Describes the effect of "plant growth regulators" on plants, such as controlling the flowering, fruit development, plant size, and increasing crop yields. Provides a list of plant growth regulators which includes their chemical, common, and trade names, as well as their different use(s). (GA)

Describes a portion of a chemistry-oriented science course, the toxicology of the metal thallium, in the context of literature and related sources. (GA)

A practical exercise is described that allows students to investigate a specific problem using a variety of biochemical techniques. The need for a thorough understanding of the theoretical principles underlying these processes is emphasized. A program of private study and assessment is suggested to enable the progress of students to be followed.…

Describes a laboratory experiment demonstrating the aldehyde oxidase activity in wild type and mutant fruit flies using a quantitative assay. The experiment can be performed in one hour. (MA)

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)

Introduces an approach to teaching amino acids that employs the use of a poem containing information on the structure and properties of amino acids, and of slides illustrating the poem. Student response to the method was positive. (MA)
