Chiu, Yu-Chun; Jenks, Matthew A.; Richards-Babb, Michelle; Ratclif, Betsy B.; Juvik, John A.; Ku, Kang-Mo – Journal of Chemical Education, 2017
We report here the development of an inexpensive and engaging laboratory-based activity that can help students learn about the scientific method and the role of plant epicuticular waxes and surfactant function on waxy plant leaves as real life example in the agricultural industry. Three each of nontreated collard leaves ("Brassica…

Davis, T. A.; Athey, S. L.; Vandevender, M. L.; Crihfield, C. L.; Kolanko, C. C. E.; Shao, S.; Ellington, M. C. G.; Dicks, J. K.; Carver, J. S.; Holland, L. A. – Journal of Chemical Education, 2015
This activity allows students to visualize the electrolysis of water in a microfluidic device in under 1 min. Instructional materials are provided to demonstrate how the activity meets West Virginia content standards and objectives. Electrolysis of water is a standard chemistry experiment, but the typical laboratory apparatus (e.g., Hoffman cell)…

Abdul-Razzaq, Wathiq N.; Bushey, Ryan K. – Journal of College Teaching & Learning, 2009
Introductory physics labs provide many challenging yet applicable experiments and concepts to the many fields of engineering. One such lab has been developed at West Virginia University that explores resistivities of several different materials and ties this concept into electrical engineering practices and standards. Many students do not realize…
