Asked to be a judge for Carnival Queen this year, I accepted with alacrity. And probably became the first judge ever to ask all the candidates a metallurgical question involving the lever rule—a question I knew no-one would know the answer to (none were materials science and engineering majors, who would have the best shot at knowing the answer). The object of the question was focused on critical thinking.
The Saturday morning before Carnival Week was day one of my judging. In my training, I was told I could ask any questions I wanted, and was given a set of standard questions to choose from.
“Any questions?” I repeated?”
“Yes, anything you want—just ask everyone the same questions.”
I warmed them up with a few standard questions: “Why do you want to be Carnival Queen,” and “Why did you choose to come to Michigan Tech,” and then stepped right into it, by going to the board and drawing a banana-shaped phase diagram, labeling the axes, temperature versus component (we used a gold/silver phase diagram).
I warmed them up to it by talking about how a pure component below its melting point was solid, and then after it was heated past its melting point, it was liquid. And then I explained how with a binary alloy with soluble components, the extra component adds a degree of freedom to the system. And that in turn gives such alloys a range of temperatures over which both liquid and solid are present. Then, I identified a state point in this two-phase region, just below the liquidus for a 50/50 alloy, and asked: “At this temperature and composition, we see there is both liquid and solid present. My question is: Do you think the mixture will be mostly liquid, or mostly solid?”
A few candidates asked clarifying questions, a few reasoned out loud. And, as I had hoped, given how we really stress critical thinking across all majors, all got the answer right. When I followed up and asked them why they thought it would be mostly liquid, the reasoning was sound—they tied it in with proximity to the liquidus or to the point being at a higher temperature. Very proud of all the Queen’s Finalists!
The second judging event took place the following Saturday night, during the Coronation. That evening, I enjoyed seeing all the candidates again, this time formal attire. They answered questions up on stage with last year’s Queen—a much higher pressure situation than I think I put them under! All of the finalists did a great job, and I am pleased to report that this year’s Carnival Queen is a Guardian of the North, Riley Simpson, whose passion is for flying, and whose musical talent was evidenced by an elegant and lively performance on the xylophone.
Riley is a fourth-year Mechanical Engineering student and member of the Advanced Metalworks Enterprise who will be commissioned as an Air Force officer when she graduates, and I’m confident she will go far in her career.
It was my great honor to meet all these confident, intelligent, talented, and service-oriented Winter Carnival Queen’s finalists. My last interview question, back on that first Saturday, was, “Do you have any questions for me?” It was immediately evident that they had not anticipated being asked to ask a question (I was mimicking a job interview). And, they all rallied, and with a variety of questions, such as, “Why did you come to Michigan Tech,” and “What does a dean do?” My favorite question came from one candidate who asked me, “Did you ever do anything like this (meaning, run to be Carnival Queen)? “Oh my goodness no!” I exclaimed. “It took me many years to get the confidence to be in the public eye.” It took me about an additional two decades!
Now, if you’re interested in learning the answer to the question I asked the Winter Carnival Queen contestants, “mostly liquid or mostly solid”—or want to hazard a guess, feel free to contact me, email@example.com.
