1. Earth and Life Science The Universe and the Solar System Prepared by Christy D. Sandoval, RN, MAN, LPT

2. JUMBLED WORDS AGREL IBAGUAMLENNI PXNESEA OF ASG ARSTS SUDT LODUSC DAN OCNISTS OF SPLTANE LXGAAY

3. LARGE UNIMAGINABLE EXPANSE OF GAS, STARS, DUST, CLOUDS, AND CONSISTS OF PLANETS, GALAXY

4. The Universe A huge wide, open space that holds everything from the smallest particle to the biggest galaxy Everything that physically exists throughout all space and time. Approximately about 14 billion years old About 93 billion light years in all direction Undefined whether finite or infinite

5. The Galaxy A large group of stars, gas, and dust held together by gravity Milky Way Galaxy includes the Earth and the Solar System There are billions of galaxies in the universe

6. The Solar System Consists of stars, sun and its orbiting planets Moons, asteroids, comet materials, rocks, and dust Sun is just one star among the billions of stars in the Milky Way Galaxy

7. What is it made of? Space and matter Planets, galaxies, stars, particles, atoms, and empty space Important chemicals 4% of the universes is made up of familiar energy Hydrogen and Helium

8. How did the universe begin?

9. The Big Bang Theory Most commonly recognized cosmological clarification Between 13 and 15 billion years ago, all matter and the known energy were the same and unmanageable Immense explosion allowed all matter and energy to spring from the old and unknown energy

10. The Big Bang Theory After some minutes, the following were formed: Light elements, like helium Forces of nature, like gravity Early stages of galaxies The Milky Way Galaxy was shaped five billion years after explosion

11. The Steady State Theory Hermann Bondi , Thomas Gold and Sir Fred Hoyle The universe looks consistently the same from every spot Stars and galaxies may change but universe will always look the same

12. Faults of Steady State Theory Discovery of Quasars Discovery of Cosmic Microwave

13. The Plasma Universe and the Little Bangs Big Bang never happened Traversed by huge electric current and enormous magnetic field Existed endlessly Galaxies converged slowly over much greater extent Matter is continuously created via a succession of “little bangs”

14. The Plasma Universe and the Little Bangs Quasars are the brightest and distant objects in the known universe Galaxies form at a rate determined by speed at which the universe enlarges

15. Evidences for Big Bang The expansion of the universe Cosmic Microwave Background Radiaton (CMB) – discovered by Arno Penzias and Robert Wilson in 1965 Great quantity of the different elements in the universe

16. ACTIVITY #1: Explaining the Universe Objectives To stimulate the expansion of the universe based on the Big Bang Theory To explain the significance of Big Bang Theory in the formation of the universe

17. Guide Questions: How did the distance from the home dot to each other galaxies change each time you inflated the balloon? Did the galaxies near home or those farther away appear to move the greatest distance? After the activity, is the Big Bang theory a viable explanation for the origin of the universe? Explain your answer.

18. Structure of the Universe Planet is part of planetary system Planetary system is part of galaxy Galaxy is part of galaxy system

19. Birth of the Solar System Planets are born from clouds of gas and dust called NEBULAS (Nebulae) Solar System is probably formed from a nebula called SOLAR NEBULA The gas from nebulas developed solar systems because of two forces: GRAVITY PRESSURE

20. Assignment: Answer the following in your activity/quiz notebook Explain the Big Bang Theory Who discovered cosmic microwave radiation and what does it indicate? What composes the universe and how did the compositions formed? What is the difference between Big Bang and Steady State Theory? List three things that are formed after Big Bang?

21. List three things you have learned about the universe, galaxies, and solar system and how can you apply it to real – life situations/everyday living?
