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) | ||
