Your first helpers are your eyes! They are the organ of sight.
Thanks to them, you see the color, size, and shape of things around you.
Eyes tell you if something is far or near, standing still or moving fast!
Your ears are the organ of hearing.
They help you hear every talk, happy music, animal voices, and the magic sounds of nature.
The world around us is full of amazing sounds!
Your skin is the biggest sense organ!
It protects you and works as the organ of touch.
With your palms, you quickly know how things feel: hot or cold, soft or prickly!

You already know there are organs of sight, hearing, and touch.
Besides them, there are other sense organs.
Your nose is the organ of smell.
It helps you tell many smells around you!
Nice smells give us a good mood.
And bad smells warn us about danger.
Your tongue is the organ of taste.
It helps you enjoy food and tell four main tastes:
sour,
salty,
sweet
and bitter.
Each taste is special in its own way!

Your sense organs are a real treasure that you need to protect!
Thanks to them, you learn about the world around you.
To keep your eyes healthy, limit your screen time and never read while lying down.
Always wash your ears when you bathe.
Do not listen to music too loudly to protect your hearing.
In cold weather, always wear a warm scarf!
This will protect your nose from getting a cold and keep your sense of smell great.
To protect your sense of taste (your tongue), never eat food that is too hot.
Let it cool down a little!
After eating, always drink a sip of clean water!
This will help wash away food leftovers and keep your mouth healthy.
Your skin is a protective shield for your whole body!
Make sure it is always clean, and wash your hands with soap more often.
Be super careful when you use sharp things or scissors in class.

Think, which child takes care of their eyes?
Choose the right picture.

You are learning to watch objects of non-living and living nature in the environment.
Tools for exploring help you with this.
If an object is too small, special tools will help you.
Use a magnifying glass to look at tiny details of insects.
And a microscope will help you see very tiny things!
For example: small insects, details of a green leaf, and even invisible microbes.
Binoculars will help you see things that are very far away!
For example: birds in the sky, far mountains, or even this airplane.
And a telescope will show you the amazing world of far stars and constellations.
Scientists always do measurements.
With a ruler, you can find out the length of a pencil.
And this amazing tool is called a stadiometer!
It helps scientists and doctors know exactly how fast you are growing.
And bathroom scales will tell you your body mass!
Stand with your feet on the platform to find out your weight.
And this modern tool is a thermometer!
It can quickly measure body temperature even without touching.
An outdoor thermometer will help you know the air temperature so you can dress right for a walk.

Choose the tools that make things bigger, which you see with your eyes.
