Abstract
The utility model provides an experimental instrument used for lunar phase observation in order to solve a problem that teaching demonstration effect is weakened substantially due to lack of a good experimental instrument that can be used for lunar phase observation in middle and primary school physics teaching at present. The experimental instrument used for lunar phase observation includes a pedestal and a rotary plate arranged on the pedestal. An earth simulating ball is arranged in the center of the rotary plate. The edge of the rotary plate is provided with a moon simulating ball rotating along with the rotary plate. A light emitting source is arranged on the pedestal and on a side of the rotary plate. The earth simulating ball is provided with a camera. The camera is connected with a video output device.
