Chemical Demonstrations, Volume 4: A Handbook for Teachers of Chemistry

The demonstrations capture interest, teach, inform, fascinate, amaze, and perhaps, most importantly, involve students in chemistry. Nowhere else will you find books that answer, "How come it happens? . . . Is it safe? . . . What do I do with all the stuff when the demo is over?"

Shakhashiri and his collaborators offer 282 chemical demonstrations arranged in 11 chapters. Each demonstration includes seven sections: a brief summary, a materials list, a step-by-step account of procedures to be used, an explanation of the hazards involved, information on how to store or dispose of the chemicals used, a discussion of the phenomena displayed and principles illustrated by the demonstration, and a list of references. You'll find safety emphasized throughout the book in each demonstration.

“The mostcomprehensive set of chemical demonstrations handbooks ever created.”—Roald Hoffmann, Nobel Laureate in Chemistry

"WOW! . . . HOW?" your students will exclaim when you present the demonstrations in the acclaimed Chemical Demonstrations Volumes 1–4.

As the U.S. Latino population grows rapidly, and as the LGBTQ Latino community becomes more visible and a more crucial part of our literary and artistic heritage, there is an increasing demand for literature that successfully highlights these diverse lives. Edited by Lazaro Lima and Felice Picano, Ambientes is a revolutionary collection of fiction featuring stories by established authors as well as emerging voices that present a collective portrait of gay, lesbian, bisexual, and transgender experience in America today. With a preface by Picano and an introduction by Lima that sets the stage for understanding Latino literary and cultural history, this is the first anthology to cross cultural and regional borders by offering a wide variety of urban, rural, East Coast, West Coast, and midwestern perspectives on Latina and Latino queers from different walks of life. Stories range from sensual pieces to comical romances and from inner-city dramas fueled by street language to portraits of gay domesticity, making this a much-needed collection for many different kinds of readers. The stories in this collection reflect a vibrant and creative community and redefine received notions of gay and lesbian.

Color and light are the focus of this long-awaited fifth volume in the Chemical Demonstrations series, which describes demonstrations that effectively communicate science to both students and general audiences. Using full-color illustrations, the book provides meticulous instructions for safely demonstrating colorful phenomena and illustrating scientific principles. A rich introductory section explores the science of color and light, outlines the chemical processes of vision, and explains what happens when visual information enters the human eye and is perceived by the brain. With more than fifty demonstrations and multiple procedures included, this volume offers abundant opportunities to arouse and sustain interest in science for both classroom and public presentations. \n
