The main purpose of this study was to investigate how the preservice elementary school teachers recognize body length of microorganisms in water, by using the questionnaires to ask total length of Oryzias latipes and relative length of microorganisms (Daphnia pulex, Paramecium caudatum). The findings of this study were following: 1) the preservice elementary school teachers’ recognition of body length of microorganisms is lower than relative length of microorganisms; 2) the preservice elementary school teachers had several preconceptions related to body length of microorganisms. Based on those findings, the preservice elementary school teachers should be planed reconstructing pre-conception and progressing scientifically understanding of microorganisms by comparing the body length of microorganisms through learning activity to perform microscopy of a variety of microorganisms.
