| Research Abstract |
Aimed at manufacturing education, environmental education, and welfare support, a hand-made color comparator using waste plastic cups is proposed. Unlike conventional color comparators, the proposed comparator is realized by cascading three waste plastic cups. Therefore, teachers can perform environmental education not only by a water quality test but also by reuse of plastic wastes. Furthermore, by covering the color comparator with paper clay, students can make a color comparator without soldering. The validity of circuit design is confirmed by experimental classes. The experiments show that 1.students can learn the basic of electricity, reuse, and manufacturing and 2.even the students with color-blindness can receive environmental education such as a water quality test by using the proposed color comparator.
