"Temperature: Heating Up and Cooling Down examines the difference between heat and temperature and describes sources of heat energy. The text includes questions, examples, and explanations. Illustrations reinforce a good foundation of content. The main text of the book is written and illustrated for lower elementary children, with large type and fanciful, computer-generated illustrations. "Fun Facts" throughout the book are printed in a smaller type and have a Flesch-Kincaid level of about grade 5, so primary students will need an adult's support to get the most out of them. Adult help will also be needed for the activity and supporting content material at the back of each book. Structural elements like a glossary and index will help many readers to stretch toward the more challenging parts of the text. Each book also has a special coded password to a "Fact Hound" website and suggestions for library reading."
