Presents a demonstration used to give meaning to the terms node, amplitude, wavelength, and quantization. (JRH)

Presents experiments involving the analysis of commercial products such as carbonated beverages and antacids that illustrate the principles of acid-base reactions and present interesting problems in stoichiometry for students. (JRH)

Describes the construction of a vernier scale made of chart paper that can be used to improve the readability of scales on burettes or graduated cylinders. (JRH)

Presents a description for an undergraduate course designed to ensure that all science students have access to basic abilities early enough to apply them in their major. Focuses on scientific writing, speaking, literature searching, career planning, and other valuable skills that can prepare students for upper-level courses and entry into the job…

Reports on the Ninth Annual Worcester Polytechnic Institute Conference on Chemical Education that focused on the incorporation of materials science into chemistry courses as examples of chemical phenomena and on the identification of what chemistry a college graduate should possess to work in the area of materials science. (JRH)

Reports on a study, Project REMODEL, that implemented and evaluated innovations in lecture, laboratory, and assessment for students in the introductory sequence for undergraduate chemistry. Results indicate that special sessions and conceptual exam questions can improve students' abilities to work successfully with both concepts and algorithms.…

Describes a chemistry outreach program where graduate student volunteers perform shows to excite high school students about science. Lists the experiments and demonstrations performed in the shows, and concludes that this outreach benefits both the high school student audience and the graduate student volunteers. Contains 21 references. (JRH)

Presents graphic examples that can help students visualize the dilution process when presented along with mathematical relationships. Discusses basic concepts and serial dilutions. (JRH)

Presents three examples that show how students can use traditional physics principles or laws for the purpose of understanding chemistry better. Examples include Coulomb's Law and melting points, the Faraday Constant, and the Rydberg Constant. Presents a list of some other traditional topics in a chemistry course that could be enhanced by the…

Summarizes four recent documents that identify what is deemed essential in chemistry at grades 8 and 12, including: Benchmarks for Science Literacy Project 2061; 1994 National Assessment of Educational Progress; National Science Education Standards; and Scope, Sequence, and Coordination of Secondary School Science. Identifies areas of agreement…

Describes a laboratory course that introduces students to chemistry using examples commonly encountered in the supermarket and on the dinner table. Acquaints students with simple chemical tasks that can be practiced at home, including the making of wine, ale, soap, cheese, and yogurt, and introduces them to the small-scale production of…

Describes a simple experimental arrangement that can be used to demonstrate important basic properties of the plasma state. (JRH)

Describes a process that can be used to illustrate a number of chemical principles including Le Chatelier's principle, redox chemistry, equilibria versus steady state situations, and solubility of species. (JRH)

Describes a combination of solutions that can be used in the study of kinetics using the iodine clock reaction. The combination slows down degradation of the prepared solutions and can be used successfully for several weeks. (JRH)

Describes a teaching program that shows how electrochemical principles can be conveyed by means of hands-on experiences of student-centered teaching experiments. Employs the readily available lead-acid cell and the simple aluminum-air cell. Discusses the batteries, equilibrium cell potential, performance comparison, current, electrode separation,…
