PIRA Classification Scheme
"PIRA" stands for the Physics Instructional Resource Association, partially supported by the American Association of Physics Teachers. Join the [http://www.aapt.org AAPT!]
The goal of the PIRA Demonstration Classification Scheme was created to provide a logical organization and universally inclusive unique number to every lecture demonstration nation wide. The structure of the classification system is as follows:
