The growth of world population puts a severe strain on the earth's principal biological systems. Due to excessive human claims these reach an unsustainable level where their productivity is damaged. Development is not possible if world population continues to grow so rapidly.

For the Motion

Good morning everyone! Respected judges, worthy opponents and the esteemed audience,
Today, I Karuna of class XII, stand before you all to speak in favour of the motion, "The Internet cannot replace a classroom teacher".
The classrooms today differ from the classrooms a decade ago in multitudinous ways. The influx of technology has opened doors, expanded minds and changed the world. However, no matter how advanced and beneficial the technology has got, it can never replace a classroom teacher. There is no denying to the fact that the internet can solve a bulk of problems and provide students all the necessary answers along with illustrations. However, it cannot replace a classroom teacher as it is devoid of any kind of emotion, which is very much required during teaching. A teacher simply does not impart knowledge or information. A teacher leads, guides, facilitates and mentors a student. He understands the emotions and sentiments of the students. He realises the positive as well as the negative feelings of the students.

A teacher faces all types of students with different mental abilities while teaching. He, thus, adjusts his teaching methodology according to them. He helps the weaker students to bloom and motivates his students accordingly. The internet cannot solve all the queries but a teacher can and that too in person. Teachers help the students to remain alert and active in the classroom during teaching, whereas a machine can never do so. Internet would never care about how much concentration, focus and attention the student is learning with. Besides, it can never beat the knowledge of human beings. In addition, it’s not necessary that all the information provided by internet is genuine. Have you ever wondered where all the information or knowledge on the internet has come from? It is only we humans who have fed it into the computers.
In conclusion, I would like to say that a machine can never replace a living and breathing knowledgeable person.

Thank you!

Against the Motion

Good morning everyone! Respected judges, worthy opponents and the esteemed audience,
Today, I Karuna of class XII, stand before you all to speak against the motion, "The Internet cannot replace a classroom teacher".
The classrooms today differ from the classrooms a decade ago in multitudinous ways. These days, a modern classroom is defined by technology. Teachers, administrators, parents and students have been told time and again that it is technology alone through which we can sharpen our education system. True personalised tech-infused learning is the future of education. In today’s age, the old school method of books and notes is no longer beneficial. Teachers have to keep themselves updated with today’s trends and have to equip themselves with the latest technology.
There is constant pressure on teachers and administrators today to implement technology in classroom. In order to fully engage the students and make them learn, a teacher will have to come out of his comfort zone and explore new ways of teaching through the internet. The internet has immense potential to upgrade today’s educational system. There may come a time soon when the role of a teacher in the classroom will considerably be diminished by the internet-based learning environment .
In near future, the teacher will not be able to function without internet and technology. The teacher will have to become a facilitator of imparting trustworthy information from electronic sources. The teachers today need to strike a balance and empower themselves through technology so as to prevent themselves from getting replaced altogether by the internet.

Thank you!

Maria Sharapova had to live alone in the hostel away from her parents.Her mother could not accompany her to USA due to some visa restrictions. His father worked day and night to earn money to pay for her tennis coaching.Thus, she was lonely and she could be easily depressed.However,she had a strong will power and she faced these challenges with ease.

Martians planned to attack the Earth. The ruler of Mars, Think Tank instructed one of his Martian-Noodle to gather information about Earth. He saw that other three crew members-Captain Omega, Lieutenant Iota and Sergeant Oop found some books in Centerville Public Library. A book named 'Mother Goose' contained nursery rhymes. Omega managed to read some nursery rhymes like 'Mistress Mary', 'Humpty-Dumpty' etc. Think Tank completely misinterpreted the rhymes. He thought that Earthlings were intelligent enough in warfare and had advanced technology to grow high exposures. He was shocked to discover that metals could be grown in fields. On seeing the image of Humpty-Dumpty, he thought its head resembled that of his own. He feared invasion on Mars by the Earthlings. So instead of attacking the Earth, he decided to migrate one hundred million miles away from Mars to Alpha Centauri. Hence, the title 'The Book that Saved the Earth' is apt.

Photoelectric effect: When certain metals are exposed to a beam of light, the electrons are ejected from the metal. This phenomenon is called the photoelectric effect. The electrons ejected are called photoelectrons.

The results of this experiment were:

1. The electrons are ejected from the metal surface as soon as the beam of light strikes the surface, i.e., there is no time lag between the striking of the light beam and the ejection of electrons from the metal surface.
2. The number of electrons ejected is proportional to the intensity or brightness of the light.
3. For each metal; there is a minimum frequency, {tex}\nu_o{/tex} below which photoelectric effect is not observed.
4. K.E. of electrons {tex}\propto{/tex} frequency of light.

Equipment for studying the photoelectric effect. Light of a particular frequency strikes a clean metal surface inside a vacuum chamber. Electrons are ejected from the metal and are counted by a detector that measures their kinetic energy:

Explanation of photoelectric effect on the basis of quantum theory: When a photon of sufficient energy strikes an electron in the atom of the metal, it transfers its energy to the electron and the electron is ejected without delay. Greater the energy of the photon, greater will be the kinetic energy of the ejected electron.

The narrator noticed some of the family possessions missing at her home. Her mother informed her that Mrs. Dorling was taking these possessions to her home for safekeeping till the end of the war. She was initially apprehensive about the lady but the rebuking look from her mother was enough to drop the topic. Her first encounter with Mrs. Dorling was also a brief one and she could only catch a glimpse of her broad back.
