要 旨 ： We investigated the light pollution by observing stars at the night sky in Sakuragaoka junior high school and Sendai city. The environmental investigation in two different scales indicates that the difference of the scale of environmental recognition provides a different aspect of environmental targets. In the investigation in the school district, the viewpoint is based on the ground; however, in the investigation in Sendai city, the viewpoint becomes bird’s-eye view. This environmental program can become one of the good teaching materials to promote an environmental recognition by different scale.
