The need for cooperation between science and mathematics teaching was emphasized by the revision of the national curriculum in 2008. However, a lesson plan which involves cooperation between science and mathematics is rarely performed in the curriculum today. The purpose of this research is to propose a lesson which associates science and mathematics teaching and verify its educational effectiveness in high school. A lesson plan for mathematics class was prepared for 66 high school students, in order to apply Maraldai's angle by inquiring the area of the film stretched across the surface of a soap film, and inside a regular tetrahedron. When Wilcoxon's signed-rank tests were performed on 17 common items in the pre-and post-questionnaires before and after the lesson, significant differences were found in answers, such as "Science is required for mathematics", "By studying mathematics we come to recognize a nature", and "Science and mathematics are subjects which have close relation". These results suggest that there was an clear educational effect in the lesson in which the combination of science and mathematics teaching were practiced.
