How Big is a Mole? Have your students to this as a project or an activity in class where they take their favorite item, (a soccer ball, a lipstick, a candy bar) and compare it to something massive, (a planet, an Olympic pool, the circumference of Earth) to realize how big a mole actually is. You can make this as detailed or as simple as you like. I usually do this as a project (which I grade as a take home test), but this could easily be done in a classroom where students have devices and can search the size of a soccer ball for instance.
This will use dimensional analysis/factor label method, along with the conceptual understanding of a mole, the atom and their sizes.
The document is a Word Document which you can edit to your liking. I have provided examples such as a Poster, Mole Manipulative or Decorate a Tissue Box (I usually give some extra credit for the "donation" to the classroom).
I've also included a small poster than can be placed on a bulletin board, if this is something you'd like to share with your school/community.
