Eclipse Demonstration Working Model

Quick answer: The Eclipse Demonstration Working Model shows how the Sun, Earth and Moon must align to produce a solar or lunar eclipse, letting students see the umbra and penumbra shadows and compare the two eclipse arrangements directly.

Product Description

The LabEquip 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 between solar and lunar eclipse geometry. Exact model dimensions, materials and moving-part mechanism are not stated in this listing; we have not invented these figures and recommend confirming them with our sales team before ordering.

Specifications

Suggested Use

• Position the Moon between the Sun and Earth components to demonstrate a solar eclipse.
• Position Earth between the Sun and Moon components to demonstrate a lunar eclipse.
• Point out the umbra (full shadow) and penumbra (partial shadow) regions in each arrangement.
• Discuss why eclipses do not occur every month, relating this to orbital tilt.

Care & Maintenance

• Handle the Sun, Earth and Moon components carefully to avoid damaging any moving mechanism.
• Keep components clean and free of dust for clear visual demonstration.
• Store the model in a stable location when not in use.
• Check any moving joints or rods periodically for wear.
