This article addresses measurement of atmospheric surface pressure using economical instruments. It is intended to provide members of the Society with a ready reference to respond to inquiries from earth and physical science teachers at the junior and senior high school levels. We describe various types of barometers, discuss observing techniques, present our experiences with a selection of commercially available pressure-measuring equipment, and discuss simple experiments illustrating effects of atmospheric pressure. To assist members in advising teachers interested in meteorology as part of the science curriculum, a few suggestions for student and class projects are included.
