Electrochemical Cells(ChemPages Lab) John W. Moore, Jerrold J. Jacobsen, Joe L. March
Electrochemical Cells: this is a resource in the collection "ChemPages Laboratory Resources". The cell design described in this module includes two solutions connected by salt bridge (piece of string) and two electrodes (metal strips) connected to a voltmeter. The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.

Sunscreens William F. Coleman
Reinforcing the "Heath and Wellness" theme of National Chemistry Week 2004, the featured molecules for this month are all found in commercial sunscreens, or in the synthesis of sunscreen materials. The paper by Stabile and Dicks introduces students of organic chemistry to the synthesis of cinnamate esters used in sunscreen products. Several of the papers referenced by those authors, most notably a paper by Doris Kimbrough (J. Chem. Educ. 1997, 74, 51?53), present the structures of additional sunscreen components. Although the details of the synthesis are beyond the scope of most introductory courses, these molecules present an excellent opportunity for introducing students to the absorption of radiation that is far more relevant to their lives than the line spectra of hydrogen and other atoms. Such a discussion could be extended to include more delocalized dyes such as those frequently studied in physical chemistry courses as a test of particle-in-a-box models, and students could be asked about those molecules as sunscreens, which raises an interesting intersection between aesthetics and spectroscopy.

Molecular Models of Candy Components William F. Coleman
This month's Featured Molecules come from the paper "A Spoonful of C12H22O11 Makes the Chemistry Go Down: Candy Motivations in the High School Chemistry Classroom" by Fanny K Ennever on using candy to illustrate various principles. They include sucrose and the invert sugar that results from the hydrolysis of sucrose. Students should look for structural similarities between sucrose and the hydrolysis products glucose and fructose, and verify that all three are indeed hydrates of carbon. They should also inspect the models to see whether the position of the substituents in the five and six membered rings are the same in the sucrose and in the hydrolysis products. Also included are two esters important in fruit flavoring of candies. Flavor and aroma are inexorably intertwined in the taste experience and no single compound is responsible for that experience. Methyl cinnamate, included here, is one of over 100 esters, and over 300 compounds, involved in the taste of strawberries (1). Isoamyl acetate is a major component of the taste of bananas. Lastly, chocolate, perhaps nothing else need be said. There is a great deal of confusion in the popular press and on the internet between theobromine, found in cocoa beans, and caffeine. Both molecules are included here and students should easily see why the two might be confused. Consequently there are many exaggerated claims about caffeine in chocolate. An interesting assignment would be for teams of students to find reliable data on the physiological effects of these similar molecules, and to find good analyses on the actual level of caffeine in cocoa beans, versus the amount added in the candy production process, if any.

Chemical & Physical Change American Chemical Society
Everything you see and touch has the ability to change. Sometimes substances change to form new substances. This is called a chemical change. Other times substances change but keep the same identity. This is called a physical change. Try these activities to learn more about chemical and physical change.
