Our Body

Class 3

🎯 Learning Objectives

📖 Let Us Begin!

Stand up and look at yourself. You have a head, two hands, two legs, and so many other parts! Your body helps you run, play, eat, read, and do everything.

Your body also has five special helpers called sense organs. They help you see, hear, smell, taste, and feel the world around you.

Let us learn about our wonderful body and how to take care of it!

External Parts of Our Body

The parts of the body that we can see from outside are called external parts.

Think about it: How many things can you do with your hands? Writing, eating, clapping, waving -- your hands are very busy!

The Five Sense Organs

We have five sense organs. Each one helps us understand the world in a different way.

Sense OrganSenseWhat It Does
EyesSightHelp us see colours, shapes, people, and things
EarsHearingHelp us hear sounds, music, and voices
NoseSmellHelps us smell flowers, food, and smoke
TongueTasteHelps us taste sweet, sour, salty, and bitter things
SkinTouchHelps us feel hot, cold, soft, hard, rough, and smooth
Close your eyes and touch a ball. Can you tell if it is smooth or rough? That is your skin (sense of touch) at work!

Taking Care of Our Body -- Good Hygiene

Hygiene means keeping our body and surroundings clean. Good hygiene keeps us healthy and free from germs.

Key Points to Remember
Examples from Daily Life
Example 1: Sense Organs at School

In class, Priya uses her eyes to read the blackboard, her ears to listen to the teacher, and her hands to write in her notebook. At lunch, she uses her tongue to taste her paratha and her nose to smell the pickle.

Example 2: Good Hygiene at Home

Every morning, Aman brushes his teeth, takes a bath, and wears a clean uniform. Before eating breakfast, he washes his hands with soap. These good habits keep Aman healthy and fresh all day.

Example 3: Playing in the Playground

When Neha plays in the playground, she uses her legs to run, her arms to catch the ball, and her eyes to watch where the ball goes. After playing, she washes her hands and face.
