To learn about the environment, you have helpers.
These are sense organs.
Eyes are the organ of sight.
With your eyes, you can tell the color of things.
Their size and shape.
You find out if they are near or far.
If they move or stay in one place.
Ears are the organ of hearing.
With your ears, you hear all the sounds in the world.
This is people's speech,
music,
animal voices,
the sound of the sea.
Skin is the organ of touch.
It is the biggest sense organ in a person.
With your skin, you can tell what things feel like.
Are they warm or cold?
Are they smooth or prickly?

The nose is the organ of smell.

And they can be nice
or not nice.

The tongue is the organ of taste.
It helps you feel the taste of food.
People can tell these tastes –
sour,
salty,
sweet
and bitter.

Take note!
You learn about the world with your sense organs,
so you need to take care of them.
Don't watch TV for too long and don't read while lying down.
This is bad for your eyes.
Keep your ears clean.
Don't listen to music that is too loud.
Remember, loud sounds are very dangerous.
In cold weather, be careful not to catch a cold.
This will help you keep a good sense of smell.
Don't eat food that is too hot.
And don't forget to rinse your mouth after eating.
Make sure your skin is always clean.
Be careful when using sharp or prickly things.

Tools for exploring help you with this.
With a magnifying glass, look at small details.
With a microscope, look at very tiny things.
With binoculars, look at things that are far from you.
With a telescope, watch your favorite constellations.
Use a ruler to measure the length of things,
and a height meter to measure your height.
You can find out the mass of a body with scales.
And with different thermometers, you can find out the temperature of a body
and the temperature of the air.
