According to the results of a questionnaire in the Trends in International Mathematics and Science Study (TIMSS) conducted in 2011 by the International Association for the Evaluation of Educational Achievement (IEA), high school students in Japan do not realize the significance and usefulness of learning science. Many events on science education targeting high school students have been held in an attempt to solve this problem. At the events, various scientific experiments are introduced to attract the interest of students to science subjects or science technology. In this study, the taste sensor, which is used in the food industry and pharmaceutical industry, is considered as a science teaching material. We fabricated a new taste sensor for educational purposes that satisfies the requirements of safety and fabrication time for science teaching materials. In a basic experiment, the results correspond to the response of human taste, which also shows logarithmic changes. In an experiment demonstrating an application of the taste sensor, the results mean that the taste sensor fabricated for education can measure the intensity of saltiness and sourness in a beverage. Thus, it was indicated that the taste sensor fabricated for education is a useful science teaching material.
