Abstract
A phono-optic windmilling celestial globe is used for geography teaching, including: a transparent housing of celestial globe which is a transparent and hollow sphere drew with cosmos asterism pattern. The centre of sphere fixed connects with a Earth model via a transmission shaft, an indicating light cluster fixed connects with inner surface of the transparent housing corresponding with cosmos asterism pattern. A pedestal of the celestial globe connects to lower part of the transparent housing, upper part of the transmission shaft live connects with coping of the transparent housing, lower part of the transmission shaft connects to upper chord rotator of pedestal which with a upper chord hand. The vivid and viacacious utility model has simple structure. When used in teaching, light cluster blink as fixed star. The Earth model in center is revolved by the upper chord rotator of pedestal while indicating light cluster are blinking. Then students observe why sun arising from east and down west and easy understand reason of direction of Earth rotation from east to west.
