[SUMMARY] As a result of investigating for elementary school teachers, the percentage of teachers who thought thatthe experiment on“ sunlight and starch” and“ saliva function” was difficult was high. Analyzing the textbooks,various methods have been taken and the methods of these experiments have not been established. Also thechange of nutrients in plants and animals is regarded to use as the development, so children do not understand itsufficiently. Therefore, I conducted the lesson developments to consistently explain from the change of nutrientsto the germination, growth and fruiting for elementary school 6th grade, and to be able to consistently explain thefunctions of plants from nutrient change for second grade of junior high school. Then, I verified its effectiveness.I analyzed the transformation by answering survey questions before and after class. In addition, I created aco - occurrence network by using KH Coder, and objectively analyzed transformations before and after class. Inconclusion, it was demonstrated that it became possible to think about the change of nutrients based on the ideaof transition of grain state.
