Mary Holland wrote the book about animal mouths and provided information as to why certain animals are carnivores, herbivores or omnivores, and how an individual can tell what kind of diet an animal has based on their teeth. The life science idea that is utilized in this book is the different varieties of mouths animals have, ranging from herbivores to carnivores and from turtles mouths to beaks on a bird. This book is very accurate and informative on how they go about presenting the information to children, describes how some animals have teeth and some have beaks, or how they use their jaws to consume their diet. Holland goes into detail on how some animals like birds don’t have teeth, but beaks that they use to crack seeds, or depending on the design of their beak allows them to prey on certain animals. …show more content…
It gives them different perspectives of how other animals, besides humans, don’t have teeth or use their jaws to rip apart their food, or how some just swallow their food whole. By reading the book it allows students to get new perspectives on how certain sets of teeth work out on consuming a particular animals diet. A lesson can be created through this book, and allow students to further investigate and question why certain functions of teeth work the way they do, in order to construct explanations as to why something works the way it does, like a jaw for example. Holland goes into grave detail on how herbivores have flat teeth and molars; members of the rodent family have teeth called incisors that are always growing. Beavers, for example keep their teeth from getting too long from chewing on bark, which erodes away the teeth, but their incisors will always grow back. The book meets the standards because it allows children to observe and investigate, which meets the criteria of New Generation of Science
