Reviews recent literature from science education publications and discusses their implications for chemistry education. (DKM)

Presents examples of various kinds of chemical misinformation culled from newspapers and magazines. Excerpts vary from the comic to the tragic--some errors are conceptual and others are quantitative. Appropriate questions and answers are included. (DKM)

Describes a convenient method of preparing chlorine water by mixing hydrochloric acid with sodium hypochlorite. (DKM)

Describes the Science on Wheels program developed by the chemistry department at the University of Puerto Rico at Mayaguez (UPRM). The program combines science demonstrations with grade 7-12 science teacher training in a mobile unit that transfers resources from the UPRM campus to schools around the island. Contains 39 references. (DKM)

Describes a demonstration on the density of the liquids water and ethanol and the solubility of air in those liquids. Also includes a related demonstration using Styrofoam balls. (DKM)

Describes a demonstration in which liquid ammonia is used to shrink paper items such as an American dollar bill with no change in mass. (DKM)

Presents a critical review of numerous papers related to the balancing of oxidation-reduction equations. Contains 53 references. (DKM)

Describes a systematic method for balancing both simple and complex chemical equations. (DKM)

Describes a systematic method for balancing all types of redox equations. The method employs the use of linked sets and includes the rules for balancing complex equations. (DKM)

Describes the methods used to balance three specific complex redox equations which were previously alleged to be unsolvable. (DKM)

Presents an algebraic method for balancing complex oxidation-reduction equations. (DKM)

Shows how the computer software programs Mathematica and Maple can be used to obtain chemical equations to represent the stoichiometry of a reacting system. Specific examples are included. Contains 10 references. (DKM)

Argues that acceptance then management of collective knowledge is increasingly important and that individual understanding and views toward the world are less valued. Considers the implications of this perspective for chemistry instruction. (DDR)

Argues that patterns of student flow between two- and four-year institutions are not linear and that the permutations of student situations affect the datasets that are used to both defend and question the effectiveness and transferability of two-year programs. (DDR)

Provides details on the chemical composition of trees including a definition of wood. Also includes an activity on anthocyanins as well as a discussion of the resistance of wood to solvents and chemicals. Lists interesting products from trees. (DDR)
