This study aimed to explore alignments among three curricula based on the contents of the university level curriculum. The 2015 revised curriculum, International Baccalaureate(IB), and Next Generation Science Standards(NGSS) were selected for this study, and a college textbook was analyzed to compare the curricula. As the age groups studying the curricular were different, we reorganized them according to school ages prior to conducting the study. The results of the analysis were: first, the contents of the 2015 revised curriculum did not sufficiently elaborate on the natural hazards related to humans, unlike the university level, IB PYP, and NGSS curricula. Third, there are different ways of introducing scientific vocabulary curricula, meaning that the number of scientific vocabularies in the 2015 revised curriculum was less than that in the IB, PYP, and NGSS.
