DESCRIPTORS Chemical Bonding; Chemical Equilibrium; *Chemical Reactions; *Chemistry; *College Science; *Demonstrations (Educational); Energy; Nigher Education; Kinetics; Oxidation; *Science Activities; Science Education; Science Instruction; Secondary Education; *Secondary School Science ABSTRACT This book contains 112 classroom demonstrations intended to be used with any introductory chemistry program. These demonstrations were selected in an effort to provide simple, safe, effective and enjoyable experiences for the class. In addition, they are intended to be used to introduce many of the major concepts in chemistry. The demonstrations involve color changes, gas evolution, precipitate formation, smoke, fire, and other obvious or dramatic chemical changes. The guide is organized into 11 major sections including: (1) introducing chemistry; (2) physical changes; (3) reactions involving gases; (4) reactions of some elements; (5) transition metals and complex ions; (6) chemical bonding; (7) energy changes; (8) solutions and solubility; (9) kinetics and equilibrium; (10) acids and bases; and (11) oxidation and reduction reactions. Appendices include an equipment and reagent list and detailed safety and disposal instructions.

PRINTED IN THE UNITED STATES OF AMERICA 3 About the Authors LEE R. SUMMERLIN received his B.A. in Chem- istry/Biology from Samford University, his M.S. in Biology/Chemistry from Birmingham- Southern College, and his Ph.D. in Chemistry/ Science Education from the University of Maryland. He has held many teaching and administrative positions as well as servedas a consultant to various agencies and organiza- tions, companies, colleges and universities, and school boards in this country and abroad. He has served as a peer review panelist for several science educational development programs andas a chemistry consultant to various National Science Foundation Institutes. He has presentedmany seminars and published a number of bookson methods and aspects of teaching chemistry and science. He has also con-!uctednumerous workshops on chemical demonstrations throughout the country. He servedas coordinator of the Institute for Chemical Educationprogram at the University of California Berkeley in the summer of 1986. Dr. Summerlinhas held office or had major committee assignments in the American ChemicalSociety, the National Science 'leachers Association, the AmericanAssociation for the Advancement of Science, the Florida Association of Science Teachers,and the Association for the Education of leachers of Science. Hewas the recipient of the American Chemical Society Outstanding Chemistry TeacherAward (1967), the James B. Conant Award (1969), and the Du Pont Award(1970). He received the 1985 Ingalls Award, which is given to the OutstandingTeacher at the University of Alabama at Birmingham, andwas a national recipient of the 1986 Chemical Manufacturers Association Catalyst Award. CHRISTIE BORGFORD received her B.S. from the University of Washington. She taught chemis- try and served as Science Department Chair- man at Washington High School, Washington, MO, and is now at Oregon Episcopal School in Portland, OR. She has also servedas a bio- chemist for the Department of Interior andas a consultant for the Oregon Museum ofSci- ence and Industry. Throughout her teaching career, she has emphasized the experimental approach to chemistry and has developed and used chemical demonstrations for junior high schoolstudents, chemistry students, and chemistry teacher educationprograms around the country. She is Program Director for Secondary Inservice Programs forthe Northwest Institute for Science Education at Portland State University.She was codirector of the Chemical Demonstrations Program for theInstitute for Chemical Education (LC.E.) program at the University ofCaliforniaBerkeley in 1985 and was director of the Laboratory Program in1986. She serves as a consultant in chemical education and has published articlesand booklets on chemistry and chemical education, includinga laboratory manual for the Berkeley LC.E. program. She is active in the American ChemicalSociety, where \ 4 she serves as Precollege Chairman and International Olympiad Regional Chairman for the local section, and Chairperson for the High School Day at the Northwest regional meeting, and serves on the National Task Force for Prehigh School Chemistry. JULIE B. EAtx received her B.A. from State University of New York at Buffalo and her M.S. from Northern Illinois University. She has taught chemistry, honors chemistry, and advanced-placement chemistry for 15 years in public and private education. She currently . teaches at Pottsgrove High School in Pennsyl- vania. In addition to teaching highly talented students in advanced-placement chemistry, Ealy has been very effective in developing special courses centered around chemical activities and demonstrations for science-shy students, including high-school dropouts. She has helped ccaduct advanced-placement chemistry workshops at several sites including the Hill School in Pennsylvania and has conducted other workshops in chemistry and chemical dem nstrations locally and throughout the country. She has presented papers and original chemical demonstrations at several regional and national conventions including CHEM Ed 85 at Monclair State College and CHEM Ed 86 at Montana State University. Ealy served as field editor for Chemical Demonstrations A Sourcebook for Teachers and also served on the American Re-Write Committee and Editorial Board for ALCHEM, the Alberta Chemistry Project. Ealy is active in several professional organizations, including the American Chemical Society. She did volunteer work with Subcommittee II of the ACS to select and edit questions for the Advanced Chemistry Examination. A Word of Caution Demonstrations can be fun, and they add excitement to the teaching of chemistry. However, this volume is intended for use by professional chemists and chemistry teachers. Even the simplest demonstration is potentially dangerous when performed by someone lacking the manipulative skills and knowledge of chemistry necessary to understand the reactions involved. Every, precaution must be taken to ensure the

This information is distributed solely for the purpose of pre dissemination public comment under applicable information quality guidelines. It has not been formally disseminated by the Agency for Toxic Substances and Disease Registry. It does not represent and should not be construed to represent any agency determination or policy. ***DRAFT FOR PUBLIC COMMENT*** 1,2-DIPHENYLHYDRAZINE iii FOREWORD This toxicological profile is prepared in accordance with guidelines developed by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA). The original guidelines were published in the Federal Register on April 17, 1987. Each profile will be revised and republished as necessary. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for these toxic substances described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a substance's toxicologic properties. Other pertinent literature is also presented, but is described in less detail than the key studies. The profile is not intended to be an exhaustive document; however, more comprehensive sources of specialty information are referenced. The focus of the profiles is on health and toxicologic information; therefore, each toxicological profile begins with a relevance to public health discussion which would allow a public health professional to make a real-time determination of whether the presence of a particular substance in the environment poses a potential threat to human health.

Matisoff, Chair The Kuki-Chin languages constitute one of the most important subgroups of the great Tibeto-Burman family. This dissertation attempts to reconstruct the sound system of the ancestor language, Proto-Kuki-Chin, by comparing the initial consonants, rhymes, and nominal tones of a large number of KC languages. This study of Proto-Kuki-Chin depends primarily on twelve languages: three from the Central Chin group: Mizo (aka Lushai), Hakha Lai, and Falam Lai; four from the Southem- Plains Chin group: Mindat Cho, Daai, Asho (aka Plains Chin), and Khumi; four from the Northern Chin group: Tedim (aka Tiddim), Paite, Thado-Kuki, and Sizang; and finally one from the Maraic group, namely Mara (aka Lakher). Chapter 1 introduces the Kuki-Chin speakers and their geographical locations, and traces the etymologies of the names Kuki and Chin.
