Product Code : SCL-ALE-11954
Model of Day and Night (SKU SCL-ALE-11954) is an astronomy teaching aid for demonstrating how Earth's rotation produces the repeating cycle of daytime and nighttime. It shows why places facing the Sun have daylight while places facing away are in darkness, and suits astronomy, geography, Earth science and general science lessons in schools. Science Lab Supplies manufactures the model in Saha, Ambala, India, at Plot 448 of the HSIIDC Industrial Area, and prices it directly for schools, distributors and tender contractors.

Applications and Experiments for the Day and Night Model
With the model, a class can pick one place on Earth and follow it through a simulated day as Earth turns, from sunlit side to dark side and back. Students then explain that Earth's rotation, not the Sun moving around Earth each day, produces the cycle they observed.
- Primary and middle-school science: Earth's rotation and why day and night occur.
- Geography: why different places have daylight at different times.
- Night-sky follow-up: the stars visible from the dark side, introduced with the Globe of Celestial.
- Earth science units that also cover the planet's interior, using the Earth Layer Structure model.
If the unit you receive includes a lamp or powered mechanism, run it only at its rated supply and as its instructions describe; never force moving parts.
Standard Scope of Supply
A single Model of Day and Night from the Ambala factory forms the standard supply. The quotation states whether it carries a lamp or Sun representation, how it rotates, and its material, scale and size, so a teacher knows how the demonstration will run before the order is confirmed.
Packing, MOQ and Lead Time
A price can be given for one day-and-night model or for several for a whole primary section. The quotation names the packing, delivery time and price for that quantity, and the time-indicator, seasons and Sun models or STEM science kits can be added to it.
As holder of an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Oman, the Philippines, Nepal, Bangladesh, Zambia and Rwanda. Ask for a day-and-night model price on the contact page, place it in the enquiry cart, or start a tender through the lab tender page.
Frequently Asked Questions
How are day and night formed?
At any moment, the half of Earth facing the Sun has daylight and the half facing away has darkness. As Earth rotates, most places pass through both conditions in roughly 24 hours, which the model lets students follow step by step.
Does the model include a built-in light source?
Whether a lamp, Sun representation or electrical supply is part of the unit is set out on the quotation. Where a lamp is fitted, check its moving and electrical parts before each class.
Is the model made to astronomical scale?
No. It is a demonstration model, not a precision scale replica. Dust it with a soft, dry cloth, store it in a dry place away from impacts and moisture, and never force a rotating or detachable part.
Is Science Lab Supplies the manufacturer or a trader?
Day-and-night models from Science Lab Supplies are produced in the company's own Saha, Ambala factory. Being the manufacturer, it issues the quotation and arranges packing and dispatch itself rather than buying in from another supplier.
