The Changwon Plant hosted the “Junior Engineering Class” at Naedong Elementary School that many executive and staff members’ children attended from April 9th to 18th. Eight members participated as one-day teachers, and had a class with the “secret of airplane wings” subject for 5~6 graders, allowing students to make a model airplane with a solar heat sensor power source and learn two basic principles of aerodynamics, lift and drag. Since 2004, Changwon Plant has conducted the Junior Engineering Class and it has been well-received by students and the school.
