This research focuses on an experiment in boiling water in grade 4 Japanese elementary school science class. A questionnaire answered by 111 Japanese school teachers revealed that only few teachers understood that the cooler air around the thermometer prevents it from reaching the exact boiling point of water. Teachers want the children to obtain the boiling point of water at 100°C, yet in actual experiments it is difficult to measure it precisely. In order to avoid this situation in the classroom, it is necessary for the teacher to understand the characteristics of and master the rod thermometer.
