- Abstract:
Baking soda can be used as an indicator of how much acid a substance contains. Lemons and limes have more acid in them than grapefruits and oranges. Indophenol can be used as an indicator of how much vitamin C is in a substance.

- Abstract:
In Chiapas, one of the poorest states in Mexico, an estimated 150,000 children are malnourished. To end this problem, governments have implemented food security policies, including food importation and industrial food production. In 2008 alone, Mexico imported 20 million tons of food. While these policies certainly help to remedy the problem in the short term, the massive importation of basic foodstuffs and incentives to industrial agriculture may widen social inequality, threaten health and deteriorate biodiversity and ecosystem services. I will present the objectives and achievements of initiatives born in the highlands of Chiapas to enhance local food production free of hazardous pesticides and appropriate to the culture of the region. Examples include the rescue of local knowledge for food production, a school gardens program and the Network of Producers and Consumers for Healthy Local Food.

Highlights of this course include: Major biological, chemical, and physical components of the agricultural systems The scientific basis for understanding these systems and their management How science has influenced policies related to agriculture, food safety, and the environment in the United States How the policies have evolved over time in the US What has worked and what has not; the reasons and the consequences What other factors influence policies beyond science How we link what we learn to ecological agriculture How we use what we learn for policy analysis

- Abstract:
In this decision case, a congressional staffer must weigh a number of competing concerns and issues, including popular reactions to genetically modified organisms, in deciding how to present information to her boss, an influential congressman drafting legislation to support agricultural research. The case explores the social and biological issues surrounding micronutrient malnutrition, including deficiencies of several vitamins and essential minerals, especially iron, iodine, and vitamin A, which affect at least one-third of the world's population, primarily in developing nations. Developed for a graduate-level seminar on "Genomics, Agriculture, Food Systems and Development," the case teaches about the issues surrounding genomic applications in agriculture and their implications to health, environmental stewardship, economic sustainability, and national development.

- Abstract:
This case is a "clicker" adaptation of a similarly titled case by Merle Heidemann and Gerald Urquhart of Michigan State University, "A Can of Bull?" The story introduces students to basic principles of metabolism and energy through a biochemical analysis of commonly available "energy drinks" that many students purchase at relatively high prices. Students learn to define energy in a biological/nutritional context, identify valid biochemical sources of energy, discuss how foods are metabolized to generate ATP, and critically evaluate marketing claims for various energy drinks. The case can be used in introductory level courses to introduce these principles or as a review of basic biochemistry and nutrition for upper-level students in nutrition, physiology, or biochemistry courses. The case is presented in class using a PowerPoint (~2.3MB) that is punctuated by multiple-choice questions students answer using personal response systems, or "clickers."

- Abstract:
This cereal contains a lot of sugar. If the cereal was put into a bag with yeast, the bag would puff up a lot because the yeast uses the sugar to grow. Carbon dioxide gas is produced as a byproduct, making the bag puff.

- Abstract:
When Mitchell reveals that he is going on a low-carb diet, Janine tries to talk him out of it, telling him that he's too thin as it is and doesn't need to loose any weight. Designed to accompany a nonmajors unit on human anatomy and physiology, this interrupted case study has students applying what they learn about human body systems to Mitchell's fad diet claims and Janine's sharp criticisms. Supplementary links help students explore new discoveries about appetite-controlling hormones, how body image may influence people's dietary decisions, and some of the most common diet myths.

- Abstract:
This case study is designed to teach students at various levels about large biomolecules, nutrition, and product analysis. Students conduct a biochemical analysis of several popular energy drinks on the market, which many students purchase at fairly high prices, and determine whether these products nutritionally match their marketing claims. The case can be used as a review of basic biochemistry and nutrition for upper level students in physiology, biochemistry, or nutrition courses, or to introduce this information in introductory level courses in these disciplines.

- Abstract:
Colony Collapse Disorder (CCD) has claimed approximately one-third of the commercial honeybee population in recent years. A number of causes have been suggested for this phenomenon, including the consumption of high fructose corn syrup (HFCS) by the bees. This directed case investigates the issues and chemistry that might be involved in CCD related to HFCS. The case was developed for use in an undergraduate organic chemistry or food chemistry course.
