How Your Nose Detects Smells

Iris Fennimore

Press play and shrink down to speck size, then ride a wisp of cinnamon straight up a nostril, slide through sticky mucus, and crash a party where neurons play matchmaker with floating smells. Iris Fennimore turns a biology lesson into a body adventure, best for curious kids around six to ten who like knowing how things actually work. Duncan Winslow reads it like a wise older sibling, clear and unhurried, with just enough hush when the amygdala stores a scary memory and enough pep when signals race to the brain.
