Describes a community chemistry course for children aged 10-13 which emphasizes the recording of experimental observations in lab notebooks and the use of experiments that require few directions. (MLH)

Describes an advanced undergraduate experiment in which the stepwise stability constants of hi(II)-cysteine chelate are determined. (MLH)

Describes an experiment in which the technique of ph-controlled extractive separation is used to separate a mixture of drugs aspirin (acidic), caffeine (basic), and phenacetin (neutral). (MLH)

Describes an experiment in which ph values serve as a basis for separating the acidic aspirin from phenacetin and caffeine on an ion-exchange column. (MLH)

Presents a manual of safe laboratory practices and precautions, covering such things as fire, explosion, poisoning, and injuries. (MLH)

Presents a table of events that lists chronologically, in parallel columns, major occurrences in the histories of both the United States and science, as well as the names of individuals normally associated with an event or period. (MLH)

Discusses the prominent American chemists of the nineteenth century and the way in which contemporary European science influenced them. (MLH)

Describes a computer program that allows the numerical solution of an acid-base equilibrium polynomial equation without the need for chemical approximations. (MLH)

Discusses the use of additive and substitutive nomenclature for chemical substances rather than classifying substances as organic or inorganic. (MLH)

Presents demonstrations concerning the thermodynamic properties of rubber elasticity and simultaneous reactions of acetone. (MLH)

Presents questions and answers about various chemical topics such as the supply of fossil fuels, mercury contamination of water, and lead and nitrous oxides emissions from gasoline. (MLH)

Describes a card game that uses chemical symbol and number cards to represent chemical formulas. Also discusses an end-of-term review game that utilizes competing teams. (MLH)

Discusses the fact that heat only exists at the boundary of a system as energy is being transferred because of a temperature difference between the system and the surroundings. Points out that many texts incorrectly refer to heat as a system component. (MLH)

Describes the licensing procedures for chemists in the Philippines, and presents a picture of how the Licensing Law has affected the status of Philippine professional chemists and chemical technicians. (MLH)

Discusses the special aspects of chemical higher education programs in Africa, the influence of government in African universities, and university research programs and facilities. (MLH)
