Quiz: Long Throats, Loud Roars (Age 11)

1. 1

   Why can a lion roar more deeply and loudly than a small cat?

   • Its stretchy throat cartilage makes a longer, wider air space.
   • Its tongue is rougher and scrapes the air.
   • Its fur traps sound close to its neck.
2. 2

   What happens to sound when air passes through a long, wide tube in the throat?

   • It becomes deeper and louder.
   • It becomes higher and softer.
   • It disappears before leaving the mouth.
3. 3

   What is the main job of the stretchy cartilage in a roaring cat’s throat?

   • It opens up a bigger air space for sound to resonate in.
   • It closes the throat so no air can move.
   • It changes the colour of the cat’s fur.
