Have you ever wondered how your nose knows what you’re smelling? Today, we’re going to explore the amazing sense of smell and how it helps us every day!
Smells are tiny particles or chemicals that float around in the air. These little particles travel through the air and enter our nose through the nostrils. Once inside, they reach a special area called the nasal cavity.
Inside the nasal cavity, there are tiny hairs that help clean and filter the air we breathe. This part of our nose is covered with a wet layer called a mucous membrane, which keeps everything moist and ready to catch smells.
After the air is filtered, it moves to the olfactory membrane. This is a special place where cells gather information about the smells and send it to our brain. The olfactory nerve is like a messenger that carries this information to the brain.
Once the brain receives the information, it figures out what we’re smelling. If we smell something burning, our brain tells us to find out where the smell is coming from and to stay safe.
Did you know that some animals have an even better sense of smell than humans? Dogs, for example, are super sniffers! They can find people who are lost in the woods by following their scent.
And that’s how the sense of smell works! Isn’t it amazing how our nose and brain work together to help us understand the world around us?
If you enjoyed learning about the sense of smell, there are many more fun topics to explore. Keep discovering and having fun!
Smell Detective: Become a smell detective in your own home! With the help of an adult, gather a few items with different scents, like an orange, a flower, or a piece of chocolate. Close your eyes and have someone hold each item under your nose. Can you guess what it is just by smelling it? Talk about how each smell makes you feel and what it reminds you of.
Create a Smell Diary: For one week, keep a diary of all the different smells you notice each day. Write down what you smelled, where you were, and how it made you feel. At the end of the week, share your diary with your class or family. Discuss which smells were your favorites and which ones you didn’t like as much.
Smell and Memory Game: Did you know that smells can help us remember things? Think of a smell that reminds you of a special memory, like the smell of cookies baking or fresh-cut grass. Draw a picture of that memory and share it with a friend or family member. Ask them if they have a smell that reminds them of something special too!

Smile and learn! Today we’re going to learn about the sense of smell.

The smells we can detect are particles or chemical substances floating in the air. These particles travel through the air and enter our nose through the nostrils, reaching the nasal cavity. In the nasal cavity, there are small hairs that clean and filter the air. This part of our nose is covered by a mucous membrane that keeps it moist.
Then, the filtered air reaches the olfactory membrane. This is where we find the cells responsible for collecting the information and sending it to the brain. The olfactory nerve carries this information to the brain, which recognizes and reacts to what we’re smelling.
Once the information has reached the brain, it transmits the necessary signals to react to different smells. For example, if our nose detects a burning smell, we will look for the source of the smell and find a safe place to hide.
Did you know that some animals can detect more smells than humans? Dogs, for example, are great at searching for and rescuing people who are lost in the woods.
That’s how the sense of smell works! Did you enjoy learning about it?
