About This Product
Starting with all arms on one line, students move the planets to compare the short paths of the inner planets with the long orbits of the gas giants, and to set up conjunctions. With the room dimmed, the LED Sun casts shadows that introduce day and night, and the degree scale lets them record angular displacement over a simulated time. Educational Instrument can arrange export supply of the Solar System Manual Model STEM Lab to United States, Benin, Uganda, Turkmenistan and Uzbekistan.
Frequently Asked Questions
Are the planets in the Solar System Manual Model to true scale?
No. A modified scale is used so that all planets fit and stay visible, while relative order of size is kept, with Jupiter the largest.
Is the model motorised?
No. It is a manual model; students move each planetary arm by hand.
