Smack dab in the middle of Chemistry Week (Oct. 18 - 24) is Mole Day, a holiday set aside not to honor the ground dwelling creature, but a measurement of mass. I take it that mole is short for molecule, because one mole is a mass (in grams) whose number is equal to the atomic mass of the molecule. This relationship was first discovered by Amadeo Avogadro (1776-1858), who received credit for the discovery after his death.
Chemist are a crazy bunch and they celebrate their holiday with a wacky spirit. Every year the Mole Day Foundation creates a theme and poster for the event. This year’s theme is “Mole of Fortune” complete with a mole Pat and Vanna. I hope someone sends them this poster!

There are creative ways to celebrate this holiday with family or in the classroom. This is a great holiday for fun and of course food. Last year I included a mole sauce recipe, this year try my favorite guaca-mole.
Ingredients
2 really ripe Haas avocados
1 clove minced garlic
juice of 1 lime
1 tsp cumin
1 T fresh cilantro
1/2 chopped tomato
Cut avocados in half and dish out the insides. Mash the avocados and then mix in other ingredients.
If you want a super quick way to do this, add about 2 T or more to your taste of a really good salsa to the avocados. Let site for about 20 minutes so the flavors combine.
