This article addresses the measurement of temperature using easily fabricated and/or economical instruments. It describes techniques for measuring temperature with simple instrumentation, comments on our experiences in implementing the techniques, and provides a list appropriate references. The intent is to provide members of the Society with a ready reference to be used to respond to inquiries from earth and physical science teachers at the junior and senior high school level. The material should aid members who are interested in pursuing the educational initiatives described in Weather Education (Royal Meteorological Society, 1984) and in the AMS Guide to Establishing School and Public Educational Activities (American Meteorological Society, 1985). To assist members in advising teachers interested in including meteorology in science curricula, we will also include a few suggestions for student or class projects. Good references concerning meteorological observations and measurements in schools are the books by Trowbridge (1973) and Couchman et al. (1977), and the pamphlets by Geer (1975), Pedgley (1980) and the National Oceanic and Atmospheric Administration (1979). The review articles by Mazzarella (1985) and Brock (1985) contain much useful information, as do the handbooks by the Meteorological Office (1981) and United States Department of Agriculture (1976).
