This thesis investigates the lesson methods of teachers for deepening the value of the respect for life. We analyzed the questions from the teachers and the children's responses in a morality lesson for fifth grade elementary school students, clarifying a method for deepening the children's thoughts. As a result, the following three points were clarified. The first was to have the students find questions during the class. It was shown that, instead of having the teacher prepare questions in advance, having the students find questions and try to solve them on their own gave the students the attitude to think on their own. The second was to give the students a method for thinking. It was shown that by giving the students a method for comparing the changes in thoughts and a method for finding the differences between the main character and the people around them, they can learn autonomous thinking. The third was to deepen the teacher's outlook on human life. Deepening the understanding of human life wherein one both shows human vulnerability yet tries to live proudly gives depth to the research of teaching materials and lesson composition. It was shown that this kind of teacher stance deepens the children's thoughts.
