The Lower Merion High School chemistry department recently continued their tradition of celebrating "Mole Day" with a lab exploring the relationship between circumference vs. diameter and the value of pi. Celebrated annually on October 23 from 6:02 a.m. to 6:02 p.m., Mole Day commemorates Avogadro's Number (6.02 × 1023), which is a basic measuring unit in chemistry.
Students brought in canned food to use during the lab, which will be donated to those-in-need at the Ardmore Food Pantry. The circular tin cans helped to demonstrate how the circumference divided by the diameter produces the same value regardless of their radius. This value (pi) is the ratio of the circumference of a circle to its diameter. To view a slideshow of pictures of the students in action on Mole Day, click on the image below.
