Air and Water Class 1 Notes EVS

Air 

Air is all around us, even though we can't see it! It's like a big, invisible blanket that helps us breathe and makes everything 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 everywhere, inside and outside, making the world a comfy place.
• Helps Us Breathe: We breathe in air through our nose and mouth. It gives us the oxygen we need to live and play.
• Wind is Moving Air: When air moves, we call it the wind. It can be a gentle breeze or a strong gust, making the trees dance and flags flutter.

Air can be hot, warm, cool and cold. 

Moving air is called wind. Slow moving and soft wind is called breeze. A very strong wind with thunder and lightning is called a storm.

• Flying Kites: When we fly kites, we feel the air lifting them up high into the sky. It's like giving them a ride on the invisible wind!

• Blowing Bubbles: Blowing bubbles is so much fun! We use our breath to make the air inside the soap bubbles, and they float around.
• Helps Birds Fly: Birds have wings that help them soar in the air. They use the wind to glide and move through the sky.

Keeping Air Clean

• No Littering: We should throw our trash in the bins. Keeping our surroundings clean helps keep the air fresh.
• Planting Trees: Trees love to breathe air just like us. Planting trees helps keep the air clean and healthy.

Planting Trees

• No Smoking: Smoking is not good for the air or our health. We should encourage everyone to keep the air smoke-free.

Water 

Water is a super special liquid that we need to live! It's clear, cool, and can take different forms, like ice and steam. People, plants and animals need water to live. We also need water for drinking, cooking, cleaning and bathing. Plants need water to grow.

Drinking Water

Types of Water Bodies 

Did you know, there is more water on earth than land? Take a look at some water bodies.

How Do We Get Water?

The main source of water is rain. Rainwater gets collected in oceans, rivers, ponds and seas.
Some rainwater goes deep inside the ground. This water is known as underground water. People use tube wells and hand pumps to draw out underground water.

Taking Care of Water

• Not Wasting: We should use water wisely and not waste it. Turn off the tap when you're not using it.
• Keeping Water Clean: Throw trash in the bin, not in rivers or lakes. Keeping water clean helps animals and plants.
• Rainwater is Nature's Drink: When it rains, it's like nature giving a big drink to the earth and everything growing on it.
