Environmental Science: High-School Science Fair Experiments Book

A great resource for students in grades 10-12 who are entering science fair competitions, Environmental Science contains 22 thought-provoking projects that teach the scientific method and analytical thought through hands-on experiments. For each experiment, H. Steven Dashefsky includes in-depth background information, an overview, a materials list, step-by-step procedures and alternative methods, an estimate of how much time it will take to complete the experiment, procedures for analyzing the data, helpful illustrations, suggestions for going further, and extensive bibliographic references. Dashefsky covers a broad range of environmental concerns in these practical experiments, including ecosystems, energy flow, recycling and waste reduction, pesticides, global warming and the greenhouse effect, ozone depletion, smog (causes and effects), soil ecosystems, soil erosion, aquatic ecosystems, water pollution, food additives and other contaminants, sustainable agriculture, indoor pollution, deforestation and desertification, fossil fuels, and alternative energy sources (wind, water, and solar energy).
