要　旨　：　We have developed a teaching aid of night sky environmental researches. With this aid, students can understand light pollutions in the viewpoint of the environmental education. We discuss how light pollutions can be treated as one of the environmental educations, and then we introduce two night scenery illustrations in the same town, but with different light conditions. Students compare both illustrations and find out the environmental differences in the viewpoint of light pollutions. Effect of the environmental education using this aid in the elementary and junior high schools are also discussed.
