Book excerpt: In this fun, fact-packed science book for kids, young readers will discover the bacteria, viruses, and other germs and microbes that keep our bodies and our world running, as well as how and when they can be harmful and the precautions we can take to prevent them from becoming so. Meet a glowing squid, traveling fungus spores, and much more. The Bacteria Book walks the line between "ew, gross!" and "oh, cool!," exploring why we need bacteria and introducing readers to its microbial mates—viruses, fungi, algae, archaea, and protozoa. The Bacteria Book is a fun and informative introduction to a STEM subject that brings kids up-close to the big world of tiny science. With remarkable photography, kooky character illustrations, and lots of fun facts, this book uses real-life examples of microbiology in action to show how tiny microbes affect us in big ways.
