The Phases of the Moon Working Model is an interactive educational apparatus designed to demonstrate the changing appearance of the Moon as seen from Earth. Built on a strong metal base, the model ensures stability, durability, and repeated classroom use.
The model consists of a central light source representing the Sun, a fixed Earth model, and a revolving Moon model mounted on a mechanical arm. As the Moon revolves around the Earth, different portions of its illuminated surface become visible, accurately demonstrating the lunar phases.
How the Model Demonstrates Moon Phases
The model clearly shows the sequential phases of the Moon, including:
• New Moon
• Waxing Crescent
• First Quarter
• Waxing Gibbous
• Full Moon
• Waning Gibbous
• Last Quarter
• Waning Crescent
As the Moon completes one full revolution around the Earth (approximately 28 days), students can visually observe how the relative positions of the Sun, Earth, and Moon create each phase.
Key Features:
• Working model demonstrating all lunar phases
• Strong and stable metal base
• Smooth mechanical movement
• Accurate Sun–Earth–Moon alignment
• Clear visual representation of illumination and shadow
Educational Use:
• Helps understand lunar cycle and phase sequence
• Explains why the Moon appears to change shape
• Ideal for STEM education, classrooms, and science exhibitions
