Super Gross Stinky, Smelly, Projects — page 1 — Super Gross There are tons of super gross things in the world These things can make you feel disgust But did you know this feeling can keep you safe It stops you from touching or eating things that might be harmful Disgusting things can still be fun to think about That’s why many people are fascinated by gross things And stinky smells can be especially gross 4

Super Gross Stinky, Smelly, Projects — page 2 — Gross Smells Some things smell pleasant like a pine forest Others smell disgusting like dog poo or rotten milk Everyone’s sense of smell is a little different A perfume you love might make another person gag Not all gross smells are harmful But your body’s ability to detect bad smells helps keep you safe A rotting smell can warn you about spoiled food The smell of smoke warns you about a fire 5

Super Gross Stinky, Smelly, Projects — page 4 — Smells travel to your nose on odor molecules Everything you smell gives off these molecules And every time you breathe you take them in The inside of your nose is home to millions of tiny hairlike receptors When an odor molecule hits the receptors it sets off a signal The signal travels to your brain Your brain decides whether the smell is pleasant dangerous or just plain stinky 7
