Eclipse Demonstration Working Model

The eclipse demonstration working model is an educational astronomy apparatus used for showing how the alignment of the Sun, Earth and Moon produces solar and lunar eclipses. It helps teachers and students observe shadow formation, changing celestial positions and eclipse geometry through a controlled classroom demonstration.

Product Description

The STEMAids Eclipse Demonstration Working Model provides a physical representation of the two principal eclipse arrangements. A solar eclipse is demonstrated by positioning the Moon between the Sun and Earth. A lunar eclipse is demonstrated by positioning Earth between the Sun and Moon.

The working format helps learners compare the umbra and penumbra while distinguishing eclipses from ordinary Moon phases. The model’s movement system, illumination source, construction and scale must be confirmed from the approved STEMAids specification.

Key Features

• Dual-eclipse capacity: supports solar and lunar eclipse demonstrations.
• Three-body representation: explains the changing positions of the Sun, Earth and Moon.
• Shadow visualisation: supports instruction on the umbra and penumbra.
• Working activity format: allows alignment to be changed during a lesson.
• Concept clarification: distinguishes eclipses from the regular lunar phase cycle.
• Three-dimensional learning: provides clearer spatial context than a flat diagram.
• Reusable teaching aid: suitable for lessons, astronomy clubs and exhibitions.
• Controlled observation: teaches eclipse principles without direct solar viewing.

How to Use the Eclipse Demonstration Working Model

1. Place the model on a stable surface in a room where shadows are visible.
2. Identify the Sun, Earth and Moon components.
3. Position the Moon between the Sun and Earth to demonstrate a solar eclipse.
4. Observe the Moon’s shadow on the Earth representation.
5. Position Earth between the Sun and Moon to demonstrate a lunar eclipse.
6. Observe the Moon entering Earth’s represented shadow.
7. Change the alignment slightly to compare total and partial coverage.

Safety note: Never look directly at the real Sun or through an optical instrument without certified solar-viewing equipment. Disconnect electrical illumination before adjusting or storing the model.

Care & Maintenance

• Clean the spheres and base with a soft, dry cloth.
• Move orbital arms, gears and joints gently.
• Keep liquids away from lamps and electrical connections.
• Store the model in a dry cabinet away from excessive heat.

Frequently Asked Questions

What is an eclipse demonstration working model used for?

It is used to demonstrate the alignments and shadows that produce solar and lunar eclipses.

What is the difference between a solar and lunar eclipse?

A solar eclipse occurs when the Moon passes between the Sun and Earth. A lunar eclipse occurs when the Moon passes through Earth’s shadow.

What are the umbra and penumbra?

The umbra is the darker central shadow where a light source is fully blocked. The penumbra is the lighter outer region where it is only partly blocked.

Why does an eclipse not occur every month?

The Moon’s orbit is tilted relative to Earth’s orbital plane, so the three bodies are not precisely aligned every month.

Is the model suitable for schools?

Yes. It is suitable for supervised astronomy, geography, Earth science and general science lessons.

Does the model include a working light source?

The illumination configuration has not been verified. Confirm whether a lamp is built in, supplied separately or required from the classroom.
