The purpose of this study is to investigate the elementary preservice teachers' conceptions about 'plastics' focusing on non-polar property from a National University of Education. For the study, the views about plastics, relative shapes of a water droplet on plastic or glass material, and relative shapes of water surface in the plastic or glass measuring cylinder were surveyed from the preservice teachers. And the responses were analyzed based on the patterns. The results from the study are as follows: First, most preservice teachers were well aware of the plastic products which are used in daily life. Second, the responses concerning the reason why plastics can be used commonly were divided into 2 categories with 14 sub-level groups. However relatively few preservice teachers mentioned regarding ‘chemical stability’ and ‘conductivity’, which are associated with the plastics’ non-polar property. Third, it was found that 50 participants (30.1%) had ‘Scientific conception (Sc)’, 38 (22.9%) had ‘Partial-scientific conception (Ps)’, 66 (39.8%) had ‘Misconception (Mc)’, and 12 (7.2%) had ‘No conception (Nc)’ on the subject of the relative shapes of a water droplet. Fourth, the distribution patterns and the ratio of the preservice teachers’ conception on the survey question 3 concerning the relative shapes of water surface were quite similar to those of the survey question 2. So it was concluded that overall understanding level of the preservice teachers was pretty low on the subjects of the relative polarities of the plastic, glass, and water as well as their interactions. Fifth, the distribution percentile of ‘Sc’/‘Ps’/‘Mc’/‘Nc’ was not related with the gender but highly correlated with preservice teachers’ academic field and their science subjects taken in high school. Based on the results from the study, some educational guidelines were suggested.
