The moon phase demonstration instrument is composed of earth model, moon model, gear, size turntable and base. Through the black and white side of the moon model to simulate the light and dark side caused by sunlight on the moon, turn the small turntable counterclockwise, the moon model will rotate around the Earth model, and at the same time, driven by the gear, the moon model will produce rotation, simulating the moon phase at different times.
