Here are three easy ways to say that idea for a 6-year-old:
- Smell happens when tiny bits from things float into your nose and tickle nerves that tell your brain what you are smelling.
- When little particles from food or flowers get to your nose, they touch special nerves and send a message to your brain — that is how we smell.
- Smell is when tiny pieces in the air reach your nose, tickle nerve endings, and then those nerves tell your brain what the smell is.
