In this Short Activity, learners sniff a series of diluted scent solutions to discover they can smell nano-sized particles they can’t see.
“Exploring Size – Scented Solutions” is a hands on activity illustrating how small nano is. By sniffing a series of diluted scent solutions, visitors discover that nano-sized particles may be too small to see, but they’re not too small to smell!
Nanoscale science focuses on things that are too small to see, including atoms and molecules.
- A nanometer is a billionth of a meter.

Nanometer-sized things are very small, and often behave differently than larger things do.
