Science education has an important role in children's understanding of the world, making the right decisions in accordance with their perceptions, using problem solving skills and scientific attitudes. In this study, the effects of activities prepared by considering the needs of visually impaired students on the development of scientific process skills were analyzed. The case study was used in the study. The sample of the study consisted of one blind and one low vision student. The Science Activity Observation Form (SAOF) was used as the data collection tool. In order to ensure the reliability of the study, SAOF was completed by two researchers and the analysis of the researchers were compared. It has been found that the science activities developed within the scope of the study made a significant contribution to the science process skills of visually impaired students.
