Kinetic Analysis of Amylase Using Quantitative Benedict's and Iodine Starch Reagents Beverly Cochran, Deborah Lunday, and Frank Miskevich
This laboratory emphasizes that enzymes mediate the conversion of a substrate into a product and that either the concentration of product or reactant may be used to follow the course of a reaction. It does so by using an inexpensive scanner and open-source image analysis software to quantify amylase activity through the breakdown of starch and the appearance of glucose.

Photooxidation of Bilirubin to Biliverdin and Bilirubin Structure A. F. McDonagh and D. A. Lightner
Two recent articles in this Journal dealt with bilirubin (BR), the yellow pigment of neonatal jaundice. While BR is a fascinating biomedically-relevant tool for teaching photochemistry and stereochemistry, both articles are minefields of misinformation whose main pedagogical use might be as examples of error.

Solar Irradiation of Bilirubin: An Experiment in Photochemical Oxidation A. E. Pillay and F. M. Salih
Describes an experiment on photochemical oxidation employing solar irradiation of bilirubin followed by spectrophotometric absorption. The bilirubin undergoes depletion, and the declining concentration can be expressed exponentially as a function of time. The instantaneous reaction rates, half-life, and rate constant can be derived directly from the exponential plot.

A Modified Demonstration of the Catalytic Decomposition of Hydrogen Peroxide Carlos Alexander Trujillo
A safer and cheaper version of the popular catalyzed decomposition of hydrogen peroxide demonstration commonly called the Elephants Toothpaste is presented. Hydrogen peroxide is decomposed in the presence of a surfactant by the enzyme catalase producing foam. Catalase has a higher activity compared with the traditional iodide and permits the use of diluted hydrogen peroxide solutions. The demonstration can be made with household products with similar amazing effects.

Chemiluminescent Oscillating Demonstrations: The Chemical Buoy, the Lighting Wave, and the Ghostly Cylinder Hernán E. Prypsztejn
In this article, a chemiluminescent oscillating reaction is presented in which a chemiluminescent substance (luminol) interacts with a chemical oscillator producing an oscillating chemiluminescence. This demonstration has been successfully performed in basic chemistry courses to arouse interest and curiosity in students. This demonstration fascinates audiences and in courses for science majors it is an excellent way to introduce complex concepts such as far-from-equilibrium conditions, nonlinear dynamics and bifurcation, and chaos theories.

Using Organic Light-Emitting Electrochemical Thin-Film Devices To Teach Materials Science Hannah Sevian, Sean Müller, Hartmut Rudmann, and Michael F. Rubner
Light-emitting thin films provide an excellent opportunity to learn about principles of electrochemistry, spectroscopy, microscopic structure of the solid state, basic circuits, and engineering design. There is currently strong interest in academic and industrial engineering research centering on developing organic light-emitting devices for applications in flat panel displays. In this educational module, designed for high school or introductory undergraduate courses, students learn how to make a ruthenium-based thin-film device. In the process, they learn about the solid-state electrochemistry at work in the film, as well as the electroluminescence that results when current passes through the device.

It also lets students discover that to increase a reaction's rate, a catalyst need only provide any additional pathway for the reaction, not necessarily a pathway having a lower activation energy.

A simple and effective method to demonstrate the phenomenon of photocatalytic degradation of a gaseous organic pollutant was developed. Titanium dioxide (anatase) was used as the photocatalyst, and sunlight was found to be an effective light source for the activation of TiO2. The organic pollutant degrade in this demonstration was a common indoor air pollutant, dichloromethane.

A Laboratory Experiment Investigating Different Aspects of Catalase Activity in an Inquiry - Based Approach Doris R. Kimbrough, Mary Ann Magoun, Meg Langfur
The action of the enzyme catalase on aqueous hydrogen peroxide to generate oxygen gas is a well-established demonstration. Catalase is typically obtained by aqueous extraction of a potato, and the potato extract is mixed together with 3% hydrogen peroxide. The oxygen that is produced can be collected over water. Variations on the procedure can demonstrate the dependence of catalytic activity on temperature or the presence of inhibitors.
