Mole Day: October 23

Updated on October 23, 2014

How to Celebrate Chemistry's Greatest Holiday: Mole Day

October 23 is Mole Day! It is the day we celebrate the mole. No, not mole the animal, and not mole the congenital growth; not mole the sauce, or even mole the spy. Mole Day celebrates the mole that is a SI unit measuring the quantity of a substance. And, scientists (who are known for letting loose and partying) have a great time on Mole Day.

So let loose, you chemistry freaks, and have a day filled with pun.

So, What Is Mole Day?

Explanation of Chemistry's Most Cherished Holiday

Mole Day is an unofficial holiday celebrated scientists, specifically chemists on October 23, between 6:02am and 6:02pm.

The holiday day celebrates the mole, a scientific unit measuring the quantity of a substance which is used in chemistry. The term mole is likely derived from the german word Molekül meaning molecule. The first usage in English dates from 1897, in a work translated from German.Some sources place the date of first usage in English as 1902.

The date and time of Mole Day is a direct result of Avogadro's constant which defines the number of particles (atoms or molecules) in a mole. Avogadro's constant is 6.02 Ã 10^23.

Mole Day is widely celebrated, predominatly in educational institutions, and is quite a tradition in High Schools in the United States and Canada. One of the great traditions of Mole Day is the pun, and the dorkier the better. It is science after all, we embrace dorky.

Pledge of Allegiance

When saying the pledge of allegiance to the U.S. flag, one faces the flag. If no flag is present, one should face our nation's capitol, Washington D.C. When saying the pledge to the mole, a real mole is usually not present. So, one should bend over and face the earth!

I pledge allegiance to the mole, and to the science from which it comes, one SI unit, extremely divisible, with micromoles and millimoles for all.

(By: R. Thomas Myers - Kent State University, Kent, OH)

I pledge allegiance to the mole, to the International Union of Pure and Applied Chemistry, and to the atomic mass for which it stands, one number, most divisible, with atoms and molecules for all.

(By: Sylvia Cooper - Morgantown High School, Morgantown, WV)

Avogadro's Law

aka: Avogadro's theory, Avogadro's hypothesis

Avogadro's Law is a principle stated in 1811 by the Italian chemist Amedeo Avogadro (1776-1856). (That's the handsome Avogadro to the right.)

"equal volumes of gases at the same temperature and pressure contain the same number of molecules regardless of their chemical nature and physical properties".

This number (Avogadro's number) is 6.023 X 1023.

It is the number of molecules of any gas present in a volume of 22.41 L and is the same for the lightest gas (hydrogen) as for a heavy gas such as carbon dioxide or bromine.

Avogadro's number (conventionally represented by N' in chemical calculations) is now considered to be the number of atoms present in 12 grams of the carbon-12 isotope (one mole of carbon 12) and can be applied to any type of chemical entity.

Why is the mole significant? What can we do with it?

Creative Mole Day Projects

Mole Puppets

Put together a mole puppet show with a stuffed puppet like these, or paper moles on a stick.

You could do a Mole Day puppet show with this little guy. Maybe you could add a Bunsen & Beaker puppet to interact with him.

 

Ideas for Creative Mole Day Projects

Be bold and creative with your project

  • Create a Mole Day board game: Mole-opoly, a Chemisty Land (Candy Land), etc.
  • Write an original Mole Day song
  • Make a chemistry mole-bile to hang from the ceiling
  • Scavenger Hunt - Create a list of household items using the chemical compound. Such as: Something that contains NaHCO3
  • Write a Mole Day poem - Ode to the Mole
  • Create a Mole Day comic book
  • Design a Mole Day flag - hold a flag raising at the school's flagpole.
  • Create a fake newspaper with all articles chemistry or mole related. Include some made up articles, ads, obituaries, movie reviews, etc

Mole Day Video Project Ideas

Make a video as your Mole Day Project

  • Mole Day Spoof - spoof a movie or TV show. For instance, Mole Day the movie, as spoof of Groundhog Day.
  • Mole Day Man on the Street - acting like a reporter, as random people Mole Day questions.
  • Mole Day Daily Show Corespondent - do a news report in the style of Comedy Central's The Daily Show (keep it clean)
  • Mole Day Game Show - Wheel of Fortune, Price is Right, Are You Smarter Than a 9th Grade Chemistry Student?
  • Mole Day Reality Show - spoof a reality show (maybe the Mole?) by having scientific characters - Salt, Oxygen, Water, Noble Gas, etc. The challenges could be exposure to heat, electricity, water, acids, etc.
  • Mole Day Youtube Style - do a parody of a famous youtube video like One World, Human Space Invaders, or OK, Here It Goes Again

      Oh good! Mole Day is far enough off that I can take my time in nabbing my mole(s) from my backyard. The little rascals have been tunneling all over the place. Cool holiday.

      That was one interesting chemistry lesson she gave us....

      Good lens though xD

      There are a couple of moles in my backyard that I mistook for very large mice and they have been burrowing holes to the sub-floor of my house which is a not a good thing. I am just surprised that there is such a thing as a Mole Day.

      We knew about Pi day, but this is the first we've heard of mole day. You have forced us to consider that there are actually people on Squidoo nerdier than us. This is at once a comfort and somehow profoundly disturbing. :-)

      I had never heard of this day, and I'm educated to be a chemistry teacher. S0unds like fun though :) as the review on the giant squido community showcase blog shows: perhaps you should explain what an SI unit is?

      When I taught Chemistry, we always celibrated MOLE day. Nowadays... I don't think the younger teachers have ever even heard of it.

      Great tribute
