Let Us Begin!
Our body is amazing! It helps us walk, run, eat, see, hear, and do so many things.
We have many body parts. Each part has a special job to do. We must take good care of our body.
Let us learn about our wonderful body!
Parts of Our Body
Our body has many parts. Here are the main ones:
| Body Part | What It Does |
|---|---|
| Head | It is at the top. Our brain is inside the head. It helps us think. |
| Eyes | We use eyes to see things. |
| Ears | We use ears to hear sounds. |
| Nose | We use the nose to smell and to breathe. |
| Mouth | We use the mouth to eat, drink, and talk. |
| Hands | We use hands to hold, write, and do work. |
| Legs | We use legs to walk, run, and jump. |
Think about it: What would happen if we could not use our hands? How would we write or eat?
Our Five Senses
We have five senses. Each sense uses a different body part:
| Sense | Body Part | Example |
|---|---|---|
| Sight (seeing) | Eyes | We see colours, shapes, and people. |
| Hearing | Ears | We hear music, voices, and sounds. |
| Smell | Nose | We smell flowers, food, and rain. |
| Taste | Tongue (in mouth) | We taste sweet, sour, salty, and bitter food. |
| Touch | Skin (all over body) | We feel hot, cold, soft, and rough things. |
Sita closed her eyes and smelled something sweet. She said, "It is a mango!" She used her sense of smell.
Keeping Our Body Clean
We must keep our body clean every day:
Bath every day to keep skin clean. Brush teeth twice a day. Wash hands before eating and after using the toilet. Cut nails regularly. Wash hair twice a week. Wear clean clothes every day.
Our Sense Organs
The body parts we use for our five senses are called sense organs. Each sense organ has a very important job:
| Sense Organ | Sense | How It Helps Us |
|---|---|---|
| Eye | Sight | Helps us see colours, shapes, faces, and danger. We can read, watch, and enjoy the world around us. |
| Ear | Hearing | Helps us hear sounds, music, voices, and warnings. We can listen to our teacher and enjoy songs. |
| Nose | Smell | Helps us smell food, flowers, and danger (like smoke or gas). It also helps us breathe. |
| Tongue | Taste | Helps us taste four flavours — sweet, sour, salty, and bitter. It also helps us speak clearly. |
| Skin | Touch | Covers our whole body. Helps us feel hot, cold, pain, pressure, and texture (smooth or rough). |
Ravi touched a hot cup of tea and quickly pulled his hand away. His skin felt the heat and warned him. The sense of touch kept him safe!
We must take care of our sense organs:
- Do not read in dim light — it strains the eyes.
- Do not listen to very loud music — it can harm the ears.
- Do not put anything sharp inside the nose or ears.
- Eat a variety of foods to keep the sense of taste healthy.
- Apply sunscreen and moisturiser to protect the skin.
Taking Care of Our Body
Our body is a gift. We must take good care of it every day. Here is how:
| Good Habit | Why It Is Important |
|---|---|
| Exercise daily | Makes our muscles strong. Keeps us fit and active. Walking, running, cycling, and playing are all good exercise. |
| Eat healthy food | Gives our body the energy and nutrients it needs to grow and stay strong. Eat fruits, vegetables, dal, and milk. |
| Drink enough water | Our body needs 6–8 glasses of water every day. Water keeps us hydrated and helps our body work properly. |
| Sleep 8–9 hours | Our body grows and repairs itself while we sleep. Children need 8–9 hours of sleep every night. |
| Wash hands before eating | Removes germs and dirt. Keeps us safe from illness. |
| Brush teeth twice a day | Keeps teeth clean and strong. Prevents tooth decay and bad breath. |
| Bathe every day | Removes sweat, dirt, and germs from the skin. Keeps us fresh and healthy. |
| Sit and stand straight | Good posture keeps our back and spine healthy. |
Meena wakes up at 6 am. She brushes her teeth, bathes, and eats a healthy breakfast. After school, she plays outside for 30 minutes. At night, she sleeps by 9 pm. Meena takes great care of her body!
