The learners demonstrate an understanding of the formation of the universe and the solar system The learners shall be able to conduct a survey or design a study to assess the possible hydrometeorological hydrometeorological hazards that your community may experience. III. Learning Competencies The learners state the different hypotheses explainin explaining g the origin of the universe. S11/12ES-Ia-e-1 IV. Lesson Objectives  At the end of the lesson the learners learners must be able able to explain the Big Bang Theory Theory  At the end of the lesson the and evidences supporting the theory. learners must be able to differentiate Big Bang Theory and Steady State Theory V. Subject Matter Origin of the Universe (Big Bang Theory) Theories on the Origin of the Universe Vacant VI. Learning Resources You and the Natural World, Earth and Life Science text book (pg. 311) Exploring Life through Science Series (pg. 5-7)

VII. Procedures  A. Review previous lesson lesson or presenting a new lesson

How do creation myths explain the origin of the universe?

B. a purpose for On the board, the their theEstablishing lesson students will write insights about the Big Bang theory. C. Presenting examples/ The universe is instances of new lesson everything, from the tiniest particle up to the largest galaxies to the very existence of time, space and matter. Without the universe there will be no galaxies, without galaxies there will be no solar system,

What is a Big Bang Theory? What are the stages under the radiation era?

What are the stages under the matter era?

The teacher will present an infographic to the class containing the development of the universe.

One second after the Big bang, he universe was filled with neutrons, protons, electrons, antielectrons and photons.

What is meant by the word “red shift”? 

The students willwill form 4 quiz groups and they have bee.

*Cosmic microwave The pupils will bring out background radiation their balloons (representation (representati on for the entire universe) and will put dots as representation for galaxies and after that they will start inflating the balloon.

 

without the solar system there will be no planets, without planets, there will be no Earth, without Earth there will be no us. Roughly 380,000 years D. Discussing new concepts  According to the Big after the big bang, matter and practicing new skills Bang Theory the

E. Continuation of the discussion of new concept

F. Developing mastery (Leads to formative assessment)

universe started from a hot and intensely dense point only a few millimeters wide and was similar to a supercharged supercharged blackhole. There were two major stages of the universe's evolution called Radiation Era and Matter Era.

*Radiation Era 1. Planck Epoch 2. Grand Unification Epoch 3. Inflationary Epoch 4.Electroweak Epoch 5. Quark Epoch 6. Hadron Epoch 7. Lepton and Nuclear Epoch

*Why do we need to G. Finding practical applications of concepts and study our past? *What can we learn from skills in daily living them? H. Making generaliza generalizations tions and abstractions about the lesson

*How did the universe came to be? *What is it made of?

With the assistance of the teacher, the pupils will

cooled enough for atoms to form during the era of recombination, resulting in a transparent, electrically neutral gas.

observe what happened to the dots. *Are they expanding away from each other?

*Matter Era 1. Atomic Epoch -begins about 50,000 years after the big bang -atoms formed and remained intact -CMBR appears -ends 200,000,000 years after the big bang 2. Gallactic Epoch -large scale structure and bulk of most galaxies form -last from 200,000,000 to 3,000,000,000 years after big bang

The red shift of light gives scientists information on the speed and direction that a star is moving. This in turn tells scientists that stars are not only moving away from Earth, but they are also moving away from each other. The evidence that the universe is expanding comes with something called the red shift of light. Light travels to Earth from other galaxies. As the light

3. Stellar Epoch -stars continue to form up to today -extends into dark energy era.

from that galaxy gets closer to Earth, the distance between Earth and galaxy increases, which causes the wavelength of that light to get longer.

*How do scientists show their open-mindedness to changes? *Why should we also be open-minded? What are the stages under the Matter Era?

*What does red-shift mean? *What makes the Big Bang Theory the most widely

What makes steady state theory unacceptable? unacceptable?

 

I. Evaluating learning

*What are the stages under the Radiation Era? True/false: 1. The most acceptable theory about the beginning of the universe is the steady state theory.

J. Additional activities for application or remediation

accepted theory about the origin of the universe? Identification: 1. This is the earliest epoch in which matter and energy has existed in the universe.

How did the CMBR supported the Big Bang Theory? Short quiz: 1. 2-4: List down the 3 abundant elements in the universe. 5. CMBR stands for ________ 6. The universe is approximately ________ years old. 7. Who are the proponents of the CMBR? 8. Who are the proponents of the Steady State Theory? 9. Who proposed the big bang theory? 10.

2. In this epoch the universe cooled down enough for quarks to bind together to form proton and neutron. 3. This is when the universe rapidly expanded and instantly grew from a size of an atom to a size of a fruit. 4. This epoch is composed of 3 unified forces of nature called electroweak, gravity, and strong nuclear. 5. In this epoch the first ever chemical element of the universe is created. If you are to make your own hypothesis about how the universe began and formed, how would it be and why?

In a ½ sheet of yellow pad, using a Venn diagram, compare and contrast the difference between Steady State Theory and Big Bang Theory.

VIII. Remarks IX. Reflection  A. No. of learners who earned 70% on the formative assessment B. No. of learners who require additional activities for remediation C. Did No. the of remedial lesson work? learners who

 

have caught up with the lesson D. No. of learners who continue to require remediation E. Which of my teaching strategies worked well? Why did this work? F. What difficulties did I encounter which my  principal or supervisor supervisor can help me solve? G. What innovation or localized materials did I use/discover which I wish to share with other teachers.
