Experiments and Other Learning Activities Using Natural Dye Materials


  • Veronica A. Burrows Arizona State University


Natural raw materials have advantages for use in chemical engineering laboratory courses, including safety, environmental responsibility, and aesthetics, as well as pedagogical advantages for students, including an opportunity to work with raw materials and in a topic area where "right" answers are not readily available. We describe a statistical design of experiments (DoE) laboratory experience using natural dyestuffs and a survey of its learning effectiveness. In addition, other potential additional uses of natural dyestuffs for experiments or hands-on recruiting experiences are outlined.
