Goals: Today, much emphasis is placed on the application of the flipped method in the teaching of various experimental sciences. Despite this emphasis, there is not much research evidence to support it. This study examines the impact of the use of flipped methods, collaboration, exploration, and lecturing on the experimental science learning of sixth grade elementary school students. Method: The current research is applied in terms of purpose and quantitative approach, which was performed on a quasi-experimental basis using four groups with pre-test and post-test with the control group. The statistical population was the sixth grade classes of boys 'primary schools in Neishabour city. In this study, 40 students from four classes in boys' primary in the city of Neyshabour, whose teachers were purposefully selected, participated. In each school, ten sixth-graders with moderate intelligence were selected according to the teachers. The experimental groups were trained using exploratory, collaborative and reverse teaching methods, and the control group was trained by lecturing in Five 45-minute sessions using designed protocols. It should be noted that two sessions were dedicated to teacher training for the proper implementation of educational protocols. The duration of this course was five weeks and the content of that ninth chapter was the topic of the Energy Science textbook. Data collection tools included designed teaching protocols in collaborative, reverse and exploratory methods, and pre-test and post-test forms, each with ten questions, the validity of which was examined using teachers' opinions. To analyze statistical data, descriptive statistics indicators(mean and standard deviation) and inferential statistics(one-way analysis of variance, analysis of covariance and for significant differences between groups, Toki follow-up test) were used. Regarding the research questions, the results showed that there is a significant difference between the methods of reverse teaching, exploration, cooperation and lecturing in the learning of sixth grade elementary students in the field of experimental science energy. Findings: there is a significant difference between the effect of the flipped method and the effect of other methods. This study suggests the use of flipped teaching methods to teach various topics along with other methods such as collaboration and exploration for experimental science lessons. Conclusions: Generally, the results showed a significant increase in the flipped teaching method compared to other methods. Also, the collaborative method had a greater impact on the learning rate of experimental sciences than the exploration and lecture method.
