This paper proposes a teaching method for experiments and observational learning in elementary science classes that will improve children's emotions towards such learning activities. In the proposed method, children record digital video clips of the subjects prepared by themselves, using a video clip generation system connected to network cameras. The system enables students to continuously record and monitor their subjects in various environments. The authors conducted researches in two units of science classes in an elementary school. The first research was conducted to examine the effectiveness of observational learning using video clips that continuously recorded subjects by network cameras. The second research was conducted to examine the effects on children of continuous observation of the subjects which they prepared by themselves. The results showed that significant effects were observed in children's emotional dimensions such as fulfillment towards learning ; active attitude ; and motivation in observational learning when the method and the system were introduced in the lecture. Children highly evaluated their understanding of what they learned. In the post-interviews, some children who watched video clips of their subjects told that they felt comfortable and productive during their learning because of the authentic nature and controllability of the observation.
