Cardinal, Pascal; Greer, Brandon; Luong, Horace; Tyagunova, Yevgeniya – Journal of Chemical Education, 2012
Electrophilic aromatic substitution is a fundamental topic taught in the undergraduate organic chemistry curriculum. A multistep synthesis that includes a safer and greener method for the bromination of an aromatic ring than traditional bromination methods is described. This experiment is multifaceted and can be used to teach students about…

McCain, Daniel F.; Allgood, Ottie E.; Cox, Jacob T.; Falconi, Audrey E.; Kim, Michael J.; Shih, Wei-Yu – Journal of Chemical Education, 2012
Only a few pedagogical experiments have been published dealing specifically with the hydrophobic interaction though it plays a central role in biochemistry. A set of experiments is presented in which students partition a variety of colorful indicator dyes in biphasic water/organic solvent mixtures. Students monitor the partitioning visually and…

Richardson, Tim H.; Brittle, Stuart A. – Physics Education, 2012
This paper describes a set of experiments aimed at overcoming some of the difficulties experienced by students learning about the topics of moments of inertia and simple harmonic motion, both of which are often perceived to be complex topics amongst students during their first-year university courses. By combining both subjects in a discussion…

Luck, Linda A.; Blondo, Ryan M. – Journal of Chemical Education, 2012
Nonscience majors often believe that the concepts and techniques in chemistry have little relevance to someone outside the "ivy-covered walls of academia". The challenge for science instructors is to develop and implement lessons that present science in a way that will capture the interest of the nonscience major, while remaining rigorous enough…

Izadyar, Anahita; Kim, Yushin; Ward, Michelle M.; Amemiya, Shigeru – Journal of Chemical Education, 2012
The inexpensive and disposable electrode based on a double-polymer-modified pencil lead is proposed for upper-division undergraduate instrumental laboratories to enable the highly sensitive detection of perchlorate. Students fabricate and utilize their own electrodes in the 3-4 h laboratory session to learn important concepts and methods of…

Geiger, H. Cristina; Donohoe, James S. – Journal of Chemical Education, 2012
Green chemistry addresses environmental concerns associated with chemical processes and increases awareness of possible harmful effects of chemical reagents. Efficient reactions that eliminate or reduce the use of organic solvents or toxic reagents are increasingly available. A two-week experiment is reported that entails the calcium hypochlorite…

Beers, Mande; Archer, Crystal; Feske, Brent D.; Mateer, Scott C. – Biochemistry and Molecular Biology Education, 2012
Current cutting-edge biomedical investigation requires that the researcher have an operational understanding of several diverse disciplines. Biocatalysis is a field of science that operates at the crossroads of organic chemistry, biochemistry, microbiology, and molecular biology, and provides an excellent model for interdisciplinary research. We…

Bergbreiter, David E.; Mijalis, Alexander J.; Fu, Hui – Journal of Chemical Education, 2012
Reversible polymer dehydration and precipitation from water due to the unfavorable entropy of hydration is examined using a melting-point apparatus. The thermoresponsive lower critical solution temperature (LCST) behavior of poly(N-isopropylacrylamide) (PNIPAM) is responsible for these effects. An experiment is described that allows students to…

Matz, Rebecca L.; Rothman, Edward D.; Krajcik, Joseph S.; Banaszak Holl, Mark M. – Journal of Research in Science Teaching, 2012
Laboratories have been a cornerstone in teaching and learning across multiple scientific disciplines for more than 100 years. At the collegiate level, science laboratories and their corresponding lectures are often offered as separate courses, and students may not be required to concurrently enroll in both. In this study, we provide evidence that…

Straulino, S.; Orlando, A. – Physics Education, 2012
The basic theory of radio broadcasting is discussed from an experimental point of view. First, concepts like wave modulation and tuning are explained with the use of instruments in the physics laboratory. Then, a very basic radio receiver is described and assembled, whose most important feature, like in the old "crystal radios", is the absence of…

McKenzie, Nancy; McNulty, James; McLeod, David; McFadden, Meghan; Balachandran, Naresh – Journal of Chemical Education, 2012
A new undergraduate program in chemical biology was launched in 2008 to provide a unique learning experience for those students interested in this interdisciplinary science. An innovative undergraduate chemical biology laboratory course at the third-year level was developed as a key component of the curriculum. The laboratory course introduces…

Benz, Lauren; Cesafsky, Karen E.; Le, Tran; Park, Aileen; Malicky, David – Journal of Chemical Education, 2012
This article describes a simple and inexpensive undergraduate-level kinetics experiment that uses magnetic levitation to monitor the progress and determine the activation energy of a condensation reaction on a polymeric solid support. The method employs a cuvette filled with a paramagnetic solution positioned between two strong magnets. The…

Elkins, Kelly M.; Kadunc, Raelynn E. – Journal of Chemical Education, 2012
In this laboratory experiment, real-time polymerase chain reaction (real-time PCR) was conducted using published human TPOX single-locus DNA primers for validation and various student-designed short tandem repeat (STR) primers for Combined DNA Index System (CODIS) loci. SYBR Green was used to detect the amplification of the expected amplicons. The…

Egts, Haley; Durben, Dan J.; Dixson, John A.; Zehfus, Micheal H. – Journal of Chemical Education, 2012
A method is presented for the determination of ["alpha"]- and ["beta"]-acids (humulones and lupulones) in a hops sample using a multicomponent UV spectroscopic analysis of a methanolic hop extract. When compared with standard methods, this lab can be considered "greener" because it uses smaller volumes of safer solvents (methanol instead of…
