Candy Experiments 2

Gr 3–5—With more than 60 experiments, this sweet sequel to 2013's highly entertaining and educational Candy Experiments (Andrew McMeel) is packed with sugar-coated activities that introduce young scientists to the chemistry behind some of their favorite confections. Organized into nine categories that focus on scientific concepts, including "Density," "Light," and "Crystals," and processes, such as "Dissolve" and "Melt," each experiment features five main components: "Time," "Skill Level," "What You Need," "What to Do," and "What's Happening." Overall, simplicity rules. Supplies are minimal, directions are straightforward and concise, requiring adult supervision only when a microwave or oven is needed, and explanations are rather basic, giving budding candy chemists only the scientific information that's necessary. Sidebars that suggest science fair ideas and extension activities, define vocabulary, and offer fun facts supplement the experiments, providing ample opportunities for additional critical thinking while emphasizing the merits of the scientific process. There's little question that readers will be engaged; the colorful and appealing design and layout, as well as the close-up shots of candy shards, are definite eye-candy. Although the ingredient measurements in "Instant Crystallization" strangely shift from standard to metric, this minor inconsistency has little effect on the book as a whole. A worthwhile addition to science fair collections.—Audrey Sumser, Cuyahoga County Public Library, Mayfield, OH
