ADVENTURES WITH ATOMS AND MOLECULES, BOOK II: More Chemistry Experiments for Young People

Thirty home chemistry experiments for middle-grade children that may prove problematic--the experiments presented do not verify or disprove the question asked, and the index is inadequate. Each easy experiment begins with a question, followed by a list of materials, procedure, observations, discussion, and other things to try. A safety note is included. In ""Can water act like glue?,"" the experimenter puts water on two sheets of paper and notes the adhesion that is attributed to the strong polarity of water molecules. Paper molecules are also polar, according to the discussion, but do not strongly attract each other when dry. Why not? No reason is given. In several experiments, additional variables are introduced that obscure the results. In ""Can molecules in the air cause colors to fade?,"" the experiment really demonstrates how sunlight fades. The index lists vinegar, whey, and other materials used in experiments, but provides no access concepts, such as experiments dealing with polar molecules.
