Air and Water Class 1 Notes EVS

Introduction

Air

Air is all around us and is very important for life. It helps us breathe and makes things feel light.

• Invisible and Everywhere:Air is invisible, which means we can't see it, but we can feel it when it moves. It's present both indoors and outdoors, making our world a comfortable place.
• Helps Us Breathe:We breathe in air through our nose and mouth. Air gives us the oxygen we need to live and play.
• Wind is Moving Air: When air moves, we call it wind. Wind can be a gentle breeze or a strong gust, making trees sway and flags flutter.

Types of Air

• Hot, Warm, Cool, and Cold: Air can be at different temperatures, like hot, warm, cool, or cold.
• Breeze: A gentle, slow-moving wind is called a breeze.
• Storm: A storm is a type of severe weather that includes strong winds, rain, thunder, and lightning.

Fun with Air

• Flying Kites: When we fly kites, we feel the air lifting them up into the sky.
• Blowing Bubbles: Blowing bubbles is a fun activity! We blow air into soap to create bubbles, and they float around.
• Helps Birds Fly: Birds use their wings to fly in the air. They rely on the wind to help them glide through the sky.

Air is very important for all living things and plays a crucial role in our environment.

Ways to Keep Air Clean

• No Littering: We should throw our garbage in bins. Keeping our surroundings clean helps to keep the air fresh.
• Planting More Trees: Trees love to breathe air just like us. Planting trees helps keep the air clean and healthy.
• No Smoking:Smoking pollutes the air and is harmful to our health. We should encourage a smoke-free environment.

Water

• Water is a very important liquid that we need to stay alive.
• It is clear and cool, and it can exist in three forms: solid, liquid, and gas, which are ice, water and water vapours. 
• Water is essential for the survival of people, plants, and animals.
• We use water for many things, including:
  (a) Drinking
  (b) Cooking
  (c) Cleaning
  (d) Bathing     
• Plants also need water to grow.

To sum up, water is important for all living beings and is a fundamental part of our everyday activities.

Drinking Water

Types of Water Bodies

• Oceans cover most of the Earth's surface and play an important role in climate and weather patterns.
• Rivers are a fresh water body which flow through high mountains to plains. 
• Lakes are important freshwater body that support animals and plants, provide water for drinking and farming, and are used for fun activities like boating, etc.
• Seas are oceans but smaller compared to them.
• Ponds are smaller lakes.  

How Do We Get Water?

• The main source of water is through rainfall.
• Rainwater is collected in various water bodies such as oceans, rivers, ponds, and seas.
• A part of rainwater also goes deep into the ground, forming what is known as underground water.
• People access underground water using tube wells and hand pumps.
• Additionally, water conservation is an important aspect to consider for future.

Saving Water

• Avoiding Water Waste: We need to use water carefully and not waste it. Always remember to turn off the tap when you’re not using it.
• Keeping Water Clean: It’s important to throw garbage in the bin, not in rivers or lakes. Keeping water clean is good for both animals and plants.
• The Importance of Rainwater: When it rains, it’s like nature giving a big drink to the earth and everything that grows on it. Rainwater is very important for plants and animals.
