The study was carried out with the quasi-experimental design of quantitative research methods and an approach in which pretest and posttest applications were applied to the experimental and control groups. The research sample consists of 72 fifth grade students, 36 of whom are in the experimental group and 36 in the control group. Data collection tools included an academic achievement test and an attitude scale regarding learning science. The collected data were analyzed with the SPSS package program.
