What is your definition of the term “mole” in chemistry? Many articles have been written about the term and the confusion surrounding it. It was not considered an SI unit (with an IUPAC definition) until 1971. IUPAC is considering a change to the 1971 definition. There has been discussion about whether the SI definition of the mole as determined by IUPAC necessarily needs to be identical to the definition used by chemists and teachers. This article provides a short list of some recent JCE articles discussing the change and what it might mean for teachers while also considering some misconceptions related to the mole in chemistry class.

An advantage to teaching on the trimester schedule allows me the opportunity to teach the same course again roughly twelve weeks later. So after grading my 2nd trimester students’ Chemistry B final exams, I was able to evaluate certain topics that caused my students problems, reflect on my teaching, and then determine how I was going to better prepare my students in the 3rd trimester chemistry B class.
An outline for the Halloween Chemistry Show Demonstration at Saint Mary’s College, Notre Dame IN, is presented. Organized by Saint Mary’s Affiliate of the American Chemical Society (SMAACS) student club, this show has become an annual event with an average attendance of over 200 people. The club’s main goal is to generate interest in the sciences among children; while stimulating a pursuit for continued education and hopefully future careers in STEM fields. The Halloween Chemistry Show aspires to that goal by providing an interactive experience for all children in attendance while presenting thought-provoking demonstrations for the entire audience.
