Four Seasons Appratus
Product Code : SCL-ALE-11959
Four Seasons Appratus (SKU SCL-ALE-11959), correctly spelt Four Seasons Apparatus, is an astronomy teaching aid that demonstrates how the axial tilt of the Earth and its position in orbit around the Sun produce spring, summer, autumn and winter. It suits astronomy, geography and Earth science lessons in schools and colleges. Built by Science Lab Supplies in its Saha, Ambala factory in India, it is quoted directly to schools, colleges, distributors and contractors.
Specifications
The seasons demonstrator is documented in the table below. In short, it is one Earth–Sun apparatus for showing why each hemisphere receives sunlight at a changing angle and for a changing length of time through the year; its material, size, light source and mechanism are confirmed on the quotation.

Applications and Experiments for the Four Seasons Apparatus
Moving the Earth to different points of its orbit, students see that the axis keeps its tilt and orientation while the hemisphere leaning towards the Sun changes. Comparing opposite positions explains why the Northern and Southern Hemispheres have opposite seasons, and why sunlight angle, not distance, drives the change.
- Middle-school science and geography: causes of the seasons and the yearly orbit of the Earth.
- Earth science: sunlight angle and day length in each hemisphere through the year.
- Senior astronomy: relating seasonal positions to the celestial sphere on the Globe of Celestial.
- Solar-system lessons that start from planetary order on the Working Solar System Model Big.
Do not force movable parts; if a lamp is fitted, use only its stated supply and let it cool before handling.
Standard Scope of Supply
A single Four Seasons Apparatus is supplied. The quotation details its construction material, dimensions, the size of the Earth model, the Sun representation or light source and how the orbit is moved, so you can confirm it matches the seasons lesson you plan to teach before placing the order.
Packing, MOQ and Lead Time
Quotations can be prepared for one seasons apparatus or for a batch serving several classrooms. Packing, delivery time and price are written out for the exact number, and day-and-night, eclipse or Moon-phase models from the same science kit manufacturer in India can be included.
Science Lab Supplies holds an Importer-Exporter Code and can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Requests for this apparatus can be sent from the contact page, collected in the enquiry cart with other models, or handled as a bid via the lab tender page.
Frequently Asked Questions
What causes the four seasons on Earth?
The seasons arise mainly from the tilt of the rotational axis of the Earth as it orbits the Sun. This changes the angle and duration of sunlight that each hemisphere receives during the year.
Does the apparatus include a lamp?
The Sun representation, any light source and its electrical rating depend on the version supplied and are confirmed on the quotation. If a lamp is included, operate it only on the stated supply and allow hot parts to cool.
Can it show opposite seasons in the two hemispheres?
Yes. Setting the Earth at roughly opposite points of its orbit shows one hemisphere tilted towards the Sun and the other away from it, which is why summer in one coincides with winter in the other.
Is Science Lab Supplies the manufacturer or a trader?
The seasons apparatus is assembled by Science Lab Supplies itself at its Saha, Ambala, India premises. Buying from the maker means one point of contact for price, packing and the dispatch schedule.
