"Titles in Barron's extensive Painless Series cover a wide range of subjects as they are taught on middle school and high school levels. These books are written for students who find the subjects unusually difficult and confusing--or in many cases, just plain boring. Barron's Painless Series authors' main goal is to clear up students' confusion and perk up their interest by emphasizing the intriguing and often exciting ways in which they can put each subject to practical use. Most of these books take a light-hearted approach to their subjects, often employing humor, and always presenting fun-learning exercises that include puzzles, games, and challenging "Brain Tickler" problems to solve. This title clarifies the logic of the Periodic Table, explores atomic theory, chemical bonding, the structure of molecules, and more"-- "This book covers the subject of chemistry as taught to students in middle-school, including topics such as Matter, the Periodic Table of Elements, Phases of Matter, Gas Laws, Mixtures, Molecules and Compounds, Chemical Reactions, Acids, Bases, and Salts, Nuclear Reactions, and Environmental Science. There are short quizzes throughout the book. Contains an index"--

From the Publisher: Green Technology is an eight-volume set that examines the relationship between human activities and their sometimes harmful consequences for the environment and explores new methods of repairing and restoring the Earth. Approaching environmental issues confronting society from a technological perspective has spawned significant controversy, and the books in this set present all sides of the debate. Designed to complement science curricula, the set also covers relevant history and new green technologies and innovations that will contribute to the field in the future. Environmental Engineering: Designing a Sustainable Future examines how this field, which incorporates not only aspects of art and design but also physics, geology, ecology, and the chemistry of matter, evolved from a discipline of civil engineering. Environmental engineers learn how to work with nature to improve and control the quality of the land, air, and water for the benefit of human and nonhuman cohabitation. Sidebars, figures, and case studies enhance fundamental concepts and examine urgent issues related to the "natural future" of the environment. The volume includes information on: aerodynamics; ecological and energy "architecture"; energy-efficient electronics; innovations in personal vehicles; landscape design; micro climates; solar homes; sustainable manufacturing; transit systems; and wastewater. The book contains 50 color photographs and line illustrations, five appendixes, a glossary, a detailed list of print and Internet resources, and an index. Green Technology is essential for high school students, teachers, and general readers who seek information on the important issues that affect the environment worldwide.
