Teaching Avogadro's Hypothesis and Helping Students to See the World Differently  Brett Criswell
This article uses a model from educational psychologyChi's theory of ontological misclassificationto explain the source of students' difficulties in understanding Avogadro's hypothesis and provide a method to successfully teach this fundamental concept.

Exception to the Le Châtelier Principle  Thomas R. Herrinton
Disagreement regarding an apparent exception to the Le Chtelier principle involving the effects of nonideality on the direction in which the ammonia synthesis reaction shifts upon addition of infinitesimal and finite quantities of nitrogen at constant pressure and temperature.

Job's Analysis of the Range of the "Dalton Syringe Rocket"  Natalie Barto, Brandon Henrie, and Ed Vitz
An apparatus for safely igniting fuel gas/oxygen mixtures in a syringe and measuring the distance that the syringe is propelled is presented. The distance (range) is analyzed by the method of continuous variation (Job's Method) to determine the stoichiometry of the reaction.

A Note on Dalton's Law: Myths, Facts, and Implementation  Ronald W. Missen and William R. Smith
The treatment of Dalton's law for gas mixtures commonly includes the improper designation "Dalton's law of partial pressures", rather than the correct "Dalton's law of additivity of (pure component) pressures". It also identifies the pure component pressure as the partial pressure, although these are only numerically equal for a mixture of ideal gases. The situation is clarified by examination of an appropriate statement of the law and definitions, eventually in operational form with reference to mixtures of nonideal gases.

Does a one-molecule gas obey Boyle's law?  Rhodes, Gail
Because the kinetic molecular theory provides a plausible explanation for the lawful behavior of gases, it should be treated in enough depth to show students that the theory accounts for all of the important aspects of ideal gas behavior.
