In this edition of the “Rookie Read-About Science” series students are given a behind the scenes look at the humble beginnings of everyone’s favorite sweet treat. Simple sentences and well-placed information bubbles take young readers on a trip from pods hanging from cacao trees in a tropical forest to the formation of a chocolate bars in a modern factory. Each page has a full color spread on one side and one or two simple sentences on the opposite page with key words in bold. Curriculum links include: a step-by-step chart, a picture glossary, index, and a website for students to visit for more information on how chocolate is made. Other books in the series include: Milk to Ice Cream, Tomatoes to Ketchup, and Trees to Paper. Reviewer: Tanya Cristini Klatt AGERANGE: Ages 3 to 6.
