Earth Science of the Olympics Freebie

Another Freebie!! 
Similar to last week, but that one was a big success, so hopefully some people will enjoy this.
Last week I posted a "Science of Football and Olympics" in honor of the Superbowl.  It was focused on biology and life science topics.  
Here is one for this week focused on the Olympics, but focused more on Earth Science topics.  I hope you enjoy!  This is a great way to work in Common Core, relevancy, and grab students' interest
Science of the Olympics Hope you are having fun watching the Olympics.
And I promise some posts of more substance coming soon....some things are in the works here!
