We, the Science Group (Department of Natural Science, National Institute of Technology, Kisarazu College), have been involved in various community contribution activities over 25 years to solve the problem of children's lack of interest in science. During the activities, a great deal of content for science education has been developed. The activities were stalled for some time due to COVID-19, but have been positively resumed since 2023. The purpose of this report is to give a proper summary of our previous activities and the various contents, which applies them to future activities.
