Adventures with Atoms and Molecules

School Library Journal

Gr 5-8 Like the authors' Adventures with Atoms and Molecules (Enslow, 1985), this volume of experiments further introduces chemistry to upper elementary readers. There are 30 new experiments, each followed by one or more ideas to investigate. The experiments present many scientific principles through the safe use of ingredients found around the house. Safety is a prime consideration. Cautionary statements are printed in boldface type. The acids are weak, such as lemon juice and vinegar, and the strongest base is a solution of calcium hydroxide purchased in the grocery store as ``pickling lime.'' The format matches that of the first volume. The experiments are illustrated with computer-generated black-and-white drawings. It is rare to find a book that illustrates the principles of chemistry as clearly and with as much enthusiasm as this. All libraries serving children will want to have this book and its predecessor; school libraries will want to order additional copies for teachers' collections. Margaret H.

How does heat affect wrinkles in clothing? Can freezing temperatures harm plants? The fifth volume in this hands-on Adventures with Science series contains 30 experiments that demonstrate basic chemistry principles. For each experiment there's a list of materials, an outline of procedures, questions about observations, detailed discussion of the results, and suggestions for other things to try. Where necessary, there are strong safety directives about asking an adult for help. The book looks like a basic user's guide with small type, clear subheads, and occasional black-and-white illustrations. The writing style is plain and direct, just right for the stated purpose of making young people do, observe, and think science. There are lots of starters here for science fair projects.
