Germs are all around us, but they're too small to see. Many germs are harmless, but two kinds, viruses and bacteria, can make you sick! How? Read and find out! This classic Level 2 Let's-Read-and-Find-Out picture book is all about germs, how they can make you sick, and how your body works to fight them off.

Now rebranded with a new cover look, this book features rich vocabulary and simple diagrams to explain why you feel poorly when you're sick and how your body keeps you healthy by producing antibodies. Both text and artwork were vetted for accuracy by Dr. Melanie Marin.

This is a Level 2 Let's-Read-and-Find-Out, which means the book explores more challenging concepts perfect for children in the primary grades and supports the Common Core Learning Standards and Next Generation Science Standards. Let's-Read-and-Find-Out is the winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series.
