Chemical engineers have a breadth of opportunity to utilize their skills in projects involving the life sciences and medical field, yet the misconception that this is not the case is noted to be prevalent at the undergraduate level. This perception can misguide underclassmen students as they choose between chemical engineering and bioengineering as a major. We propose the use of two hands-on, interactive learning tools to expose freshman-level chemical engineering undergraduate students to applications that go beyond the traditional oil refining and catalysis foci. The first device simulates fluid flow phenomena that occur in blood vessels that widen due to an aneurysm. The design features transparent tubing with a rounded, expanded midsection and standpipes to allow students to easily observe pressure trends. The second device introduces students to blood separation principles through the use of an entertaining and simple fidget-spinner-inspired centrifuge design. On each arm of the spinner, there exists a clear chamber filled with fluid and microbeads at various ratios, which simulates the effect of blood cell density and size on settling speed and terminal position—phenomena that are utilized to enhance blood separation efficiencies. Both devices will be implemented in a spring 2020 Introduction to Chemical Engineering (CHE 110) course along with motivational surveys to assess pre- and post-implementation attitudes toward chemical engineering. We hypothesize that focusing on biomedical applications early in student undergraduate experience will help them understand that traditional chemical engineering knowledge can be easily transferred to biological systems, with the potential of increasing retention of women, who as a population tend to gravitate more toward public-service-oriented careers.
