In an attempt to give students practical scientific knowledge and increase students' interest in science, Kisarazu Daiichi Junior High School has instituted the practice of inviting professors from Kisarazu National College of Technology to bring hands-on activities to its science classes. The ongoing guest teacher program requires JHS students to put the scientific theories they have learned into practice through the construction of simple scientific devices. Students are taught chief engineering principles and gain the opportunity to use tools and instruments to which they do not have access in ordinary science lessons. Learning through direct experience cultivates students' curiosity of nature world and gives them to a fresh impression of scientific theories of science and technology in their lives.
