In the Department of Studies of Lifestyle Management at Jissen Women’s University, undergraduate students can learn about environmental science and energy. The introductory course on environmental science is offered to first-year undergraduates. In this course, the electromagnetic waves, such as visible, infrared and ultraviolet rays, are taught from through the phenomenon of aurora. It was found that the use of teaching materials with many photographs and graphs are very effective for the undergraduates. The positive attitude of the undergraduates in studying environmental science and energy was enhanced by the creation of an ecological campus map and growing the KANTO Taraxacum (a dandelion that grows naturally in the Kanto region of Japan).
