Happy mole day!

Tomorrow we will celebrate "Mole day", starting from 6.02 AM till 6.02 PM. In this occasion we can watch the following video "A mole is a unit" wich contains a song of Michael Offutt. If you want to see the lyrics of this song, you can use the next link from the Association for Science Teacher Education. I hope you will enjoy it.
