Water Science Fair Projects, Using the Scientific Method

* Reviews *

One in a series of Chemistry Science Fair Projects by the publisher, this reviewed and revised text offers twenty-four experiments that can be used in conjunction with a middle school science fair project. Starting with a brief introduction about the importance of water, the author leads the reader through a detailed description of the scientific method, how to design an experiment, record data, and tips on how to be successful in your project. Two pages are devoted to the use of proper safety techniques and the correct methods for disposing of the materials used. The first section deals with the structure of water and provides experiments on molecular structure and solubility. The next section addresses the three states of matter and examines why ice cubes float, how changing from solid to liquid requires heat energy, and the process of distillation. Section 3 looks at surface tension, adhesion, and cohesion and includes experiments using soap bubbles and capillarity. The last set of experiments focuses on the chemical properties of water, how it is involved in certain reactions, acids, bases, and indicators, and testing for water quality. Each experiment has an informative introduction, detailed procedure, and a results and conclusion section. Further ideas to expand the concept and experiment are included, and a glossary and research pages provide further information for the young scientist., Children's Literature
