#FlinnMoleDay

In 2019, one mole was officially defined as containing exactly 6.02214076 x 1023 elementary entities. However, despite this relatively short definition, many students struggle with the concept of the mole and how it relates to amount, mass, and concentration.

Share a video with us of your favorite explanation, analogy, or demonstration showing how you teach students how big a mole is for a chance to receive up to $500 in Visa Gift Cards! After all videos are uploaded, teachers will VOTE on their favorite videos to select the winners. See the full rules here and enter today!

Contest period: The contest runs October 4, 2021 to October 23, 2021. Any entries submitted after October 23 are not valid.  

Prizes will be given to the educators with the most-liked videos as detailed in the official rules at

The submission process is simple, but limited to customers ages 21 and above. Create a short original video sharing the way you teach students how to conceptualize the size of a mole. Videos can feature teachers talking to a camera, non-copyrighted content slides, whiteboard sketches, etc. – use your imagination! Videos cannot feature individuals under the age of 21 and the content should be the video creator’s own idea.  

Next, upload your video to YouTube, Vimeo, or TikTok with the hashtag #FlinnMoleDay and share the link and your entry information on www.flinnsci.com/mole-day-contest.  

Finally, be sure to VOTE for your video and share the page! You may vote once per day.

Content requirements:

  • Video must contain:
    • Reference to 6.02214076×1023, the SI unit known as a Mole.
    • Your concept, method, or reasoning behind how you teach students the size of a mole.
  • Concepts must be original to the entrant and should not be found in any copy-righted material including, but not limited to, text books, digital or written curriculum, science websites, posters, or activities. If material is found to have been copy-righted by anyone outside of the original owner, the video will be removed and the submission will be ineligible for voting.
  • File format: Link to YouTube, Vimeo, or TikTok video
  • Examples of content:
  • How long would it take the entire population of the Earth (assume 6 billion) to collectively count an Avogadro’s number of objects if they could count at the rate of one object per second?
    • (6 × 109 people) × (1 object/persons) × (3 × 107s/yr) = 18 × 1016 objects/year
    • (6.02 × 1023 objects)/(18 × 1016 objects/year) = 3.3 × 106 years or 3,300,000 years
