Solar & Lunar Eclipse Manual Model STEM Lab Manufacturer,Supplier and Exporter in India
Product Code : SCL-OS-12465
The Solar & Lunar Eclipse Manual Model STEM Lab is a premier educational tool designed to bring the wonders of astronomy into the classroom. Manufactured by Educational Instrument India, this model provides a tangible, 3D representation of the celestial alignment required for eclipses. By transitioning from abstract diagrams to a physical, gear-driven model, students gain a profound understanding of the Umbra, Penumbra, and orbital nodes.
Why Educational Instrument India?
With decades of expertise in laboratory manufacturing, Educational Instrument India is a trusted name for high-quality, durable, and curriculum-aligned apparatus. Our models are specifically designed to withstand heavy classroom use while maintaining scientific precision, making them the preferred choice for educators across India and abroad.
Product Description
This STEM Lab model features a synchronized mechanical system that represents the Sun, Earth, and Moon. The Sun is represented by a powerful, diffused light source, while the Earth and Moon are scaled spheres mounted on rotating arms.
Through manual gear operation, students can simulate the Moon’s orbit around the Earth and the Earth’s orbit around the Sun. This allows for the clear demonstration of:
Solar Eclipses: When the Moon passes between the Sun and Earth, casting a shadow on Earth.
Lunar Eclipses: When the Earth passes between the Sun and Moon, casting a shadow on the Moon.
Partial vs. Total Eclipses: Understanding shadow density and positioning.

How to Use the Model
Setup: Place the model on a flat laboratory table and ensure the light source (Sun) is directed toward the Earth-Moon system.
Solar Eclipse Demo: Rotate the manual arm until the Moon is positioned directly between the Sun and the Earth. Observe the small shadow (Umbra) falling on a specific part of the Earth.
Lunar Eclipse Demo: Continue the rotation until the Earth is positioned between the Sun and the Moon. Observe how the Earth’s larger shadow completely or partially obscures the Moon.
Angle Adjustment: Use the adjustable orbital plane to show why eclipses do not occur every month (illustrating the 5-degree tilt of the Moon's orbit).
Observation: Use the provided viewing screen to see the "shadow phases" more clearly in a darkened room.
Frequently Asked Questions (FAQ)
Q1: Can this model be used for Class 10 and Class 12 Geography?
A: Yes, it is perfectly aligned with NCERT, ICSE, and IB curricula for middle and high school students to explain complex celestial alignments.
Q2: Is the LED light replaceable?
A: Yes, the high-durability LED is designed for 10,000+ hours of use but can be easily replaced if necessary.
Q3: Does the model require a dark room to work?
A: While it works in standard classroom lighting, the shadows (Umbra and Penumbra) are most visible and impactful in a semi-darkened environment.
Q4: Is the manual rotation difficult for younger children?
A: Not at all. The gear ratio is designed for smooth, low-effort rotation suitable for students aged 8 and up.
