Kinetic Molecular Theory from a Jukebox

When the authors first heard "The Witch Doctor's Song" hlsring from the Student Center they were somewhat impressed with the intricacy of the lyrics which seemed to he something like, "Ooh, eeh, ooh ah ah, ting, tang, wsllah wallah hing hang," with additions and variations. But more impressive was the way the student body learned the complicated syllables almost effortlessly. The idea of using music as a common basis of communication presented itself, and although perhaps men to criticism became of the effect on orofessorial dienitv. the method mav he defensible from the standpoint of pedagogical results.

The three states of matter and the msociclted motions of the physical speclea are described to the class in terms of the following analogies: The gaseous state. Rock and Roll. Jazz. Wild gyrations, rapid random movement. Violent

action of molecules with great spaces between molecular centers. The l ipid stote. Waltzes, Ballads. Dreamy swing music. Plenty of movement but ofs.

more subdued nature. The whole dance floor constantly changing pattern hut much less space between moleeules. Characterized by fluidity of the group and ahility to t~ccommodate to either large ballrooms or intimate cozy nooks, hut always in motion! The solid slate. Foot patters. Observers. Chaperons who pick out a comfortable spot and

relax for the evening, tapping their feet gently. Movement, but around a much more restricted vicinity, and both observers and chaperons packed very closely together in a crowded observation area, leaving the open spaces for the dancers.

The response of students in general chemistry, physical science, and general physics classes to these analogies has been excellent. Easy recall serves as a basis for satisfactory extension to more advanced concepts.
