Scientific craft club was held in an elementary school. The club started, 5 years ago, by my daughter’s request. About 8 to 10 times of classes were held in a year. I choose each theme of crafts from engineering view, that is, not to verify scientific phenomena, but to manufacture useable apparatus using scientific principles. Paper plane, Leeuwenhoek’s single lens microscope, magnetic slime, pan flute, post scale, polygon kaleidoscope, and electric music box were made in the last year.
