The aim of this research was to provide preschool children with context-based science and nature activities and basic process skills. The research was carried out with 11 children aged 48-60 months in the second term of the 2019-2020 academic years. The research was designed according to action research, one of the qualitative research designs. In the research, context-based science and nature activities planned by the researcher were applied. The Basic process skills Scale for Preschool Students, observation, interview, and diary were used as data collection tools. As a result of the study, it was determined that science and nature activities developed based on context-based learning are effective in gaining basic process skills in preschool. From this point of view, it can be recommended to implement activities suitable for context-based learning in different environments. Preschool teachers who want to gain basic process skills can be recommended to use context science and nature activities.
