Gives a brief account of fluoropolymers as an important part of polymer chemistry and attempts to make the topic relevant to the secondary school audience. Provides general characteristics and applications for fluoropolymers. (MVL)

Introduces the Chemical Education for Public Understanding Program (CEPUP), a program concerned with chemicals and their uses. Describes the origins, material development, modules, and dissemination of the program. (Author/YP)

Describes a program in chemistry which was designed to encourage undergraduate minority students to enroll in graduate study. States that students attended meetings with their advisors and met as a group for a research lecture. The program included graduate students, staff, and professors who gave lectures and tours. (RT)

Describes a research program that has active areas of research ranging from hydrology, water chemistry, geology, gene cloning, satellite image analysis and remote sensing, and molecular biology. Provides information on selection procedures, design of program, benefits, and names of participants. (RT)

Introduces an interdisciplinary activity using a cola drink. Describes the lesson plan, including objectives, procedures, evaluation, projects, and conclusions. Provides two laboratory sheets containing problem, hypothesis, materials, procedure, observations, and conclusions, vocabulary table, and data table. (YP)

Describes a method for demonstrating absorption spectra of intensely colored solutions using a mounted grating and a specially designed cell. Allows a student to compare the spectrum of a white light source directly with the same light modified by an absorbing spectrum. Uses acrylic tubing to make the cell. (MVL)

Describes two experiments designed to provide concepts on the difference between heat and temperature and also bond energy. Investigates both a neutralization experiment and a ligation experiment. Notes inexpensive chemicals are used along with simple equipment. Discusses the sharing of lab results for a single class value. (MVL)

Describes 36 science activities. Topics include: osmosis, fermentation, anhydrobiotic organisms, breathing monitors, trypsin, weeds, amyloplasts, electrolysis, polarimeters, ethene ripening of fruit, colorimetry, diffusion, redox reactions, equilibria, acid-base relationships, electricity, power, resonance, measurement, parallax, amplifiers,…

Describes a college program of research collaboration with high school teachers and an academic alliance that emerged from the experiences. The background, organization, achievements, and reluctance factors related to the program are discussed. (YP)

Describes an undergraduate biochemistry laboratory experiment on enzyme kinetics using the D-amino acid oxidase system and an ammonia electrode. Preparation of an ammonia standard curve, a sample preparation, and inhibition studies are discussed. (YP)

Discussed are the ways that misconceptions about chemistry are acquired by presecondary children. Several recommendations for teaching chemistry to children are presented including the use of variety, hands-on experiences, critical thinking skills, and appropriate timing of concepts. (CW)

Described is a capstone experiment which can be used to improve student skills and to illustrate for students the strong connections between chemistry and biology. Procedures and explanations for the three parts of this activity are included. Ten follow-up questions are provided. (CW)

Described are some of the difficulties presented in these reactions by competing equilibria that are usually ignored. Situations involving acid-base equilibria, solubility product calculations, the use of ammonia as a complexing agent, and semiquantitative comparisons of solubility product values are discussed. (CW)

Discussed are the deficiencies of teaching laboratories in science education and the feasibility study and development of the Institute for Teaching Experimental Chemistry at Carnegie Mellon University. The primary goals of the program and its significant elements are presented. (CW)

Presented are gravimetric and volumetric procedures which may be used by students to measure the zinc coating on steel. Listed are materials, methods, calculations, and discussion questions. (CW)
