Two "Gas-in-a-Bag" Reactions To Show the Predictive Power of the Relative AcidBase Strength Chart Brett Criswell Describes a demonstration in which two different pairs of solid chemicals mixed in two different Ziploc bags in the presence of a small quantities of water react to produce gases. Students are informed that the reactions are BrnstedLowry acidbase type reactions and must determine which member in each pair will act as the acid and which as the base. Criswell, Brett. J. Chem. Educ. 2006, 83, 1167.

The Virtual ChemLab Project: A Realistic and Sophisticated Simulation of Organic Synthesis and Organic Qualitative Analysis Brian F. Woodfield, Merritt B. Andrus, Gregory L. Waddoups, Melissa S. Moore, Richard Swan, Rob Allen, Greg Bodily, Tricia Andersen, Jordan Miller, Bryon Simmons, and Richard Stanger Describes a set of sophisticated and realistic laboratory simulations for use in freshman- and sophomore-level chemistry classes and laboratories called Virtual ChemLab. The purpose of these simulations is to reinforce concepts taught in the classroom, provide an environment for creative learning, and emphasize the thinking behind instructional laboratory experiments. Woodfield, Brian F.; Andrus, Merritt B.; Waddoups, Gregory L.; Moore, Melissa S.; Swan, Richard; Allen, Rob; Bodily, Greg; Andersen, Tricia; Miller, Jordan; Simmons, Bryon; Stanger, Richard. J. Chem.

The Addition of Bromine to 1,2-Diphenylethene Judith C. Amburgey-Peters and LeRoy W. Haynes We investigated the reaction of (Z)-1,2-diphenylethene (cis-stilbene) with various brominating reagents and solvents following directions in standard organic chemistry manuals. We were particularly interested in learning which combination of brominating reagent and solvent gave the best yield of (d,l)-1,2-dibromo-1,2-diphenylethane without the formation of significant amounts of meso-1,2-dibromo-1,2-diphenylethane, which is essentially the sole product from the reaction of bromine with (E)-1,2-diphenylethene (trans-stilbene). Based on the results from the standard preparatory methods, some permutations of solvent and brominating reagent were tried. Amburgey-Peters, Judith C.; Haynes, LeRoy W. J. Chem.

Teaching about Flame Retardants. A Joint Israeli-Dutch Project Miri Kesner and Wobbe de Vos Flame retardants make interesting chemistry and moreover, the chemistry is highly relevant from an everyday life point of view. This article reports on a joint Israeli-Dutch project aimed at teaching the production, properties, and applications of some bromine-containing flame retardants, including their environmental aspects, in secondary education.
