In 2016, we conducted a survey of high school students regarding science classes, and found that the percentage of high school students who answered that they "like science" or "science is important" was lower than for other subjects. However, more than 80% of elementary and junior high school students answered that they ``like experiments and observations.'' Additionally, a 2019 smartphone penetration rate survey found that approximately 90% of students use smartphones. Additionally, recent advances in VR technology have been remarkable. Based on the above, I thought that creating a simulation app using VR technology using smartphones could change the way high school students think about science classes. In this paper, we developed a new simulation application for science experiments. The subjects were asked to experience the newly created app and answer a questionnaire. The average score was 4 out of 5, which was poor. However, a problem was also discovered at the same time. The problem is that this app is a simulation app, so the user experience is not very good, so I would like to develop an app that is a little more user-friendly in the future. I would like to create apps for other fields while improving the problem.
