A supermarket is an educational environment. The starting point for learning should be molecules. Why? The answer is because molecule names always appear in nutrition labels and in tables of the nutritional characteristics of fresh fruits and vegetables. Also, the characteristics of vitamins are described in Wikipedia articles (adult level).
This PowerPoint presentation (in PDF file format) provides colored, 3-D molecular structures for sixty-three molecules (13 vitamins, 4 sugars, 5 fats, 19 amino acids, 8 phytochemicals, 3 antioxidants, 3 preservatives, 7 aromas/oils, and one artificial sweetener ) of nutritional interest.
The 3D molecular structures provide a new technical vocabulary as well as visual aids to help students remember the molecules. For example: (a) fats and some phytochemicals have long chains of carbon atoms; (b) some vitamin molecules have letters (A, C, E, K, B6, and B12), whereas other vitamin molecules have names (niacin, riboflavin, folic acid, etc.); and finally, (c) there are nineteen different amino acids, both essential and non-essential;
Students can study, as I do, nutrition labels of packaged foods during breakfast time. For example, they can ask the following questions: How many grams of sugar per serving? Is any fiber present? What percentages of saturated fats and trans fats are in a serving? Is the processed food fortified with minerals and vitamins? And so forth. Such questions are evidence of a nutrition awareness about fast-food burgers, French fries, and fried chicken that is uncommon in kids and should be valuable over a lifetime.
The free MOLECULES for Nathan and Andrew (supermarket series) serves as an introduction to three TpT products: (1) SUPERMARKET MOLECULES™, (2) SUPERMARKET NUTRITION™, and (3) SUPERMARKET PRODUCTS™, two of which have yet to be uploaded to TpT. By the end of March 2014 (perhaps earlier), search TpT for the keyword, supermarket series, to access all of these products.
These three SUPERMARKET products are adapted from an adult-level TpT product entitled, “Enrichment Chemistry COMPLETE”. Please search TpT for the keyword, enrichment.
