Celebrating Mole Day is an opportunity to explore some important chemistry topics in engaging and sometimes quirky ways. Take advantage of Mole Day to have some fun with topics like measurement, scientific notation, and stoichiometry. Consider using Mole Day as a kickoff or culminating event for chemistry or interdisciplinary projects. The real point of the day is to generate enthusiasm and interest in chemistry.

## Mole Day Activities

• Kick off Mole Day activities at 6:02 a.m. with games like Mole-ionnaire, Mole-opoly, or Molympics.
• Build a Mole piñata and fill it with candy. Mass pieces of candy and determine the mass of 1 mole of the candy.
• Sculpt a mole (the four-legged variety) out of 0.5 or 1 mole of aluminum foil.
• Write a poem or song related to Mole Day.
• Write and/or tell mole jokes. These examples will get you started:

Why are moles bad at counting? Because they only know one number
What is chemical nonsense? Mole-arky
Where did Avogadro stay on vacation? A mole-tel

• Prepare some Mole Day snacks. Ask students to come up with their own Mole Day menus and provide the recipes. Represent the amount of compounds, such as salt (NaCl), sugar (C12H22O11), and baking soda (NaHCO3), in moles rather than teaspoons or cups. The recipes below will get you started:

Mole Mole-asses cookies Guacamole Mole-berry pie (Substitute another berry if mulberries are not available.) Mole-ton chocolate cake Car-Mole apples Orange Mar-Mole-Ade cookies AniMole crackers are a great ready-made alternative if you don't feel like cooking!

• Solve some out-of-the-ordinary mole problems such as: How long would it take to spend 1 mole of dollars if you spent 1 million dollars a day? Determine the average thickness of 10 pennies. How tall would a stack of 1 mole of pennies be?
• Investigate how many moles and atoms are in a given mass of a metal in this simulation: Amount of moles and atoms in metals simulation.
