A burning log, a rotting banana, and a rusting bicycle. These are examples of chemical changes. With this accessible narrative, readers are introduced to the basics of chemical changes. Easy-to-follow explanations cover matter, forms, properties, and changes. Further detail introduces how to make chemical changes and how to recognize them. Color photographs, fast facts, and an engaging activity expand and reinforce the newly learned ideas. This book supports Next Generation Science Standards, correlating directly with the NGSS Grade 2 standard to "classify different kinds of materials by their observable properties.

Series Review
Children learn about the world around them all the time. This series introduces some helpful terms and concepts for that exploration. Definitions of the terms are provided at the beginning of each book. Short pages of text alternate with images and captions as readers learn about physical and chemical changes, as well as the attributes of matter. Examples such as melting ice cream, a coiled water hose, or a handful of crayons demonstrate physical changes, flexibility, or color in easily understood ways. Fast facts such as “Even people are made of matter” are provided in text boxes to add to the topic. An activity to apply the lessons is included in each book with a materials list and step-by-step directions. A good choice for those looking to update their collection or offer more science titles for the lower grades.
