it, and sometimes appears as crescent.) Why do you think its happen? (Because when the moon is between the appearance of the quarter moon and new moon the moon is called crescent. D. Extension/Elaboration 1. What are the four phases of the moon? 2. How many weeks for a moon to change from one phase to another? 3. What are the four main phases of the moon? 4. How many days does it take for the moon to complete one phase? BACKGROUND INFORMATION FOR TEACHERS The moon is the only satellite that Earth has. A satellite is an object that revolves around a larger object. The moon does not produce its own light. It only reflects the light coming from the sun. Since the moon is revolving around the Earth the amount of light if reflects from the sun varies as it changes its position. Phases of the Moon The moon has four phases. These are the new, first quarter, full moon, and the last quarter moon. It takes about one week for a moon to change from one phases to another. When the moon is between the sun and Earth, you cannot see the moon; it is called new moon. During this phase, the moon is not visible from the earth. This is because the side of the moon that is facing us is not being lit by the sun. About a week after the new moon, you see half of the lighted side of the moon. This is called the first quarter moon. A week after the first quarter moon, you can see the whole lighted side of the moon. This is called the full moon. A full moon appears as an entire circle in the sky. On the third week of the month, you again see half of the moon’s lighted part. This is called last quarter moon. Soon the moon disappears again; another new moon appears. When the moon is in between quarter moon and the full moon, the moon is called gibbous. Gibbous moon is more than half-lit. The moon goes through these eight phases in 29 ½ days. The period it takes the moon to complete is called month. Waxing Phases of the Moon After a new moon, when the moon seems to be growing, it is undergoing a waxing phase. As the moon starts to appears in a semicircular form, waxing crescent starts to appear. During the first quarter, half of the moon is lighted and visible. When most of the portion of the moon is visible in the sky, it is known as waxing gibbous. Then, the whole lighted side of the moon that is visible from Earth is known as the full moon. As full moon appears as an entire circle in the sky. Waning Phases of the Moon After full moon, the waning phase of the moon starts. It is when the moon appears to be getting smaller each night. Waning gibbous appears after a full moon. Most of the portion of the moon is visible in the sky but, this time, it gets smaller every night. Then, the last quarter will be seen followed by a waning crescent. E. Evaluation: A. Match the items in Column A with the items in Column B. You may write the letter of the correct answer on a separate sheet of paper. Column A Column B _________1. The phase seen when the moon is between the Sun and Earth a. month _________2.
