Sun-Earth-Moon Model
Product Code : SCL-PL-12303
Sun-Earth-Moon Model (SKU SCL-PL-12303), also called a tellurion, is a geared model that reproduces the movements of the Earth and the Moon so that students can see how they relate to the Sun. Science and geography teachers use it to explain seasons, day and night, Moon phases and eclipses in middle and secondary school. Science Lab Supplies, a science apparatus manufacturer in India, builds the model at its factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and sells it directly to schools, colleges, tender contractors and distributors.
Specifications
The model works through a set of gears that faithfully reproduces the motions of the Earth and the Moon, so one demonstration can move from day-night alternation to seasonal change, the lunar cycle and the positions that produce solar and lunar eclipses. Key facts are listed below.

Applications and Experiments for the Sun-Earth-Moon Model
The tellurion turns abstract astronomy into motion a class can follow: turning the gear train shows why the Sun appears to rise and set, why the seasons change through the year, and how the Moon's position produces its phases and eclipses. It suits school science, geography and introductory astronomy lessons.
- Middle-school science and geography (CBSE/NCERT Class 6–8): rotation, revolution, day and night and the seasons.
- Class 9–10 science and geography: the lunar cycle and the geometry of eclipses.
- B.Ed. and teacher-training courses: using working models as astronomy teaching aids.
- Science clubs: explaining Earth–Moon–Sun positions before a sky-watching session.
Standard Scope of Supply
The Sun-Earth-Moon Model is supplied as a single geared unit as described above; any optional accessories are listed on the quotation. The quotation also confirms the construction and dimensions of the model offered, so you can match it against your syllabus list or tender specification.
Packing, MOQ and Lead Time
Ask for one model for a single classroom or several for every section of a school; the quotation gives the packing, delivery time and price for the number you need. Other teaching aids from our physics lab equipment in India range can be quoted alongside it for one delivery.

Frequently Asked Questions
What does the Sun-Earth-Moon Model demonstrate?
It shows the seasons, the alternation of day and night, the cycle of Moon phases and the positions that cause solar and lunar eclipses, using gears that reproduce the movements of the Earth and Moon.
Is this the same as a tellurion?
Yes. A geared model showing the Sun, Earth and Moon together is commonly called a tellurion or tellurium, so a syllabus or tender using either name refers to this type of model.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies makes this model itself. Production takes place at the company's own factory in Saha, Ambala, India, and every quotation is issued by the factory rather than by a reseller.
Which classes can use the model?
It fits middle-school lessons on rotation, revolution and seasons and secondary lessons on Moon phases and eclipses, and it also serves teacher-training sessions on basic astronomy.
