Station 1:
Take some measurements and Calculate PI:
Arguably the most famous number that is not an integer, pi comes from dividing the distance around a circle by the greatest distance across the circle:  circumference divided by diameter. 

This quotient or ratio equals the number pi no matter how big the circle is.  Even though this relationship has been known for thousands of years, it was only 300 years ago that the Greek letter pi (the first letter of the Greek word for “surrounding perimeter”) was introduced.  This number has a decimal representation which never stops or repeats, although modern computers have now computed pi to over a trillion decimal places!

See how close you can come to p!
