Connections to Chemistry Concepts (for correlation to course curriculum)

1. 
   Organic Chemistry—The article’s discussion of esters can be linked to the topics of organic structures, functional groups, and nomenclature. The article shows the reaction of a carboxylic acid and an alcohol to form an ester, in both general and specific examples. Students could investigate different combinations of acids and alcohols, with their accompanying structures, names, and odors.
   
2. 
   Biochemistry—The senses of taste and smell are discussed in the article. The ways that chemicals are sensed through taste and smell could be investigated.
   
3. 
   Enzymes—Receptor protein cavities in the nose are certain shapes that allow only certain odorant molecules to dock with them, as in the familiar lock-and-key manner associated with enzymes.
   

Possible Student Misconceptions (to aid teacher in addressing misconceptions)

1. 
   “The flavor of a food or beverage is only a result of information collected by our taste buds.”Flavor is a combination of the senses of both taste and smell. Smell is actually the most dominant aspect of flavor. Other things also contribute to our perception of flavor, including temperature, texture, and color of the food or beverages.
   
2. 
   “The flavor of a food or beverage is the same all of the time.”The flavor of a food or beverage changes depending on how it is prepared or cooked. For example, tomatoes could be prepared as a sauce with various spices, dried until crunchy, served cold in a salad, as a juice, etc. These preparations can affect the temperature, texture, and color of a food, which also affect how we perceive its flavor.
   
3. 
   “To recreate the natural flavor of a food and make an artificial flavor, we need all the flavor compounds from that food.”We don’t need all the flavor compounds in a food to recreate its flavor. For instance, an orange contains 250 aromatic chemicals, which all combine to create an orange flavor. In contrast, artificially-flavored Tang has only six aromatic chemicals in its makeup, yet it tastes like an orange.

Anticipating Student Questions (answers to questions students might ask in class)

1. 
   “Can all flavors be duplicated?” The book Food Bites: The Science of the Foods We Eat (Hartel, R. W.; Hartel, A. Food Bites: The Science of the Foods We Eat; Copernicus Books: New York, 2008) states “Flavor chemists synthesize imitation flavors by analyzing all the different component chemicals that go into a flavor, then mixing together the primary chemical components in those flavors. Many artificial flavors, such as strawberry and cherry, can be quite close to the natural version because they contain just a few main flavor chemicals. Because of the broad spectrum of chemical components in chocolate, some of which are found at extremely low, but significant, levels, a decent imitation chocolate remains elusive.” (pp 60–61) (available at http://books.google.com/books?id=PMOrW3zkirwC&pg=PA60&lpg=PA60&dq=synthetic+chocolate+flavor&source=bl&ots=-IPIwytUS7&sig=JO5scR6z4pE5h_uzOc4BTg1nW7s&hl=en&ei=zZeKTq7HCcfksQLqn9WlBA&sa=X&oi=book_result&ct=result&resnum=5&ved=0CEsQ6AEwBA#v=onepage&q=synthe)
   
2. 
   “Do all esters smell pleasant?”When one thinks of esters, they are most often associated with a pleasant, often fruity, smell. However, not all esters even have an odor and some may have an odor we find unpleasant. For example, the ester ethyl acetate is found in nail polish remover, model paint, and model airplane glue, most likely smells we would not enjoy.
   

In-class Activities (lesson ideas, including labs & demonstrations)

General Chemistry 1 Practice Exam

1. 
   The December 2003 ChemMatters Teacher’s Guide (http://portal.acs.org/portal/PublicWebSite/education/resources/highschool/chemmatters/CTP_005457) describes one activity as, “A somewhat nonscientific comparison of different types of vanilla”, where the Teacher’s Guide author and his wife investigated imitation vanilla and pure vanilla extract to answer the questions: “(1) Can we discern any difference, and (2) which product would we prefer if we couldn’t see the labels?” (pp 21–23).
   
2. 
   The combination of taste, smell, texture, appearance, etc. to give us a perception of a particular flavor can be investigated by students using actual food using the JCE Classroom Activity “Apple Fool! An Introduction to Artificial Flavors” (J. Chem. Educ.2003, 80 (4), pp 408A–B). The description of the activity reads, “Students investigate flavorings by making artificial ‘cooked apples’ from a mixture of crackers, sugar, cream of tartar, and water, as is done for the filling in recipes for Mock Apple Pie. The mixture looks much like applesauce, and the Activity can be extended to include taste testing and pie baking.” (J. Chem. Educ.2003, 80 (4), pp 408A–B)
   
3. 
   Laboratory manuals and textbooks often include an experiment where students make different esters by reacting various combinations of carboxylic acids with alcohols in the presence of a catalyst such as sulfuric acid. One laboratory is available in ChemCom, 5^th ed., pp 275–277; students make esters that smell like wintergreen, banana, and orange. Another laboratory is in ChemSource 3.0, Organic Chemistry Module, pp 5–10.
   
4. 
   Students can try the “orange juice test” described in the April 1995 ChemMatters article “Why does orange juice taste so bad after you brush your teeth?” The directions read: “Take a sip of orange juice and note the relative strength of the sweet, sour, and bitter tastes. Rinse your mouth with water, then vigorously brush your teeth with SLS-containing toothpaste [sodium lauryl sulfate]. Rinse with water again, then taste the orange juice again. Are the relative intensities of the tastes very different?” (p 15)
   
5. 
   Have students compare their ability to identify foods using taste alone, versus taste and smell together. Two “smell and taste test” experiments available online are http://www.reachoutmichigan.org/funexperiments/agesubject/lessons/newton/tstesmll.html, which uses jelly beans, and http://faculty.washington.edu/chudler/pdf/tastetg.pdf, which uses various food items, and asks students to devise their own experiment regarding the sense of taste. (from ChemMatters October 2010 Teacher’s Guide, p 57, http://portal.acs.org/portal/PublicWebSite/education/resources/highschool/chemmatters/archive/CNBP_025802)
   
6. 
   Students can investigate the linkage of taste and the color of a beverage. Students could color drinks using different colors of food dye and study whether the color of the drink affects flavor identification by a taster. A site summarizes studies that examined the results of similar activities (see http://faculty.washington.edu/chudler/coltaste.html). (from ChemMatters October 2010 Teacher’s Guide, p 57, http://portal.acs.org/portal/PublicWebSite/education/resources/highschool/chemmatters/archive/CNBP_025802)
