Life Class 8th  The dialogue is based on a dramatic poem in Dogri by Ram Nath Shastri and translated into English by Shivnath. The passing wind asks the question - 'What is life?' of various things in the universe like the stars, the moon, the cloud, the ocean, the earth and little girl. Each of them comes out with their definition of life. Now read the text below and find their answers."  Summary of “Life” The prose Life explains the meaning of life through a conversation between the wind and different elements of nature such as the earth, the little girl, the stars, the moon, and the ocean. Each speaker describes life according to their own experience, showing that life does not have one fixed meaning but many interpretations. At the beginning, the wind reflects on its own life. It realizes that life is not just about moving freely but also about responsibility. When the wind brings rain at the right time and place, it helps life grow. This shows that true life involves ...

Resources  (Chapter 1) Class 8th  Notes — Sahil Swe  What is a resource A resource is anything that can be used to satisfy a human need. Items become resources when they are usable (have utility) and therefore have value. Examples: the water you drink, the electricity in your home, a rickshaw used to go to school, textbooks, and vegetables used to make food. Utility (ability to satisfy needs) is what makes something a resource.  Everything available in our environment which can be used to satisfy our needs, provided, it is technologically accessible, economically feasible and culturally acceptable can be termed as ‘Resource’. Utility and value — how something becomes a resource Utility (usability): If people can use something to meet needs, it has utility and becomes a resource. Value: Use/utility gives an item worth. Some resources have economic value (like metals), while others may be valuable socially or culturally but not immediately commercial (like a beautiful ...

How, When and Where  COMPLETE CHAPTER NOTES By Sahil Swe A. UNDERSTANDING HISTORY AND DATES The Traditional View of Dates There was a time when historians were fascinated with dates.     There were heated debates about the dates on which rulers were crowned or battles were fought. · In the common-sense notion, history was synonymous with dates. · You may have heard people say, “I find history boring because it is all about memorising dates.” Is such a conception true? · History is certainly about changes that occur over time. · It is about finding out how things were in the past and how things have changed. · As soon as we compare the past with the present, we refer to time, we talk of “before” and “after”. Common perception: History = memorizing dates of battles, coronations, and events Historical practice: Historians once focused intensely on precise dates of rulers' lives and major events  Modern perspective: While dates provide chronology, history is more about u...

  کاہلی   سر سید احمد خاں سر سید احمد خان کا مضمون "کاہلی" کا خلاصہ سر سید احمد خان کا مضمون "کاہلی" ایک اہم معاشرتی مسئلے پر تبصرہ کرتا ہے۔ ان کا خیال ہے کہ کاہلی صرف ہاتھ پاؤں کی محنت نہ کرنا نہیں ہے بلکہ دماغی اور ذہنی طور پر بھی غیر فعال رہنا ہے۔ وہ دلیل دیتے ہیں کہ جو لوگ اپنے ذہنی قوی کو استعمال نہیں کرتے وہ حیوانوں کی طرح بن جاتے ہیں۔ سر سید کا کہنا ہے کہ ہندوستان میں بہت سے لوگ ہیں جن کے پاس اپنے ذہنی قوی کو استعمال کرنے کے مواقع نہیں ہیں۔ اس کی وجہ یہ ہے کہ ان کے پاس تعلیم اور روزگار کے مواقع نہیں ہیں۔ تاہم، وہ اس بات پر زور دیتے ہیں کہ لوگوں کو اپنی کاہلی کو دور کرنے کی کوشش کرنی چاہیے اور نئے مواقع تلاش کرنے چاہئیں۔ سر سید کا یہ بھی خیال ہے کہ قوم کی بہتری کے لیے ضروری ہے کہ اس کے افراد ذہنی طور پر فعال ہوں۔ وہ لوگوں کو حوصلہ افزائی کرتے ہیں کہ وہ علم حاصل کریں اور سماجی مسائل کے بارے میں سوچیں۔ مضمون کے اہم نکات کاہلی صرف ہاتھ پاؤں کی محنت نہ کرنا نہیں ہے بلکہ دماغی اور ذہنی طور پر بھی غیر فعال رہنا ہے۔ جو لوگ اپنے ذہنی قوی کو استعمال نہیں کرتے وہ حیوانو...
