SMELL


WHAT ARE SMELLS?

What make us smell?When you can't see something,it doesn't mean there's something there.The smell is just made of things too small for your eyes to see.You know they're there because you can smell them.

HOW DO WE SMELL?

We smell through our nose.There are cells inside the nose that reconize different smells.These cells send signals along the nerve to the smell center in your brain.It senses the odour that you smell.Whether it smells bad or good,depends on your sense of smell.

DID YOU KNOW?

A type of dog called the BLOODHOUND can smell at least 1000 times better than humans!
