The purpose of the current study was to investigate pre-service chemistry teachers' knowledge about chemistry laboratory equipments and their functions. The sample of this study consisted of eight pre-service chemistry teachers. Open-ended questions were used in this study. The findings of this study showed that most of the participants mentioned the erlenmeyer and thermometer as laboratory equipments when they were asked to write the equipments that they remembered. Additionally, it was seen that participants had difficulties in explaining the function of the equipments. This study concluded that pre-service chemistry teachers did not identify laboratory equipments and know their functions appropriately. (C) 2011 Published by Elsevier Ltd.
