Abstract
It was the aim of this study to clarify the typical characteristic of elementary school curriculum especially in science class in New Zealand. In order to attain the aim the authors collected the data by doing an on-the-spot investigation. The data capable of collecting were also taken from "Science Syllabus and Guide" and "Science Resource Unit". They were officially published by Ministry of Education of New Zealand. One of analyses used was considered a new attempt to use the graph theory. Using the method, the structure of the curriculum could be "pictured" in such a way that the vertices represent the teaching units and the conceptual relationship between the two units indicated by an edge between the appropriate vertices. The results of analyses were as follows: 1. No textbook was used in science class in elementary school. 2. As planning teaching schedule, teachers could select Units and arrange them of their own free will from Science Resource Unit. 3. The structure of Science Resource Unit has been seen to have become complicated gradually according to the increase of age when children learn them.
