Dinan, Frank J. – Journal of College Science Teaching, 2006
This interrupted case study, developed for an honors seminar and a nonmajors chemistry course, is based on data taken from a series of published research articles. The case explores the unintended side effects of chemicals introduced into the environment, specifically organic compounds that can act as environmental estrogens. Students examine the…

Zanger, Murray; Moyna, Guillermo – Journal of Chemical Education, 2005
A study uses nuclear magnetic resonance (NMR) spectroscopy in a novel way to determine the isotopic ration between [to the tenth power]B and [to the eleventh power]B in sodium borohydride (NaBH4). The experiment provides an unusual and relatively simple means for undergraduate chemistry students to accurately measure the distribution of the two…

Bhattacharyya, Gautam; Bodner, George M. – Journal of Chemical Education, 2005
A study examined the way graduate students solved mechanism problems that were far removed from the simple systems in which mechanisms are traditionally presented. One aim is to probe the extent to which the students' experiences with the organic chemistry as undergraduates prepared them to solve mechanism problems they were likely to face as…

Ritacco, Hernan – Journal of Chemical Education, 2006
A simple, low-cost experiment to demonstrate the wetting dynamics of liquids on solid surfaces is described, where a "Web cam" is used to measure the expansion of the drop as a function of time. The advantage of a Web cam is its low cost, which permits an individual setup per student and the results obtained from the students with these devices…

Miles, William H.; Connell, Katelyn B. – Journal of Chemical Education, 2006
Synthetic sequences in the undergraduate organic chemistry laboratory illustrate important synthetic strategies, reagents, or experimental techniques, oftentimes resulting in the synthesis of commercially important compounds. A fragrance with a 'spicy, carnation, sweet, vanilla', named after carnations (Dianthus caryophllus), Methyl Diantillis is…

Landolt, R. G. – Journal of Chemical Education, 2006
The chemical information instruction and environmental science which is incorporated into a first-year organic chemistry laboratory is presented. The students are charged with devised search strategies, conducting online searches and limiting the project scope to ocean systems. The laboratory serves to provide for search strategy development…

Ibrahim, Sami A. – Journal of Chemical Education, 2005
Johann Wolfgang Dobereiner, in 1829, made the first significant attempt to reveal a relation between the properties of the chemical elements and their atomic weights. His groupings remain useful for providing reasonable estimates for the properties and the atomic weights of the trans-lawrencium elements.

Gonzalez, Gabriel; Martinez, Manuel – Journal of Chemical Education, 2005
The quantity of information available on Co(III)-pentaammine complexes to the undergraduate students is based on their dissociatively activated substitution processes. The advanced undergraduate set of experiments is presented that fill an important gap in the understanding of the differences taking place in the substitution mechanisms operating…

van Arnum, Susan D. – Journal of Chemical Education, 2005
A useful metrics system for the assessment of the environmental impact of chemical processes is utilized to illustrate several of the principles of green chemistry. The use of this metrics system in conjunction with laboratory experiments in green chemistry would provide for reinforcement in both the theory and practice of green chemistry.

Bopegedera, A. M. R. P. – Journal of Chemical Education, 2005
A report to maintain US dominance in the science by actively recruiting future chemists from the chemistry classroom is presented. The report showed that conducting career week on regular basis could help to prevent further erosion of US's "dominance in sciences".

Grove, Nathaniel; Bretz, Stacey Lowery – Journal of Chemical Education, 2005
An inquiry-based experiment on Sherlock Holmes adventure stories used to actively involve students in a series of laboratory experiments to prove the guilt of the accused murderer is presented. The result from such experiments showed that students were able to distinguish between sugar and possible poison.

Szalay, P. S.; Hunter, A. D.; Zeller, M. – Journal of Chemical Education, 2005
The benefits of integrating single crystal X-ray diffraction into the curricula of the disciplines of science such as chemistry, biology, biochemistry physics, and many more are addressed. The results showed that students were able to complete all report requirements with the aid of handouts and instructor inputs, and remote control of the…

Sequin, Margareta – Journal of Chemical Education, 2005
Exploration of the Chemistry of Plants is established as a part of the department offerings for nonmajor science students to fulfill their science general education requirement. Plant themes proved to be very suitable in capturing the interest of the nonmajor science students as an introduction to chemistry.

Pelter, Michael W.; McQuade, Jennifer – Journal of Chemical Education, 2005
The experiments that mimic the actual brewing process to explain the science to the nonscience majors is performed using malted barley as the source for both the starch and the amylase enzyme. The experiment introduces the concept of monitoring the progress of chemical reaction and was able to show the chemical breakdown of the starch to simple…
