This book in the “Chemtastrophe!” series reminds readers that chemistry, the study of matter, is responsible for most of the products we use daily to look after our bodies. A brief overview of chemistry begins this slim volume. “Fun Facts” sidebars reveal chemistry-related tidbits such that the first chemistry textbook was published in 1789. Inset “How We Know” sections offer historical information, like the chemistry behind hair coloring. Additionally, the scientific method is outlined. Each book in the series provides two simple experiments for readers to try on their own, such as discovering why shampoo cleans.
