Optimizing the Use of Personal Response Devices (Clickers) in Large-Enrollment Introductory Courses  Klaus Woelk
This taxonomy of clickerselectronic devices with which students can remotely submit responses to questions posed by a teacherclassifies their use into two general categories. The first involves probing class attendance, preparedness, and subject matter interest, while the second pertains to the enhancement of conceptual understanding and content mastery.

Greener Alternative to Qualitative Analysis for Cations without H2S and Other Sulfur-Containing Compounds  Indu Tucker Sidhwani and Sushmita Chowdhury
The classic technique for the qualitative analysis of inorganic salts and mixtures relies on highly toxic hydrogen sulfide. Increasing environmental awareness has prompted the development of a green scheme for the detection of cations by spot tests that is simple and fast.

Fluorescence Spectroscopy in a Shoebox  M. Farooq Wahab
Concepts related to fluorescence spectroscopy are demonstrated with a simple fluorometer that examines highlighter ink using a flashlight or the sun as a light source, a bowl of water with a mirror as the dispersing element, colored cellophane as filters, and the human eye as a detector. In addition, a spectrofluorometer is constructed using gratings made from a DVD or CD.

Fractional Distillation of Air and Other Demonstrations with Condensed Gases  Maria Oliver-Hoyo and William L. Switzer, III
This demonstration builds upon the commonly performed liquefaction of air not only to show the presence of nitrogen and oxygen, but also the presence of two other components, carbon dioxide and water. Several extensions are suggested: one to show boiling point elevation in solution and another to show the elevation of both boiling point and sublimation point with pressure. No special apparatus is required permitting presentations to audiences in a variety of settings. These demonstrations give the opportunity to discuss properties of gases, solution chemistry, and phase equilibria.

A Substitute for “Bromine in Carbon Tetrachloride”  Joshua M. Daley and Robert G. Landolt
Benzotrifluoride (BTF) is a suitable solvent substitute for carbon tetrachloride in experiments requiring application of bromine (Br2) in free radical or addition reactions with organic substrates. A 1 M solution of Br2 in BTF may be used to distinguish hydrocarbons based on the ease of abstraction of hydrogen atoms in thermally or light-induced free radical substitutions. Efficacy of minimization of solvent use, by aliquot addition to neat samples, has been established.
