Presented are descriptions (with photographs) of demonstration equipment purchased, assembled, developed, and used at William Jewell College (Missouri) during the past 25 years. The descriptions are organized into the following topic areas: (1) mechanics; (2) heat; (3) waves, sound, and acoustics; (4) electricity; (5) optics; and (6) atomic and nuclear physics. This arrangement follows closely the freshmen-level text by Harvey E. White ("Modern College Physics") and is related to the sophomore-level text by F. M. Sears and M. W. Zemansky ("University Physics"). However, many of the demonstrations presented may be used with any one of the good freshmen/sophomore-level college physics textbooks currently available. (JN)
