We are engaged in educational activities for scientific manufacturing to contribute to the development of human resources for regional innovation. In order to convey the experience of scientific manufacturing without leaving anyone behind in such a vast area as Hokkaido, it is essential to conduct online lectures and workshops using ICT such as video teleconferencing systems. In this paper, we introduce the system and the method of the lectures, and the device to make the lecture easy to understand for children. From the results of the questionnaires, they shown that it was possible to conduct the online lecture with high satisfaction by making the participants experience a sense of achievement with moderate difficulty. On the other hand, it also revealed some issues for the future, such as the consideration of content that will further attract children who are not satisfied or have little interest in it.
