Discusses how a chemistry teacher can help the student learn the technical vocabulary of chemistry. (MLH)

Discusses an explanation for secondary science students of the concept of additivity of oxidation and reduction potentials, especially in relation to the nonapplicability of Hess's Law. (MLH)

Discusses a comparison of the relative effects on the stomach of a strong acid, hydrochloric acid, and a weak acid, aspirin. Also discusses molecular geometrics using the Valence Shell Electron Repulsion Theory. (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 a laboratory experiment in which uranium is isolated by the reduction of uranyl acetate. (MLH)

Describes the development of a student-centered chemistry program, based upon the Interdisciplinary Approaches to Chemistry (IAC), designed for two kinds of students: those who are science-oriented and mathematically inclined and those who are not inclined towards mathematics and find theoretical discussions difficult. (Author/SA)

This freshman chemistry lab relates stoichiometric problems to real situations. It requires students to measure the Fe impurity in reagent grade calcium chloride. (BB)

An outline is given for a lesson on gases for high school students. Solutions are given; however, requests are made for alternative solutions. (SA)

A reasoning test was administered by all science teachers at a high school. This report presents the results of the test and explains how this information can be used to improve teaching. (BB)

A discussion is presented on what should be taught about orbitals in high school chemistry. (BB)

Describes a high school chemistry experiment which involves the reaction between calcite and hydrochloric and sulfuric acids. This reaction can be carried out as a projected demonstration and on an individual basis. (HM)

This column for high school teachers, written by high school teachers, discusses several interesting anecdotes related to the formulation of laws and the determination of constants. Science history is presented in a manner that can enliven classroom presentations and aid in understanding the principle itself. (Authur/SA)

Tries to clarify some apparent confusion surrounding the concept of atomic weights as presented in some chemistry textbooks. Another confusion is with the word thermometer, as it implies heat measurement. Suggests renaming it calorikinetic potentiometer, instead, to reflect what it does. (GA)

A discussion of problems students have with the concept of percent, with special emphasis on the use of percent in elementary chemistry. (BB)

Presents a formulations laboratory project in which secondary school students attempt to prepare a common household product from laboratory chemicals. (HM)
