Finding Stuff Out

Teeth (2x11)

Data de estreia: Set 28, 2013

The Big Question: “Why are human teeth and animal teeth different?” Synopsis: Humans and animals have all different kinds of teeth because they eat all different kinds of things. Harrison finds out lots of new stuff about teeth, including why some are sharp and some are flat, why birds have beaks instead of teeth, and how overworked the poor Tooth Fairy is! My Great Challenge: Herbivore, carnivore or omnivore? Challengers guess if an animal is a meat eater, a plant eater or both based on their teeth. In the Field: Harrison visits his dentist, Dr. Cooperberg, to find out why taking care of his teeth is so important.
