The purpose of this event is to provide an opportunity for elementary school students to communicate with the curators of the Science Museum and feel closer to science while spending time in after-school childcare on weekdays. The Hamamatsu Science Museum "Miraira" and the after-school children's association in Hamamatsu City were connected via online broadcast, and a science experiment workshop was held using familiar materials such as paper cups and aluminum foil. In 2019, we were entrusted with the renovation of the Hamamatsu Science Museum using the DBO method, which integrates design, construction, and operation. The Company operates the operation jointly with SBS Promotions as the "Designated Administrator". * DBO method (Design, Build, Operate): A method of public-private partnership in which design, construction, maintenance, and operation are comprehensively ordered to private companies.
