We receive much benefit from the sun every day. But many high school students can’t imagine a movement of the shadow created by the sunlight. Student’s knowledge and recognition of a space figure are needed in science education at an elementary and a junior high school. However the contents of the math education nowadays are insufficient though they become the bases of science education. Therefore, in this paper we aimed that students obtain structural understanding of a movement of the sun through the practical lesson which is based on the fact that the locus of the shadow becomes a conic curve. Moreover we consider its validity as a teaching material of the space figure education for the students.
