Okay so goodmorning everyone before anything else since this is my first time to be your student teacher let me introduce myself again. I’m mr. Rafael remoroza madolin. 22, Single. So starting today together with my colleague over there the gentleman mr. ________ we are tasked with the subject Physical Science. Okay so familiar ang physical science? So first time pud ko ani nga subject no so please bear with me. Kung naa tay malisdan. We can browse thru the internet. Okay so lets start. Ok mangutana sako daan if mao pabani ang sugod ang nga subject PHYSICAL SCIENCE or nag tackle namo ani atong niage. Ok so introduce sa nako ang subject ha. PHYSICAL SCIENCE Physical science is a branch of natural science that studies non-living systems, in contrast to life science. The four main branches of physical science chemistry, geology, physics and astronomy. So base saakong pag basa2 daghan diay nig numbers nga subject no. murag base sainyong nat exam gahapon murag paborito kayo ninyong math kay pas2 man kayo. Mga bright siguro ning humms ug math. Ok lets start. Can any anyone please tell what “theory” how the universe started? (btw, ang mag hatag ans. Ani I record kay hatagan daw ni maam og special points sa oral participation) What? Name , Yes it is the bigbang theory. So what is the bigbang theory Okay so our topic today is about the formation of light elements in the big bang theory According to the big bang theory approximately 13.7 billion years ago the universe started with a singularity. ( a point with all of space, time, matter and energy) in these Singularity- a point in space and/or amoment in time where theuniverse was infinitely hot and dense. In these moment there was no where, when or what. There is even no space around it. – just nothingness THEN ALL OF IT BEGAN TO RAPIDLY EXPAND IN A PROCESS KNOWN AS (INFLATION) is a theory of exponential expansion of space in the early universe. The inflation mostly lasted from 10 −36 seconds. space, itself, expanded faster than the speed of light. DURING THESE MOMENT NAAY NABUO NGA MATTER AND ANTI-MATTER BUT THEY CANCCELLED EACH OTHER BACK INTO ENERGY IN A PROCESS CALLED ANNIHILATION - in physics, reaction in which a particle and its antiparticle collide and disappear, releasing energy. Okay after nag annihilation ang excess matter from annihilation came together Lets take a look how the light elements are formed *electrons *protons- A proton is a subatomic particle found in the nucleus of every atom. The particle has a positive electrical charge, equal and opposite to that of the electron. *neutrons- neu·tron a subatomic particle of about the same mass as a proton but without an electric charge And other particles When nag mix ang proton ug neutron nakabuo ni siyag nucleus in the process callled Nucleosynthesis is the creation of new atomic nuclei, the centers of atoms that are made up of protons and neutrons. Then much later on nagsimula ng humalo ang electrons which formed sa pinakamaliit na bagay na tinatawag na ATOM then with the lot of atoms it created a gravity strong enough para ang mga atoms maghalohalo and makabuo ng STARS. So with these it formed of what we are today. EARTH and galaxies. To be more scientific let us try to look closely on how the LIGHT ELEMENTS ARE FORMED. Starting daari Paki write down nalang dayon ko Kung mag halo ang 1 proton and 1 neutron makabuo ito ng DEUTERIUM OR 2-1H Kung mag halo ang isang proton and dalawang neutron makabuo ni siya ug TRITIUM OR 3-1H PERO kung proton lang ang nasa sulod ng nucleus and nay is aka electron sa gawas. Makabuo pa gyapon ng isang katauhan ng hydrogen 1-H o PROTIUM Kani sila tulo pare parehas na isotopes of HYDROGEN BASICALLY THESE THREE ANG UNANG NABUO NGA ELEMENT SA BIG BANG KAYA HYDROGEN ANG NAA SA TAAS AT PINAKA UNA SA PERIODIC TABLE KAY HYDROGEN ANG MAY PINAKAMALIIT NA LAMAN NG PROTON SA LOOB NG NUCLEUS ANG TINATAWAG DIN NATING ATOMIC NUMBER. Question hydrogen lang ba ang nabuo nga element mula sa big bang. Hindi meron pang tinatawag na light elements kasi ofcourse magagaan palang ang kanilang laman ng nucleus kagaya ng Helium (HE) LITHIUM (LI) SO THAT IS HOW THE LIGHT ELEMENTS ARE FORMED THRU THE BIRTH OF OUR UNIVERSE ACCORDING TO THE BIGBANG THEORY. Activities: balloon 2 dots. Why do the stickers appear to be moving away from each other? So with this simple example the evidence proves that the universe is expanding because the earth is getting farther from other stars ( the balloon examples as the universe and the 2 dots examples as the earth and stars)
