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.

Head -- has our hair, forehead, eyes, ears, nose, and mouth.
Neck -- joins the head to the body and helps us turn our head.
Arms and Hands -- help us hold, write, eat, and carry things.
Legs and Feet -- help us walk, run, jump, and kick.
Chest and Stomach -- the middle part of our body.
Fingers and Toes -- we have 10 fingers and 10 toes.

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 Organ	Sense	What It Does
Eyes	Sight	Help us see colours, shapes, people, and things
Ears	Hearing	Help us hear sounds, music, and voices
Nose	Smell	Helps us smell flowers, food, and smoke
Tongue	Taste	Helps us taste sweet, sour, salty, and bitter things
Skin	Touch	Helps 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.

Take a bath every day with soap and water.
Brush your teeth twice a day -- morning and before bed.
Wash your hands with soap before eating and after using the toilet.
Keep your nails short and clean.
Wear clean clothes every day.
Comb your hair neatly.
Eat healthy food and drink plenty of water.
Sleep for 8 to 10 hours every night.
Play and exercise every day to keep your body strong.

Examples from Daily Life

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.
