# Mole Day Project Ideas

Instructor: Artem Cheprasov
What is a mole? Not the one on your skin or the one living in the ground! The one in chemistry! It's actually a big number and hard to grasp, but these easy projects can help you understand a mole more easily.

## How Big is a Mole?

A mole of something is 6.02*10^23 units of that thing. That's a gigantic number that's hard to wrap your head around! This project will help demonstrate how large that number truly is with more familiar examples. For example:

• How many times will a mole of dollar bills stacked on top of one another reach the sun and back?

To help answer this question, perform the following steps:

• Step 1: Get a blank medium-sized poster board or paper where all the information will be shown in visual and textual format.
• Step 2: State the problem. In this example, it would be: 'How many times will a mole of dollar bills stacked on top of one another reach the sun and back?'
• Step 3: Research the data necessary for this calculation and put it on the poster. This involves data on how thick a dollar bill is and the distance from the Earth to the Sun in the same units as the thickness of the dollar bill.
• Step 4: Write out the calculation that's used to determine how long (thick) a mole of U.S. dollar bills will be when all of them are stacked on top of one another. Also write out the calculation of how many times this length can reach the sun and back.
• Step 5: Use fun illustrations to demonstrate this concept, such as an image of the solar system and a bunch of dollar bills reaching the sun and back.
• Step 6: Cite the sources of information for Step 2.

You don't have to use this example. Other problems that can be solved in a similar way include:

• What weighs more: a mole of blue whales, the Earth, or the moon?
• A mole of Skittles would be able to fill Lake Baikal how many times over?
• A mole of soccer fields would cover every square meter of the surface of Mars how many times over?

## A Secret Recipe

Show off your cooking skills, your understanding of a mole and scientific measurements with this fun and tasty project.

• Step 1: Get a simple recipe of one of your favorite cookies that includes the use of baking soda and salt.
• Step 2: Convert the original recipe into moles or particles whenever possible. For example, convert the teaspoons of salt being used into moles of salt in your new secret recipe, or convert the number of teaspoons of baking soda being used into the number particles of baking soda being used.
• Step 3: Convert the original recipe into metric quantities whenever possible. For instance, convert teaspoons of a liquid into mL of that liquid, or convert cups of sugar into grams of sugar.
• Step 5: When someone asks you for the recipe to your amazing cookies, give them a sheet with your new secret recipe so they have to decode it back to a standard recipe before being able to make the cookies themselves!

For added difficulty, you can do the same thing with a pie or cake!
