Chemical compounds and reactions as found in the world of plants were the basis for a new one-semester general education lecture course for college students. A separate laboratory course that included two field trips further elaborated on the lecture themes. Plant-related topics, from carbon dating and soil chemistry to plant colors, odors, and poisons, were used to introduce and illustrate increasingly complex chemistry topics: beginning with atoms, ions, and molecules the lectures progressed to the structures of organic molecules in plant pigments, fragrances, and toxins. Additional sections on plant-derived foods, dyes, and medicines stressed human dependence on plant compounds. The development of the course was strongly motivated by the effort to improve science literacy of a general student body and to excite students for chemistry. The success of the course was shown in a doubling of class enrollment compared to earlier general education lecture classes in the department, in active and consistent student participation during lectures, and in the student effort devoted to lecture and laboratory final projects.

Our Secondary School editors work hard to distill all the JCE materials to produce a fraction of particular interest to high school teachers. We call it CLIC.
In recent years we have worked hard to better match our advertisers with our readers. When shopping for chemistry education materials, visit our advertisers' WWW sites first.
