Hey Scholars,
Here is your help on the difficult test I give. I realize it is easy to get frustrated in this class but keep your head up and keep working hard. For this weeks blog we are talking about Stoichiometry. I want to know a little history about this subject as well as this word we call the Mole (Mol). For this week add a historical fact about stoichiometry or give me the date of National Mol Day and things people do to celebrate this date. Have a great week
Mr. D

National Mole Day is either on October 23 (in two days) or June 2nd. This depends on your chemistry teacher. On this day chemistry students of your school do fun things such as have jokes, shirts, music, etc. Some people such as the ones in the article i read had a cake bake contest, scavenger hunt and made buttons. Some others do activities that have to deal with moles such as drinking 1 mol of H2O, Sending mole greeting cards and baking and eating 6.02 cookies. Sounds like something fun, we should do it but i dont think everyone would participate =[.

National Mole Day is on October 23 and was first established to get students more into chemistry. A mole is a basic unit of measurement in chemistry. NMD is usually celebrated from 6:02 a.m. to 6:02 p.m. which commemorates Avogadro's Number. Some people will play games and have alot of different classroom activies going on.

The idea of celebrating a National Mole Day was first proposed in the early 1980’s in an article
written by a teacher in the journal The Science Teacher. Then, in 1991, Maurice Oehler, a High School chemistry teacher, established the National Mole Day Foundation as a way of promoting the idea.

National Mole day is TODAYYYYY! :] October 23. Stoichiometry comes from two greek words stoicheion(element) and metron(measurement)
Also an interesting fact about stoichiometry is that in aquatic systems, the stoichiometry of available nutrients, such as nitrogen and phosphorus, has been used to predict phytoplankton species composition!

Mole day is an unofficial holiday that founded in the early 1980's and celebrated by american chemists on October 23 from 6:02 am to 6:02 pm. The time and date are from the avagadro constant which defines the number of atoms or molecules in a mole, which is about 6.022 x 10^23. High school science teachers around the country celebrate this holiday to possible help their students become more interested in chemistry with different fun activities.
the word Stoichiometria was used by Nicephorus to refer to the number of line counts of the canonical books of the New Testament and some of the Apocrypha. Huden Stoichiofaukrus read the measures and made provisions on the conceptual concepts of the era.
The word stoichiometry derives from two Greek words: stoicheion (meaning "element") and metron (meaning "measure"). Stoichiometry deals with calculations about the masses (sometimes volumes) of reactants and products involved in a chemical reaction. It is a very mathematical part of chemistry, so be prepared for lots of calculator use.

Celebrated annually on October 23, Mole Day commemorates Avogadro's Number (6.02 x 10^23), which is a basic measuring unit in chemistry.
1
On October 23 set your alarm clock for 6:00 a.m. in preparation for the 6:02 a.m. start of the celebration.
Step2
At 6:02 a.m. observe a moment of silence in honor of Avogodro's number and moles.
Step3
Dress in a Mole Day T-shirt or wear a Mole Day hat.
Step4
Send Mole Day greetings card (handmade paper or electronic) to others that appreciate the role chemistry plays in the world.
Step5
Hang a Mole Day flag or banner.
The National Mole Day Foundation's website also suggests eating a variety of Mole Day foods such as Moleasses cookies, Avogodro Dip or Taco-mole sauce.
Step8
If at 6:02 p.m. you still remember it is Mole Day, end the celebration with another moment of silence to reflect on Avogodro's contribution to science, or what you are going to eat for dinner.
hey mr.d.....heres a mol joke
What did Avogodro teach his students in math class?
