- Match each sense organ to the sense it gives you (sight, hearing, smell, taste, touch).

Five Organs, Five Senses
You have five sense organs, and each one gives you a different sense. Your eyes give you sight, your ears give you hearing, your nose gives you smell, your tongue gives you taste, and your skin gives you touch. Each organ is built to notice one main kind of information, like light, sound, smells, flavors, or pressure.
Senses Send Messages to the Brain
A sense organ does not understand the world by itself. When your eyes see light or your ears catch a sound, the organ sends a message through nerves to your brain. Your brain reads all these messages and figures out what is happening, like deciding that a sound is a dog barking. The organ collects, and the brain understands.
Senses Keep You Safe
Your senses do more than help you enjoy the world; they also protect you. Your nose can warn you of smoke or spoiled food, your skin can feel something too hot before it harms you, and your eyes and ears spot danger from far away. Working together, your five senses help you make safe choices every day.
Worked examples
Choose the sense organ for hearing a bell.
- A ringing bell makes a sound that travels through the air.
- The organ that picks up sounds is the ears.
- So you use your ears to hear the bell.
Answer: You use your ears to hear a ringing bell.
Explain why tasting and smelling are different senses.
- The tongue senses flavors like sweet, salty, sour, bitter, and umami.
- The nose senses smells in the air, which is a different organ and sense.
- So taste and smell are two separate senses, even though they often work together.
Answer: Taste comes from the tongue and smell comes from the nose, so they are different senses.
Activity
Drag each picture to the sense organ you use most to learn about it. Think about the ONE sense you are using most with each picture.
Practice
List each of the five sense organs and the sense it gives you.
Why does a sense organ need your brain to make sense of what it finds?
Common mistakes to avoid
- You taste food with your nose.Your tongue tastes food while your nose smells it; they are two separate sense organs.
- The tongue is the main organ for feeling temperature.Your skin covers your whole body and is the main organ for feeling warm, cold, and touch.

Recap
Your five sense organs are eyes, ears, nose, tongue, and skin, and they give you sight, hearing, smell, taste, and touch. Each one collects information and sends messages to your brain, which figures out what is happening around you.
Reflect
Which sense do you think you would miss the most, and how would you adapt without it?
