Topic: The Universe
Grammar Section: Indirect Question
TEACHER: OK, Class. Today, we will talk about the Universe. Can anyone tell me what you know about the Sun?
GAMA: It’s the nearest star to the Earth and also the center of our Solar System.
TEACHER: Good, Gama! That’s right. Now does anyone know how long it takes the Earth to revolve around the Sun?
FIKKRY: It takes three hundred sixty five and a quarter days.
TEACHER: Wow! Perfect, Fikkry! That’s why we have A LEAP YEAR every four years, and the leap day goes to . . . . ?
FIYA: February 29th.
TEACHER: Smart girl! Were any of you born on that day?
CICI: Me, Teacher. My father usually celebrates my birthday once per four years.
TEACHER: It must be so special to you, Cici.
CICI: Sure. Thanks, Teacher.
AGUNG: It is because the existence of the Sun’s gravity.
TEACHER: Correct! Can you explain more, Agung?
JANI: Let me do it, Teacher.
TEACHER: OK. Go ahead.
JANI: Every object in this universe moves. The lighter objects orbit the heavier one. The sun is 1000 times heavier than the largest planet, Jupiter. That’s why every planet, including the Earth, can go around the Sun consistently on its orbit.
TEACHER: Excellent, Jani! Now I’d like to know if any of you dream to be an astronaut or astronomer.
DANANG: Be careful you may not get back!!
STUDENTS: Aahaa..ha…ha…..! [ten seconds of laughter]
TEACHER: Awesome! You ought to make your dream come true, Qisth. Don’t give up!
QISTH: Thanks, Teacher.
TEACHER: Well, students. At this point, any questions?
HIDA: I wonder why the Earth is the only habitable planet.
TEACHER: Good question, Hida! I’ll explain that. The Earth is at the right distance from the Sun. It makes the right temperature for life. It is protected from harmful solar radiation by its magnetic field. It is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon. No other planets have all these features. It makes the Earth the only planet we can live on.
HANI: I heard that the scientists found some planets outside our solar system that look similar to our Earth. Do you think there is any life on those planets? Would it be possible for us to live there?
TEACHER: Thanks for the question, Hani. Yes, time to time scientists searched and found those planets. Just remember! There are billions and BILLIONS of stars in our Galaxy alone, and each star is supposed to have at least one planet. Thousand planets were found and some of them look similar to our beloved planet. The distance to the star (as the center of solar system), the size, and the elements of the planets are almost similar to our habitable planet. Yet, until today, they haven't found any evidence of life there. IF one day we EVEN find a habitable planet, we will get old or even die before reaching it. IF ONLY there were a vehicle moving as quickly as the light does, 300.000 km/second . . . Probably we can take a walk in our Galaxy.
AINUR: How long will it take us to reach the boundary of our solar system?
TEACHER: Good question, Ainur! Let me first ask you a question. Have you ever heard about Voyager 1?
STUDENTS: . . . . . . [shaking the head]
TEACHER: No body? OK. I will explain.
It is the spacecraft launched on September 5th, 1977. With the speed of about 17 km/second, it is the only spacecraft that reaches the farthest distance from the Earth, the boundaries of our solar system. Scientist said it needs at least 36 YEARS to reach the boundary of our solar system. Until today, this spacecraft has still been in communication with the Earth and is keeping on moving away from the Sun. Now can you imagine how long it will take you to reach a planet outside our Solar System? :D
ALDI: Let’s just go by Doraemon’s DOOR, Teacher.
TEACHER: Good idea, Aldi! :)))
TEACHER: Well, dear students, you’re all amazing today. You must have read your book last night.
VIRA: Teacher......you have explained it so many times……. [LOL…….] *kidding
