This study aims to conduct a multidimensional analysis of the 2017 Science Curriculum taking the previous three curricula into account. The document analysis technique, which is a qualitative research method, was used. The Science curricula of 2000, 2005, 2013 and 2017 were analyzed in detail for this purpose. The 2017 Science Curriculum, which is one of the last four curricula, was described and interpreted by discussing its important qualities as well as the similarities and differences between this curriculum and the other curricula. In addition, it was found out that the Science curricula used between 2000 and 2017 were in line with the Ohio Competency-Based Science Model. The skills included in these four curricula, the contents used to have skills acquired, the materials used to equip students with the skills, and the conditions where the acquisitions are expected to be used are pointed out in this study taking into account the key elements included in the Competency-Based Science Model. We think that the findings of this study are important as they reveal the general points of view and consistency of the curricula rather than showing their superiorities or shortcomings in relation to each other.
