The sun's annual path in the sky
Audio Guide：
The Earth rotates on a slightly tilted axis as it revolves around the sun, so light from the sun strikes directly at different latitudes in different months. This also means that different latitudes see the sun take a different path through the sky, and that the length of daylight differs with both the season and the latitude.
Exhibit Introduction：
Simulate the path of the sun's apparent daily motion and let the visitors know that the location of sunrise and sunset were seen from the earth change according to different latitudes and different seasons.
