III. Procedures TEACHER’S ACTIVITY
STUDENT’S ACTIVITY
A. Review Class, what is our topic last meeting? Household and Personal Care Products Very Good! So Class, what is Surfactants? Surfactants is an active agent, capable of reducing the surface of liquids. For example, in washing oil plates. Very Good! How about the active ingredients of some antibacterial soap, example safeguard? Triclocarban Excellent! B. Motivation Class, I have pictures have. What do you see? There is a sequence of the motion/movement of the sky. Very Good! So, class, what is the motion of the sun and the stars on the picture? There is shifting from one place to another which is happen within 24 hrs. Excellent! C. Lesson Proper a. Activity Class, we have our group activity today. Each group have 2 to 3 members. Yesterday I have assigned each group to research and report on their chosen Greek Philosopher with its lifetime period and contribution. All of you boys and girls will participants on the class to give questions to the reporters. And the
reporters should answer the questions from their classmates. Class, listen to the reporter, participate, and don’t be noisy especially when the reporters perform their activity. (The students perform their activity) b.
Analysis Class, in our activity based on the report. Give example of one Greek philosopher, lifetime period and their contribution. (The student give one example of Greek philosopher, lifetime period and their contribution.)
c.
Abstraction Class, there are two – domain view of the of the Universe: The celestial and terrestrial domain. The celestial domain is perfect hence can only be made up of the perfect substance they called “either” and can only move on perfect motion: circular in path and constant in speed. While the terrestrial domain, object is imperfect and that the tendency of thing to attain perfection is the cause of their motion. They also believed that things, depending on their composition of the elements – fire, air, water, and Earth – tend to move toward the center of the Universe. Class, what are the differences between the two – domains view of the Universe? Celestial domain is perfect hence can only be made up or the perfect substance they called “either” and can only move in perfect motion while terrestrial domain, object is imperfect motion and they also believed that things, depending on their composition of the elements – fire, air, water, and Earth – tend to move toward the center of the Universe. Very Good! Class, if we look on the motion of the sky, there is a shifting of celestial objects. And there are two m otion based on time that can prove that the Earth is round. Diurnal motion of the sky is the appearance that the objects in the sky moves relative to the Earth’s local horizon (moon, sun, stars, and planets) as observed for one whole day at the same location on Earth. Annual motion of the sky is the appearance that objects in the sky moves relative to the background stars as observed at the same time of the day and the same location on Earth. Class, if we took pictures of the sky for 24 hours, what will you observe? What is that motion as we observed for one whole day at the same location?
Diurnal motion of the sky in which we observe within 24 hours. The naked eye observation also that the moon, sun, stars and planets are moves relative to the Earth’s local horizon for one whole day. Class, there are some following Greek philosophers shows their contribution about Physics and Astronomy, and one of that is Phythagoras (C570 – c. 495 BC). According to him, mathematics as the best way to express truth about the Universe, Sun, Moon and Earth one spherical. Plato (C427 – C347 BC), celestial spheres being crystalline and contains the moon, the sun and the stars. Aristotle (384 – 322 BC), two domain system with terrestrial domain containing 4 elements that tries to attain perfection by being natural location relative to the center of the universe, the center of the Earth. Thales (624 – 547 BC Ionian) believed that the Earth is a disk floating on an endless ocean. Class, who is the Greek philosopher believed mathematics is the best way to express truth about the universe?
Pythagoras.
Very Good! d.
Application Class, have you observed the star’s position at night? Yes, Sir. So what have you observed when we look on the stars in specific time and specific location; after one to more hours, what will happen on the star’s location? There is shifting on the star’s location. Very good! Another class, have you observed the sunrise and sunset here in San Jorge? Yes, Sir. Based on your observation, is it a proof that the Earth is round? Why? Yes, Sir because the sun and the stars shift from one location to another. Excellent.
IV. Evaluation I. Matching type choose the correct letter of the correct answer. 1. Celestial spheres being crystalline and contains the moon, the sun, and the stars. 2. Earth is a disk floating on an endless ocean. 3. Naked eye observation within one whole day on motion of the sky. 4. Mathematics as the best way to express truth about the Universe. 5. Naked eye observation of the motion of the sky over a period of one year.

ESSAY (5pts) 1. Differentiate the two domain view of the Universe? Answer. Celestial domain is perfect hence can only be made up of the perfect substance they called “either” and can only move in perfect motion while terrestrial domain, object are imperfect and that the tendency of thing to attain perfection is the cause of their motion.
