Environmental Science Fair Projects, Using the Scientific Method

* Reviews *

One of a series of science projects based upon earth science concepts, this revised and expanded edition contains eighteen experiments or science fair projects for the young scientist. The introduction gives a brief description of environmental concerns, a detailed explanation of the scientific method, how to design an experiment, the importance of recording data, and tips on developing a successful science fair project. Two pages about safety help the student and parent conduct the experiment in the safest possible way and properly dispose of any materials used. The projects are divided into five basic sections of environmental science, each with a brief description of its environmental importance. The first section, air, contains experiments on oxygen, from photosynthesis to the greenhouse effect. Next topic is water, with investigations on the water cycle, acid rain, and algal blooms. The third section, soil, looks at the types of soil, acidity of the soil, and erosion. Part 4 focuses on pollution and its affect on plants, materials, and air quality. The final section provides the reader with projects based upon energy resources and the development and use of renewable and sustainable ways to generate energy from the sun, wind, and decomposing matter. 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
