Creating Purple to Learn the Color Wheel Using a Colorful Anthocyanin Experiment
This work presents a method for teaching an artistic-mode chemistry lesson highlighting purple, a key color in the color wheel, using flowers and vegetables containing anthocyanins. The purpose is to provide students with experience observing color variations within a color wheel framework and to understand these variations chemically. The lesson consists of three parts: students first prepare five colors (i.e., red, purple, blue, green, and yellow), compare them with the sunlight spectrum to develop the color wheel concept, and finally explore how changes in chemical structure yield differences in color. Thus, students from elementary school to undergraduate are exposed to a wonderful color world in which hues are arranged in a ring shape, resulting in the understanding of purple–green harmony.
期刊介绍：
The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
