Describes a chemistry course designed for the general student at Pampa Senior High School, Pampa, Texas. It presents the fundamental concepts in chemistry in a nonmathematical context; contains many options in the form of minicourses; and permits the student to pace himself. (HM)

Describes an exercise that illustrates the synthesis of an amino acid and Michael type condensation. The exercise can be used with college students of chemistry or biochemistry. (HM)

Describes a computer model kinetic theory experiment for the college physical chemistry laboratory. (HM)

Presents an undergraduate physical chemistry laboratory experiment describing the measurement of the proton magnetic resonance spectra. (HM)

Describes an experiment that has been introduced in the organic chemistry laboratory program at Shepherd College, Shepherdstown, West Virginia. It illustrates microbial reaction and its role in the synthesis of vitamin C. (HM)

Presents a biochemistry experiment for college students that illustrates the purification of an enzyme. (HM)

Describes an advanced analytical chemistry laboratory experiment developed for the determination of the performance parameters of a spectrophotometer. Among the parameters are the baseline linearity with wavelength, wavelength accuracy and respectability, stray light, noise level and pen response time. (HM)

Describes a college student chemistry laboratory experiment that illustrates the construction of a polarimeter from inexpensive, readily-available materials. (HM)

Reports the chemistry of saxitoxin, a paralytic shellfish poison, and other toxins, including the structure of aplysiatoxins. Discusses the chemical signals and defense agents used in intra- and inter- species communication; anticancer agents; and organometallics in the marine environment. (MA)

Deals with Piaget's research and theory over the past five decades. The purpose of the paper is to identify important aspects of Piaget's work and to refer the reader to sources readily available in books and periodicals. These are outlined in the annotated bibliography at the end of the paper. (Author/MA)

It has been discovered that dreams and daydreams can be productive states in the process of scientific innovation. An attempt is made to provide some typical examples of insights which have come to scientists during dream-like states and in sleep. (Author/MA)

Reports that energy required to promote a 4f electron to the 5d level has a profound and predictable influence on the systematics of reactions involving conversion of rare earth atoms from combined to free states. (Author/MA)

Examines an alternative approach to analysis of chemical reactions. In this approach, a thermal entropy gradient is introduced. (MA)

The nature of bonding in magnesocene is currently in dispute. This paper presents a brief review of the structure and bonding proposed for magnesocene, leading up to the most recent work. (Author/MA)

Describes a study done to compare the cognitive preferences of four student populations: postgraduate students in chemistry, students from academic high schools, those in vocational schools training to become lab technicians, and students joining science clubs. Results of a 34 item cognitive preference test are summarized. (Author/MA)
