Nathan (5th grade) and Andrew (2nd grade) are my grandchildren (parents Marianne and Steve Lorenc). Philip Ball wrote: “Molecules are the smallest units of meaning in chemistry,” and “If atoms are letters, then molecules are words”. Therefore, if you wish to introduce chemistry to lower-grade-level students, you should introduce them to molecules. You could start with very simple molecules, and ask students to count C, H, O, and N atoms in each molecule. In this free, PDF product, eighteen, color, 3-dimensional atom and molecule images are provided for students who are asked to count the number of different atoms in each molecule. Though successful students
can graduate to more complex molecules (such as vitamins), they can always employ the principle of counting atoms.
I view “a supermarket as an educational environment”. It is an exciting place for students to learn about vitamin molecules, phytochemical molecules, aroma molecules, dietary minerals, and fresh fruits and vegetables. I hope to stimulate the curiosity of such students. Molecules and dietary minerals are my central focus in such an environment. They are (a) marketed as inexpensive, over-the-counter pills, (b) appear in nutrition labels, and (c) appear in tables of the nutritional characteristics of fresh fruits and vegetables. `Students should learn early and often that fresh produce is an important alternative to fast foods. A class field trip is impractical, but a parent/student field trip to a supermarket could be very useful. Timely and exciting education is one approach to the obesity problem in the U.S.
The free MOLECULES for Nathan and Andrew (supermarket series) serves as an introduction to three TpT products: (a) SUPERMARKET MOLECULES™, (b) SUPERMARKET NUTRITION™, and (c) 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.
For additional, adult-level information about molecules, fruits, vegetables, nuts, herbs, and spices, students and teachers could go to the online encyclopedia, Wikipedia. Also, for colorful images of fruits, vegetables, nuts, and herbs, students and teachers could go to Google Images.
I am professor emeritus of chemical engineering at Virginia Tech in Blacksburg VA. My email address is firstname.lastname@example.org . Since high school, I have loved chemistry. I thank my high-school teacher, Mr. Richard L. Miller for introducing me to this fascinating science during the 11th grade. He changed my life forever.
