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 ...

Division of Dates in History (BCE & CE) 1. Meaning of Division of Dates The division of dates in history refers to the method used by historians to organise, record, and interpret past events by dividing time into clearly defined eras. Since human history stretches across thousands and even millions of years, a systematic dating system is essential. This division helps historians and learners to: Understand the chronological order of events Compare historical developments across different regions and civilizations Study history in a systematic, scientific, and organised manner Avoid confusion while referring to ancient and modern periods 2. Main System of Historical Dating The most widely accepted system of historical dating across the world is based on the birth of Jesus Christ. This system divides time into two major eras: BCE (Before Common Era) or Before Christ CE (Common Era) or Anno Dommini This system is internationally recognised and used in textbooks, research, archaeolog...

Beauty- John Edward Masefield About the Author Having lived a life of both profound hardship and celebrated artistry, John Masefield (1878-1967) became one of England’s most cherished and accessible poets. His story reads like one of his own adventure tales. Orphaned as a boy, he was sent to sea at 13, a brutal apprenticeship that gifted him the nautical language and yearning for the horizon that would make him famous. He famously deserted his ship in New York, living a hand-to-mouth existence while educating himself in public libraries—an experience that grounded his later work in the realities of struggle. He returned to England determined to write, and his deep, resonant voice, which spoke of salt spray and the human spirit, eventually earned him the highest poetic honor: he was appointed Poet Laureate in 1930, a role he served with dedication for 37 years. Masefield’s genius lay in his ability to speak to both the common reader and the literary critic. He is best remembered for a h...

 The 43-Second Descent- Why the History of Hiroshima is Darker Than Your Textbooks Claim 1. The Day the Sun Descended: A Monday Morning Like Any Other A deceptive peace hung over Hiroshima on the morning of Monday, August 6, 1945. Summer was in full force, the sky was a clear, pleasant blue, and the sun was shining with a warmth that betrayed nothing of the impending furnace. At 8:00 AM, the city hummed with the mundane rhythms of a society at war but still functional: adults were filing into their offices, and children had just settled into their classrooms for the first period of the school day. The tranquility was briefly punctuated by the sighting of an American Boeing B-29 aircraft high in the sky. To the residents below, it was a distant speck; at 8:15 AM, when an object was released from the plane, people watched with a curious, oblivious detachment. Even in their wildest dreams, they could not have imagined what was falling toward them. For exactly 43 seconds, the city rema...

Chapter: The Fundamental Unit of Life Introduction: Discovery of Cell In 1665 , Robert Hooke observed a thin slice of cork under a self-designed microscope. He noticed that cork looked like a honeycomb made of many small compartments. 🔹 Cork is obtained from the bark of a tree 🔹 These compartments were empty because cork cells were dead 🔹 Hooke named these compartments “cells” Cell is a Latin word meaning “a little room” Importance of Hooke’s Discovery First evidence that living organisms are made of small structural units Laid the foundation of Cell Biology The term cell is still used today What are Living Organisms Made Up of? All living organisms—plants, animals, and microorganisms—are made up of cells . Some organisms consist of: One cell → unicellular organisms Many cells → multicellular organisms Activity 5.1 – Observation of Onion Peel Cells Aim To observe the structure of cells in an onion peel under a microscope. Materials Required Onion bulb Forceps Wa...
