Presented in English and French, Chemistry 20-30 is an academic program that helps students in Alberta, Canada, better understand and apply fundamental concepts and skills. The major goals of the program are: (1) to develop in students an understanding of the interconnecting ideas and principles that transcend and unify the natural science disciplines; (2) to provide students with an enhanced understanding of the scientific world view, inquiry, and enterprise; (3) to help students attain the level of scientific awareness essential for all citizens in a scientifically literate society; (4) to help students make informed decisions about further studies and careers in science; and (5) to provide students with opportunities for acquiring knowledge, skills, and attitudes that contribute to personal development. This booklet includes information on general and specific learner expectations and units on: matter as solutions, acids, bases and gases; quantitative relationships in chemical changes; chemical bonding in matter; thermochemical changes; electrochemical changes; and equilibrium, acids, and bases in chemical changes. Each unit outlines the major concepts and the understanding, skills, and interrelationships among science, technology, and society that students should be able to demonstrate. (JRH)

Recommends integrating different applications to serve the need for students to know the relevancy of the course of their future. Uses different and unrelated phenomena to teach equilibria. Introduces six phenomena; (1) Killer Lakes of Cameroon, (2) Chicken Breath, (3) The Permian Ocean, (4) Snow Line, (5) Hard-Water Boiler Scale, and (6) Stalactites and Stalagmites. (YDS)

Illustrates how a novel problem of chemical equilibrium based on a closely related sequence of items can facilitate students' conceptual understanding. Students were presented with a chemical reaction in equilibrium to which a reactant was added as an external effect. Three studies were conducted to assess alternative conceptions. (Author/SAH)

Describes the different types of scientific calculators and explains how graphic calculators can apply to chemical problems. (Contains 19 references.) (YDS)

Presented are the teacher's guide and student materials for one of a series of self-instructional, computer-based learning modules for an introductory, undergraduate chemistry course. The student module for this introductory unit on chemical equilibrium includes objectives, prerequisites, pretest, instructions for executing the computer program, and problems. Included in the teacher's guide are implementation instructions, software, sample run, and listings of the computer program in both BASIC and FORTRAN. (BT)

Presented are the teacher's guide and student materials for one of a series of self-instructional, computer-based learning modules for an introductory, undergraduate chemistry course. The student manual for this acid-base equilibria unit includes objectives, prerequisites, pretest, a discussion of equilibrium constants, and 20 problem sets. Included in the teacher's guide are implementation instructions, answers to problem sets, software, a listing of the computer program in BASIC, and 10 unit tests. (BT)

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. (TW)

Presents a simple qualitative system for sketching all manner of acid-base titration curves, requiring only the approximate values of the acid or base ionization constants. (WRM)

Discusses the furnace from a chemical thermodynamics perspective. Examines the enthalpy, entropy, and free energy change for each reaction of importance. These properties are interpreted on the molecular level then used to deduce the conditions necessary for each reaction to occur in its intended direction. Chemical kinetics is also discussed. (DKM)

This unit of instruction deals with the study of both physical and chemical systems in equilibrium. It provides the student with instruction that will enable him to predict products in solubility, acid-base, and oxidation-reduction reactions and to write and balance equations for these reactions and solve problems involving equilibria constants. Students will gain more from this course if they have had some previous work in energy concept of atoms and molecules. The booklet lists the relevant state-adopted texts and states the performance objectives for the unit. It provides a course outline; suggests experiments, demonstrations, projects, reports, speakers, and field trips; and presents a series of related mathematical problems. Films, film loops, filmstrips, and several reference books are recommended. A master sheet is provided relating each suggested activity to the specific performance objectives. (EB)

Presents a simulation that helps students understand the concepts of equilibrium and Le Chatelier's principle. (JRH)

Describes a computer program that can model the equilibrium processes in the production of ammonia from hydrogen and nitrogen, sulfur trioxide from sulfur dioxide and oxygen, and the nitrogen dioxide-dinitrogen tetroxide equilibrium. Provides information about downloading the program ChemEquilibrium from the World Wide Web. (JRH)

ChemSource is designed as a strategy to help preservice and inservice high school chemistry teachers promote student learning more effectively. Its major premise is that well-designed laboratory investigations are an important avenue for cultivating student interest, engagement, and meaningful learning in chemistry. The SourceBook component of ChemSource is a resource containing 36 content modules and additional supporting materials which aim at providing specific teaching tips and the best available instructional ideas and information gleaned from experienced, successful chemistry teachers. Each content module features: Content-in-a-Nutshell; Laboratory Activities; Demonstrations; Common Misconceptions; Humor; Applications and Implications; Analogies; Reference Resources; History; and Media. General materials on pedagogy, classroom management, safety, teaching chemistry to the disabled, and other useful resources and tabulations precede and follow the content modules. Volume 2 includes the following: Chemical Equilibrium; Food and Chemistry; Forensic Chemistry; Gases; Molecular Geometry; Halogens; Industrial Inorganic Chemistry; Instrumentation; Materials Science: Ceramics and Glasses; Chemistry in Medicine; and The Mole.
