Mole Day is a "national" celebration of chemistry and education
that is an ideal time to engage families with the science educational
process. It is observed from 6:02 am to 6:02 pm on October 23rd (6:02,
10/23). Why? The mole is a unit of measurement based on work done almost
200 years ago by Amadeo Avogadro as he studied gas behavior. His work
led to the association of a number – 6.02 x 1023 – with the
mole. Similar to the dozen, a mole is a unit of matter that allows particles
to be "counted." The major difference between the mole and the
dozen is that the mole is much bigger!
Through the activities presented in this lesson, students will become
familiar with the mole concept and develop memory pathways for recalling
key ideas associated with this magnanimous quantity. Additionally, students
and families will be provided online resources for checking their understanding
of the content.
Students will be able to:
 Recognize methods used to define the mole
 Convert various quantities to the mole
 Provide a context for understanding the usefulness of scientific
notation and the mole

MST Standard 3, Key Idea 2
Students will understand mathematics and become mathematically confident
by communicating and reasoning mathematically, by applying mathematics
in realworld settings, and by solving problems through the integrated
study of number systems, geometry, algebra, data analysis, probability,
and trigonometry.
MST Standard 4, Key Idea 3
Students will understand and apply scientific concepts, principles, and
theories pertaining to the physical setting and living environment and
recognize the historical development of ideas in science. Students explain
the properties of materials in terms of the arrangement and properties
of the atoms that compose them.

http://college.hmco.com/chemistry/general/zumdahl/world_of_chem/1e/ students/flashcards/ch06/index.html
This textbook companion site generates 7 flashcards to review molerelated
concepts. The cards can be printed and cut out or played online. If
played online, students can shuffle the pack and/or "check off"
terms already learned to prevent redundancy; students may view all cards
or just those cards that they have not learned. Terms are shown on one
side, and definitions are displayed on the reverse side, which is activated
by a "flip" command. "Rapid review" allows students
to view terms and definitions simultaneously. This site requires the
Shockwave plugin, available online at http://www.macromedia.com.

Three levels of "WhackaMole" played similarly to the arcade
game are available on this site. Players get five misses before the
game is over. This page is maintained by Teach Learn and Communicate
(TLC) Center for elementary students. Links to geography, math, and
English pages abound. Additionally, learners can visit several nations
from the Alfy.com homepage on a virtual arcade tour to Korea, Taiwan,
China, Portugal, or Israel.
