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.
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. The temperature of the air around you varies from morning to night, from season to season, and from place to place. When it changes, processes within your body, such as shivering or sweating, can help you warm up or cool down. You can also change your behavior to adjust your temperature. Animals are able to control their body temperature, too. They do it in many of the same ways you do.
