Well that’s because this all-important day has nothing to do with the animal, but commemorates Avogadro’s number (6.02 x 10 23) – a unit of measurement. The time duration of Mole Day recognizes Avogadro’s Number, which is a basic measuring unit in chemistry. Avogadro number is denoted as 6.02×10 23. One mole is a mass (in grams), the number of which equals the molar mass of a molecule. Mole is one of all the seven base SI units.

MOLE DAY!Mole Day will be observed Tuesday, October 23rd, between 6:02 am and 6:02 pm

Chemists Unite!! The Day of A-Mole-nent is Approaching!!

Forewordby Webmaster

It is 6:02 a.m. on October 23rd of any year at Hutch-Tech High School. On any other day, you might see a couple of teachers (dedicated, committed, or should be committed) pulling into the parking lot. Perhaps you might see a custodian unlocking the door. On any other day, you would more than likely not see a student around, let alone 300+ students standing outside of Tech. But then again, this is NO ORDINARY DAY!

October 23rd for any other person is just what it is called, October 23rd. But for a Hutch-Tech student, it is Mole Day!!! A day for frolicking with the mighty Mole! To be honest with you, I never heard of Mole Day when I was in high school in Williamsville. And for good reason, I was a high school student in 1977-1981. This did not start until 1991. But upon my arrival at Tech in 2001, I arrived on Oct. 23 for work and was astonished to see 300+ students standing outside in the cold wind. Still I did not really understand the Mole Day phenomenon.

Mr. Hurley and Mr. Pearson were outside with these students, raising a flag, blowing up things, reciting the Pledge to the Mole, and other activities. My first thought was that THEY WERE NUTS!! How right I was - and how much fun it was. There is a search for the hidden Mole within the building. Here we have seniors, our most mature students (so we think), searching the building. Looking for a stuffed mole. How many other high schools have their BMOCs looking for a stuffed animal!

So, below is our Mole Day page. Some of the information comes from the National Mole Day Foundation Website....enjoy! And HAPPY MOLE DAY!!

What is Mole Day?

Celebrated annually on October 23 from 6:02 a.m. to 6:02 p.m., Mole Day commemorates Avogadro's Number (6.02 x 10^23), which is a basic measuring unit in chemistry. Mole Day was created as a way to foster interest in chemistry. Schools throughout the United States and around the world celebrate Mole Day with various activities related to chemistry and/or moles.

For a given molecule, one mole is a mass (in grams) whose number is equal to the atomic mass of the molecule. For example, the water molecule has an atomic mass of 18, therefore one mole of water weighs 18 grams. An atom of neon has an atomic mass of 20, therefore one mole of neon weighs 20 grams. In general, one mole of any substance contains Avogadro's Number of molecules or atoms of that substance. This relationship was first discovered by Amedeo Avogadro (1776-1858) and he received credit for this after his death.

MOLE PLEDGE

Avogadro's Numbers

(Background: 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!)

Formula Avogadro's Number

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.

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.
