MHI Employees Teach a Science Class in Hiroshima about Airplanes, Using Paper Models of the Boeing 777


On November 16 and 17, employees of the MHI Group conducted a science class about airplanes for approximately 130 sixth-graders of the Minami-konan Elementary School in Hiroshima. The class was taught using paper models of the Boeing 777.

The proceedings began by introducing the students to the various MHI Group products made at the Hiroshima Machinery Works. Next, the students were informed that the theme of the class was to be one of those products: airplanes, specifically to learn why an airplane is able to fly. The science class then got underway in earnest in cooperation with staff from DIRECTFORCE, a general incorporated association based in Tokyo.

First, the students were given a talk on the history of aircraft and how aircraft are structured. Next, they learned the principles that enable an airplane to fly, aided by an experiment in which they could see and feel air currents created using a hair dryer. After that, the students set to making models of the Boeing 777 out of paper. The completed airplanes were then flown again and again, with the children making gradual improvements to make them fly better. Finally, all the students took part in a competition to see whose airplane could fly farthest. Some students’ planes were even able to fly the entire width of their gymnasium. The serious look on the students' faces as they kept improving their planes was like they were real aircraft designers.

After the class, the students told of their impressions of the experience. "I really became interested in knowing what the MHI Group's business is all about," offered one. "After the easy-to-understand explanations we were given, I was able to understand how an airplane flies," enthused another. "Next time I fly in a plane, I want to watch how the wings and other parts work," said a third.

Going forward, as part of its commitment to making local contributions and educating the next generation, the MHI Group will continue to convey the fun of science to children through monozukuri—the traditional Japanese concept of craftsmanship.
