Watch Them Grow: The Fascinating Science of Animal Beginnings

Gr 5-8–Former educator Pearson has written an intriguing elementary science book, explaining when and why animals develop the way they do and showing different animals in different phases prior to birth. While pictures of creatures from bats to snakes to elephants in utero or egg may be deemed “gross” by some younger readers, others will flock to this title for precisely that same reason; they can read about “gross” things without getting in trouble, because it’s scientific! Students will learn many facts related to fetuses in nature, such as why a mouse grows its whiskers before it is born or how great white sharks give birth to live young instead of laying eggs. Great explanations of cell division, DNA, and chromosomes in the opening chapter lay groundwork for the five remaining chapters. Diagrams are clear and appropriate for younger readers. Backmatter includes a glossary, a short mention of how scientific names are determined, and an invitation to give “baby gifts” to animals, like protecting habitats or minimizing pesticide use. A short explanation of how mating occurs is only mentioned in conjunction with an explanation of genetics. The use of the color green adds to the overall nature-loving aspect of this book, and though it is text-heavy, the text is all one font, making it easy to read.
