Too Hot? Too Cold?: Keeping Body Temperature Just Right

by Caroline Arnold, Annie Patterson (Illustrator)

Overview

Have you ever wondered why you shiver when you’re cold, or sweat when you’re hot? It may seem natural that emperor penguins huddle together to stay warm in the Arctic, but why exactly does this prevent them from freezing? Is your dog just out of breath when he pants after running around outside, or does panting actually help him to cool down? In TOO HOT? TOO COLD?, Caroline Arnold, acclaimed author of nonfiction for young readers, answers these questions and more.

In clear and concise writing, readers will discover the many different ways humans and animals adapt to heat and cold. The book includes a straight-forward explanation of cold-blooded and warm-blooded animals, and young science enthusiasts will be amazed to learn how remarkably similar animals and humans are when it comes to keeping their body temperatures just right.

Read an Excerpt

If you live in Alaska, you must put on warm clothes when you go outdoors on a cold winter day. If you live in Florida, you rarely need a jacket. Instead, you might take a swim or drink cold lemonade to help your body stay cool.

Editorial Reviews

A fascinating and thorough look at how both animals and humans regulate their body temperatures. Beginning with the difference between warmblooded and coldblooded species (the terms endothermic and ectothermic are introduced but not used), Arnold devotes spreads to such topics as muscle movements, sweating, the shrinking and expanding of blood vessels in the skin, fat, body coverings, and the size and shape of an animal. Behavior can also affect body temperature: animals or humans can seek/avoid the sun or a breeze, cool off or warm up with water, find shelter, or hibernate/estivate/migrate. The one misstep is a minor quibble--a sentence incorrectly states that "No animal can live if its body temperature falls below freezing." The copyright page lists the illustrations as having been done in watercolor and Photoshop, but readers would be hard-pressed to see any evidence of digital artwork here. The spreads and spot illustrations have that blurry, batik quality of watercolors that lends itself so well to nature scenes, while the insets are well-delineated, allowing readers to understand the structures discussed in the text. Every animal is labeled, making this a great jumping-off point for further research into readers' favorites. A glossary and author's note round out the text. A stellar addition to a rather empty shelf. (Nonfiction. 6-10)
