Lesson 1 - Introduction to Chemistry
Student Performance Objectives1. Explain the significance of the order of ingredients in a food label.2. Describe the difference between the main effect and the side effects of OTC and prescriptiondrugs. 3. Describe one chemical issue in the following common events: heart attacks, diabetes, bodybuilding, and the use of diuretics.Lesson OutlineLesson OutlineA. Why study chemistry? 1. Relevance to a society emphasizing chemicals a. Vitamin and mineral pills - bring to class and pass around Centrum or other vitamin/mineral bottles. b. Prescription drugs - bring in an antibiotic information/warning enclosure c. OTC medications - bring in a "cold/Flu" box d. Open advertising of drugs on TV and other media - have a contest and see who can accumulate the highest number of web addresses for drugs in 5 minutes of web-surfing. e. Ingredient lists for the knowledgeable consumer (1) Food packages - bring in a cereal box (2) Cosmetics - bring in Oil of Olay or similar packaging. 2. Fundamental to an understanding of Anatomy and Physiology a. About 70% of all the energy (ATP) produced by living cells is used to maintain cell membrane pumps that regulate chemical (ionic, organic) movements into and out of cells: cells pump out Na+ and pump in K+. b. Major side effects of the most commonly prescribed prescription drugs - the diuretics - involves potentially deadly deficiencies of potassium and magnesium ions. 3. Informed choices for future health of yourself and your family depend on understanding such "chemical" issues as a. Cholesterol and heart attacks. b. Triglycerides and cardiovascular disease risk. c. Blood glucose and diabetes. d. Protein for growth and bodybuilding. e. Salt and water balances - degree of hydration and athletics - "electrolyte" drinks for runners and basketball players.
