Candy Experiments Series, Book 1

April 1, 2013

Gr 3-6-This book of tricks with treats coats scientific principles and properties like molecular structure and attraction, and volume, mass, and density with layers of sugar. Grouped by physical properties that include "Color," "Secret Ingredients," and "Sticky" or processes like "Blow It Up," "Squash It," and "Dissolve This," the activities begin with an introductory question and tend to flow incrementally. Each one includes the time required, a list of ingredients (mostly found in the candy aisle), step-by-step directions, and a discussion, including a cursory scientific explanation. A follow-up variation extends the inquiry. Skill levels have more to do with safety concerns and manual dexterity than concepts covered. Knowledge of scientific terms like "acid," "base," "electron," and "molecule" are assumed. From the candy-colored cover to the index separated by lettered M&M's, eye-appeal abounds. Photographs of candy and experiments are well done although some experiments need more of them for clarity. Both topic and presentation will attract kids with a sweet tooth, but the book is not a necessary addition.-Carol S. Surges, formerly at Longfellow Middle School, Wauwatosa, WI
