The current study investigated which dimensions of scientific process are capitalized on by elementary school third graders to explain the concept of science at conceptual level. The study was conducted by using "Basic Qualitative Research", one of the qualitative research approaches with the participation of 225 elementary school third graders. Totally 46 codes used by the students to explain the concept of science were formed and these codes were classified under seven themes. At the end of the study, it was concluded that the students mostly used the codes classified under the theme of scientific process to explain the concept of science. The findings of the study are believed to make some important contributions to the development of the teaching program of the Science Course to be given to elementary school third grade as of 2014-2015 school year and to the implementation of this program by eliciting the current state of students.
