Today is a special day for Chemistry teachers and their students. I first heard about Mole Day from my favorite chemistry teacher, Wayne. He has created an entire program at the high school where he teaches to get the kids interested in chemistry. They do skits and play music and he ably plays the accordion. They eat food and have fun. I was lucky enough to be a small part of it this year.
Mole Day is a holiday celebrated among chemists in North America on October 23rd, between 6:00 AM and 6:00 PM, making the date 6:02 10/23 in the American style of writing dates. The time and date are derived from the Avogrado constant, which is approximately 6.023×1023, defining the number of particles (atoms or molecules) in a mole, one of the seven base SI units.
Mole Day originated in an article in The Science Teacher in the early 1980s. Inspired by this article, Maurice Oehler, now a retired high school chemistry teacher from Wisconsin, founded the National Mole Day Foundation (NMDF) on May15th 1991. Many high schools around the United States and in Canada celebrate Mole Day as a way to get their students interested in chemistry, with various activities often related to chemistry or moles.
