Earth—Our Shared Home Class 5 The World Around Us Chapter 10 CBSE Notes 2025-26

Earth is our unique blue planet and the only known place in the universe where life exists. From space, Earth appears beautiful, unified, and without borders, reminding us that all humans share one home, even though we come from different regions, countries, and backgrounds.

Understanding Our Home: The Blue Planet Earth is called the Blue Planet because most of its surface is covered by water. When astronauts observe the Earth from space, they see vast blue oceans and green-brown land masses, but cannot spot man-made borders. From high above, only the shape of continents and the endless stretch of water are noticeable. The atmosphere, clouds, and movement of wind also form a layer that covers our world.

Earth Has No Boundaries in Nature In nature, there are no borders. Air, water, clouds, animals, seeds, and even weather patterns travel freely across the globe. For example, the rosy starling, a bird from Russia and Mongolia, visits India every winter. These birds help farmers by eating pests like locusts and grasshoppers. Such examples show the connections between distant places and people, making clear that all living things are part of a larger, global web of life.

How People and Cultures are Connected We connect with the rest of the world in many ways, not only through nature but also through trade, travel, festivals, and shared traditions. The food we eat, the clothes we wear, toys, music, and even stories often come from far-off places. For example, chillies, potatoes, and tomatoes originally came from South America, while practices like yoga began in India and spread worldwide.

Stories of Shared Gifts and Journeys

• Travelling Birds: Rosy starlings fly long distances from cold countries to India, showing how animals connect lands.
• Yoga: Developed in India over 3,000 years ago, yoga is now practised in countries all around the world for health and peace.
• Chilli and Sugar: Chillies came to India from South America, while sugar-making techniques from India travelled to other lands. Both became important in new cultures.
• The Mexican Marigold: Marigolds, originally from Mexico, are now an important part of Indian celebrations.
• Indian Cows in Brazil: Certain Indian breeds of cows were taken to Brazil by traders and became essential to their dairy industry.

Trade, Travel, and Sharing Over time, goods and ideas have travelled worldwide. Spices like pepper and cardamom from India were once called "black gold" and traded along routes connecting continents. Similarly, paper came to India from China, and games like chess and snakes and ladders began in India. Through these exchanges, people shared knowledge, stories, games, and inventions, helping cultures grow.

Learning from Nature and Each Other Nature and people both share what they have, teaching us the importance of caring for one another and the planet. Even the Ministry of Environment, Forest and Climate Change (MoEFCC) logo reminds us that humans and nature must balance and protect each other. Seeds, animals, and even customs can travel and adapt, helping others in new places.

Celebrations and Connections Cultures around the globe use gifts from far-off lands in their festivals and daily life. For example, both Indian and Mexican cultures use marigold flowers during festivals because their vivid colours symbolize joy, spirituality, and warmth. Similarly, foods, musical instruments, and clothes in your home might have stories of travel from other countries.

One Earth, One Family The idea of ‘Vasudhaiva Kutumbakam’ means that the whole world is one family. This wisdom from ancient India encourages respect, care, and harmony among all people, animals, plants, air, water, and land. Every action that helps nature or another person is a step towards living as a global family.

Ways to Care for Our Shared Planet

• Keeping our surroundings clean and planting trees
• Saving water and not wasting energy
• Respecting and helping people, animals, and plants
• Sharing, learning, and working together for a healthy Earth

Reflecting on Change and Growth As time passes, new foods, customs, music, games, and ways of life spread from place to place. Interviewing elders can help us learn how things have changed, what new traditions or foods have appeared, and where they originally came from. Using maps and globes, you can trace the journeys of many familiar things around you.

Seasons’ Journal: Observing Our Surroundings Keeping a journal about the changing world around you helps track the changes in plant life, animal activities, weather, water, and human habits through each season. Simple notes or drawings of what you observe make you more aware of how life on Earth is always moving and evolving.

Sample Format for Seasonal Observation

All the stories and facts in this chapter remind us to learn, share, and care for each other and for our planet — not just for ourselves, but for everyone and the future of Earth. By seeing the world as one family, we build respect, peace, and hope for all living beings.
