My own interest in science stems from my hands-on experiences as a child. Therefore, many demonstrations were included in this seminar – at least one demonstration during each seminar meeting. These demonstrations were chosen so that they could actively involve the participants and at the same time illustrate the scientific principles related to the Chemistry of Everyday Things.
The book by Cathy Cobb and Monty L. Fetterolf entitled The Joy of Chemistry: The Amazing Science of Familiar Things was used as the primary text for the seminar. During our first meeting in May, we generated a list of topics for discussion during the intensive session in July. These included Personal Care Products, Cleaning Products, Antifreeze and Deicers, Batteries, Hot and Cold Packs, Biofuels, Gunpowder and Fireworks, Refrigeration, and Plastics. Each Fellow then chose one of these topics and prepared a demonstration (or two or sometimes three) related to this topic to present during one of our meetings in July. I also provided some of my own demonstrations. As a result, we had at least one demonstration during every seminar meeting, and sometimes several, that provided a great basis for further discussion. We discussed the chemistry for production and recycling of different types of plastics in some depth. A demonstration on the synthesis of nylon added to these discussions. Our discussion of the chemistry of cleaning products included a great demonstration on making soap. The discussion of antifreeze and deicers was enriched by a demonstration on ice cream, which the Fellows (and seminar leader) made and consumed with enthusiasm. Renewable energy is a key aspect of sustainability. With this in mind, the seminar included a discussion of biofuels and processes for solar energy conversion using artificial photosynthesis. A highlight of the seminar was the production of biodiesel fuel from cooking oil that culminated in the combustion of biodiesel fuel in an oil furnace burner.
The curriculum units developed from this seminar are suitable for elementary to middle-school to high-school students. In all of the units, the science content is integrated with language arts, mathematics and social studies to provide a balanced program that meets the literacy requirements of the school system. The Fellows have prepared extensive lists of materials that can be used in the classroom or as resources. These materials include books that the children can read, textbooks that the teachers can use, demonstration sourcebooks, suppliers of equipment, useful computer software, and addresses of sites on the World Wide Web. All of the Fellows developed units based on a theme or activity related to everyday things, including an innovative "survival chemistry" unit that illustrates the use of spiraling to reinforce the chemical principles from experiments to prepare pure water and biofuels. Other units are related to the chemistry of hair, cleaning products, batteries, weather, and plastics. The units include a number of excellent activities that will engage the students' interest by connecting to relevant topics and at the same time teach them about chemistry and sustainability.
I would encourage all teachers of elementary through high school students to review these curriculum units. These materials provide a valuable resource for incorporating topics of science and society related to the "Chemistry of Everyday Things" into the classroom.
