# 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:

 Example: 1D60.10.a Howitzer and Tunnel (another name, Ballistic Cart and Bridge) attachment:piralogo.jpg 1 Area (mechanics) attachment:bucky_left_2c.gif D Topic (motion in two dimensions) 60 Concept (projectile motion) .10 Demonstration (Howitzer and Tunnel) For more info Click [http://physicslearning.colorado.edu/PiraHome/dcs/PIRADCS.html DCS] .a Duplication UW-Madison addition for multiple units, (a, b, c, ...)
