The Lecture Demonstration Facility exists to aid in the teaching of physics and astronomy to undergraduate and graduate students in the field of physics and astronomy, as well as non-majors taking physics and astronomy here on campus.
PIRA or Physics Instructional Resource Association
The Physics Instructional Resource Association exists to serve the needs of Physics Instructional Support Professionals through sharing ideas about demonstrations, laboratory activities, learning centers, and instructional resources in general. The PIRA organization has been in effect since 1985 and was created to aid Physics Teachers with demonstration and laboratory information. We encourage all teachers of all levels to join our organization and use the resources available. These resources include, but are not limited to...
- Demonstration Classification Scheme (DCS)
- the top 200 demonstrations we recommend (PIRA 200)
- searchable database of multiple physics lecture demonstration websites at once
- email listserv (TAP-L)
PIRA (see below) has developed a Demonstration Classification Scheme (DCS), which allows members to organize and acquire reference material for physics demonstrations. Each demonstration is assigned a specific number and is placed into the area where they are most used. These areas include Mechanics, Fluid Mechanics, Oscillations and Waves, Thermodynamics, Electricity and Magnetism, Optics, Modern Physics, Astronomy, and Equipment. The structure of the classification system is shown in this example:
|howitzer & tunnel (different people uses different titles)
1D60.10 (one specific number for everyone)
1 = mechanics
1D = motion in two dimension
1D60 = projectile motion
1D60.10 = this specific demo
The topic and concept divisions of the structure loosely follow standard textbook organization of chapter and section. They were created to organize existing demonstrations, not cover the entirety of elementary physics, and therefore they skip some areas of the curriculum covered by standard textbooks. The standard curriculum has changed over the years and categories have been created to contain the many demonstrations rendered obsolete by modern textbooks.
