…. Have you ever had this happen: You are minding your own business, teaching your life science course, it’s early in the term. A student, on the way out after class (never at the beginning of class, rarely during class) mentions something about “carbon dating.” This usually happens around the time of year you are doing an overview of the main points of the course, but before you’ve gotten to the “evolution module” (more on the “evolution module” another time … or come to the Bell on Friday to hear me rant about that in person).
The student is talking about C14 dating and how it “has problems.” But you are a life science teacher and can’t think of a single point in your class that you really touch on C14. Dating in the evolution section does not involve C14. This is for later time periods, more in the area of archaeology, and you know nothing about it. So you brush off the question but are left with an uneasy feeling.
