Many elementary school students have a very low understanding of their concepts, this is because students do not absorb learning well, one of the factors is the lack of learning media. Therefore, it is necessary to use more interactive learning media such as animated video media. This study aims to determine the effect of animated video media on students' understanding of science concepts. This research was conducted at SDN Kebon Besar 1 with the method used in this study, namely quantitative experiments (Quasi Experiments). The population used in this study were all grade IV totaling 56 students, students were divided into 2 groups, class IV A as the Control class using conventional learning methods and class IV B as the experimental class using animated videos. The data collection technique was in the form of a test (pretest-posttest). This is based on the results of the hypothesis test carried out by testing the t-test on the posttest test with a significance level < (α = 0.05). To strengthen the results, the t-count value is known to be (7.537) with Sig. (2-tailed) = 0.000 which means H0 is rejected and H1 is accepted. It can be concluded that animated video media has an influence on students' understanding of science concepts.
