Short Summery of chapter 15 Air Around us Class 6 Science NCERT Cbse

The chapter “Air around us” in Class 6 Science introduces students to the concept of air, its composition, and its importance. It explains that air is a mixture of gases and occupies space. The main components of air are nitrogen, oxygen, carbon dioxide, and other gases in smaller amounts. It also discusses how air is present everywhere and is essential for various life processes.

The chapter explores the properties of air, such as its weight, transparency, and ability to exert pressure. It explains that air has mass and therefore exerts pressure on objects. This pressure is known as atmospheric pressure and is responsible for various phenomena like wind, flight, and everyday activities.

Furthermore, the chapter delves into the importance of air for living organisms. It describes how living beings, including humans, plants, and animals, require oxygen from the air for respiration. It also highlights the role of air in the water cycle, the process of photosynthesis, and the dispersal of seeds.

In addition to the properties and significance of air, the chapter may cover related topics such as pollution and conservation. It might discuss the sources and effects of air pollution, as well as the measures to reduce pollution and preserve the quality of air.

The chapter “Air around us” in Class 6 Science introduces students to the fascinating world of air and its significance in our daily lives. It explores the composition of air, its properties, and the vital role it plays in supporting life on Earth.

Air is an invisible mixture of gases that surrounds us. It occupies space and has weight. The primary components of air are nitrogen, oxygen, and small amounts of carbon dioxide and other gases. Nitrogen forms the largest portion of the air we breathe, accounting for about 78%, while oxygen comprises approximately 21%. Carbon dioxide, though present in a relatively small proportion (around 0.04%), plays a crucial role in maintaining the Earth’s temperature through the greenhouse effect.

Understanding the properties of air is essential in comprehending its behavior and impact. Air is transparent, meaning we can see through it, allowing us to observe the world around us. It is also elastic, which means it can be compressed or expanded. The concept of air pressure is introduced, explaining that air has weight and exerts pressure on objects. This pressure, known as atmospheric pressure, is responsible for phenomena such as wind and is the reason we feel pressure changes in our ears during changes in altitude.

The chapter explores the importance of air for living organisms. Humans, animals, and plants all depend on air for survival. Animals and humans need air to breathe and obtain oxygen for the process of respiration. Plants, on the other hand, use carbon dioxide from the air and sunlight to carry out photosynthesis, a process that helps them produce food. The chapter also explains how air is involved in the water cycle, facilitating the evaporation of water from oceans and bodies of water, its condensation into clouds, and its eventual precipitation as rain or snow.

While air is essential for life, it can also be affected by pollution. The chapter might cover the sources and effects of air pollution, including the release of harmful gases from industries, vehicles, and burning of fossil fuels. It might also highlight the importance of conserving air quality through measures such as reducing pollution, promoting renewable energy sources, and adopting sustainable practices.

In conclusion, the chapter “Air around us” in Class 6 Science provides an in-depth understanding of the composition, properties, and importance of air. It highlights the role of air in supporting life, its impact on weather patterns, and the need for preserving air quality. By studying this chapter, students develop a comprehensive understanding of the significance of air and become more aware of their responsibility in protecting and conserving this precious resource for future generations.
