|Environmental Science: 49 Science Fair Projects —
Robert L. Bonnet
Published by TAB Books/McGraw Hill, 1990.
How does a tree recycle itself? Can you make your own topsoil? And how can you tell if the air inside your house is polluted? You'll find the answers to such questions as you explore the environment with these science projects. The book begins with a discussion of scientific methods, tips on competing in a science fair, and hints for choosing the right project. The topics include recycling, waste management, pest control, microorganisms, habitats, and life cycles. Each of the 49 projects contains an overview, a list of materials needed, easy-to-follow procedures, and suggestions for experimenting further. Black-and-white drawings illustrate some of the steps.
