This nonfiction text is about 50 pages and is divided into 4 chapters. The chapters center around ideas like: the history of sound, natural sound, sound health and conserving the environment. There are many non-fiction text features such as glossary, index, table of contents, text boxes, and bold text to help readers comprehend the text. Quite a bit of text on the page in small font but nice headings help separate content and match the table of contents. I like that this book melds together the scientific areas of sound and nature (physics and biology). The book covers interesting topics such as how the ear works and echolocation. It would be the perfect compliment to a science teacher’s resource collection. As a grade 3 teacher, I could definitely use this book in my lessons, and I would recommend this book to parents and teachers of children in the age 8-12 range. Thank you to NetGalley and the publisher for giving me the chance to read and review this book!
