Applications and Experiments for the Orbit Tellurium 2
With the lamp lit, the model shows why one side of the Earth has day while the other has night, how the tilted axis produces seasons and changing day length, and how the Moon’s position creates phases and eclipses. The sundial and model person let pupils watch shadows change during a day and a season.
- Primary science and geography: day and night and the Sun’s apparent motion.
- NCERT Class 6 geography: motions of the Earth and seasons.
- Middle-school science: phases of the Moon and solar and lunar eclipses.
- Shadow studies with the sundial, lined up using a Pocket Compass.
- Modelling sunlight on a globe with the straight beam of a Parallel Beam Light Source.
Standard Scope of Supply
The set includes the tellurium model, a model sundial, an Earth axis extension, a stick-on model person, a phase of the Moon indicator, an eclipse shadow card, a date indicator, two Earths and Moons, the teaching guide and the 6 V transformer for electrical operation.
Packing, MOQ and Lead Time
One tellurium can serve a whole class or a geography room, and more can be ordered for several rooms; each quotation states the packing, delivery time and price for that quantity. An orrery or other astronomy models can share the same quotation.
Holding an Importer-Exporter Code, Science Lab Supplies is a registered exporter that can ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman. Write in about the tellurium on the contact page, add it to a list of teaching models in the enquiry cart, or include it in a tender through the lab tender page.

The tellurium focuses on the Earth, Moon and Sun; the models below widen or support the topic. An orrery shows the full solar system, a second geared model covers the same system, and day-and-night, seasons, Moon-phase, eclipse and time models break each lesson down further, all on one quotation.
- Orbit Orrery — 380 mm outermost orbit and a sun lit by two AA batteries.
- Sun-Earth-Moon Model — for seasons, day-night alternation, moon cycles and eclipses.
- Model of Day and Night — shows how Earth’s rotation produces day and night.
- Four Seasons Appratus — relates axial tilt and orbital position to the seasons.
- Model of phases of Moon — shows the changing illuminated portion of the Moon as it orbits Earth.
