Narrate an experience that shows appearances can be deceiving

Image
A person standing in the railway station dressed in a good looking attire It is a common habit of humans to make judgements at the first look. It does not matter if we are seeing a person or a thing for the first time, our minds do not need to take a second look before coming to a judgement. If we look at a person, we quickly look at his clothes and shoes and come to the assumption that he is poor or rich. The same is the case with things, we decide for ourselves whether a substance is expensive or cheap just by its glittering and glistening. Over time, many learned personalities have taught us to "not judge a book by its cover." Through his various plays and writing, William Shakespeare, the popular eighteenth-century English writer, has sent the message to not fall for outward appearances. I have recently expereinced an incident that explains why is it important to not rely on just outward appearances to make a judgement about a person. I was travelling by train during my s...

"No other subject taught in school is as important as Moral Science." Express your views for or against this statement

Image
For the statement "No other subject taught in school is as important as Moral Science." Express your views for or against this statement A school is where the youngsters are taught the fundamentals in every major subject. They are taught Mathematics, Science, English, Computer Science, and regional language - in India Hindi is taught in most schools. Children till primary schools are taught Moral Science, but in higher grades, it needs to be given more or sometimes no attention. The school forgets how this important subject can help the students to become a better person.  Children are enrolled in schools at an early age. They do not know the ethics and behaviours at such an age. Therefore, it is the responsibility of both - schools and the parents - to teach the children these basic yet important lessons. A person without ethics is no better than a non-living rock. Trees also have ethics; every living organism does. Therefore, it becomes crucial to teach the children the eth...

  Imagine a situation where you get an opportunity to change one thing in your school. What would it be? Why do you want to change it? How would you bring about the change? School is a place where the young generations are bestowed with knowledge and wit. It is a place of education and learning where various subjects are taught to the students without keeping in mind their religion, gender or race. It is the place where everyone is equal and everyone has equal opportunity to get fundamental knowledge in each major subjects.  There are various subjects that are taught in the school. Majority of the subjects are taught in written form as practical lessons would be not possible to conduct for such a large number of students for each subject. But there is one subject that is taught mostly practically in our school and that is Sports.  During the sports period, the students are made to the warm up exercises before the match (which are usually regional games).

Write a story with two students and a teacher as main characters

Image
Write a story with two students and a teacher as main characters There are many instances in which students have to be admitted to a new school or college long after the semester has begun due to various reasons. The reasons could be relocation to another city, seeking better facilities and education or looking for cheaper options.  Due to the mid-semester admissions, the child has to face several hardships and it significantly impacts their mental health and overall performance. The new surroundings of the school could overwhelm them or they could struggle to get familiar with new classmates or teachers. Many students also struggle to keep up with the class work, complete the syllabus and complete homework. The teaching methods of a particular teacher always differ from others, so new students always find it hard to grasp the important points and key concepts. Something like this happened to me too. It was the last working week before the summer vacation. Our teacher, Mr. Singh an...

Abhisara - the Tryst Notes

Image
Upagupta, the disciple of Buddha, lay asleep in the dust by thr city wall of Mathura. Lamps were all out, doors were all shut, ans stars were all hidden by the murky sky of August. Whose feet were those tinkling with anklets, touching his breast of a sudden? He woke up startled, and the light from a woman's lamp fell on his forgiving eyes. It was Vasavadatta the dancing girl, starred with jewels, Clouded with a pale blue mantle, drunk with the wine of her youth. She lowered her lamp and saw the young face, austerely beautiful. 'Forgive me, young ascetic,' said the woman, 'Graciously come to my house. The dusty earth is not a fit bed for you.' The young ascetic answered, 'Woman, go on your way; When the time is ripe I will come to you.' Suddenly the black night showed its teeth in a flash of lightning.  The storm growled from the corner of the sky, and the woman trembled in fear. A year had not yet passed. It was eveing of a day in April, in the Spring. The b...

Essay on visit to a Heritage Site A heritage site is a landmark or a monument of historical importance. United Nations Educational, Scientific and Cultural Organization (UNESCO) administers such sites. They can help us to learn a lot of things about the history and culture of a place. A Heritage site is not only limited to a monument or a landmark but also includes ancient ruins, structures, buildings, cities, deserts, forests, islands, lakes, mountains, and wilderness areas. Schools and Colleges frequently plan a trip to heritage sites to teach the students about their significance, structure, importance, and features. Heritage sites date back several centuries and help students learn about ancient architecture. Students can also learn about primitive ways of living, culture, and faith by visiting and studying these heritage sites. I recently visited a World Heritage site with my classmates and teachers as a part of my school trip for summer vacation. We visited the Konark Sun Temple ...
