What are germs—and why do they sometimes make us sick?
In this classic Let’s-Read-and-Find-Out Science book, Melvin Berger introduces young children to the tiny world of bacteria and viruses, explaining in clear, approachable language how germs affect our bodies and how our bodies work to fight them off.
Illustrated by Marylin Hafner, it’s an engaging vintage introduction to the science happening inside us every day.
