In order to create an awareness in school of the association between science and technology with daily life, daily necessities were employed as learning subjects. This study created such an awareness in high school students by using disposable diapers as an example of a daily necessity. In this lesson, each student was first asked to indicate a preference for either hydrophilic or hydrophobic lining for the diaper, and then to prepare two diapers using hydrophilic or hydrophobic lining,water-absorbent padding and backing.A Iarge percentage of studentsexpressed the common assumption that since hydrophilic materials were suitable for fabrics contacting the skin they were also suitable for the lining of diapers. However, after a measured quantity of water was poured onto the two diapers and the two linings were compared by touch, the students recognised their misconception. They also observed that the water absorption rate of commercial diapers was much faster than those of their own making, illustrating the absorption mechanism. Thus they learned that many aspects of science and technology taught in school, such as capillary action and super absorbent polymer to soak up large amounts of water, were employed in the production of disposable diapers which they had formerly regarded simply as paper and cotton pulp. This research should enable us to recognize the need to adopt as learning subjects objects in the daily livers of the learners.
