Using a surplus of older laboratory instruments, 48 students in a learning and behavior course completed an assignment designed to provide an introduction to the history and use of some instruments in psychology. Students worked in pairs, were assigned one instrument, and created labels in which they identified several keys characteristics of an instrument. Assessments indicated that students learned from and also enjoyed this assignment. Sixteen of the 48 students presented and demonstrated each instrument to 19 students enrolled in a history and systems class. Pre- and posttest assessments in the history and systems class indicated significant increases in knowledge about these instruments. This is a simple, versatile activity than can be used in a variety of psychology courses.
