Imprudent behaviour can be encountered in Physics laboratories, where experiments demanding caution are done, as well as in every area of life. It is also well-known that attitude is among the most important factors which affect human behaviour. From this point of view, the aim of the study is to examine whether there is a correlation between pre-service science teachers' tendency for imprudent behaviour and their Physics laboratory attitudes. The sample of the study, in which the survey method was used, consists of 68 first-grade students at Rize University Science Teaching Department in 2010-2011 academic year. As data-gathering tool, Physics Attitude Scale developed by Nuhoglu and Yalcin (2004) and Tendency of Imprudent Behaviour Attitude Scale developed by Aypay (2009) were used. In this study, any statistically significant relations were not found between physics laboratory attitude points and tendency for imprudent behaviour points. (C) 2012 Published by Elsevier Ltd.
