About This Product
Students look from the Earth position as the Moon is moved round its orbit, watching the lit part grow through crescent, first quarter and gibbous to full. Reading the degree markings at each stage records the angle between the three bodies. Lining the Earth up between the Sun and Moon shows a lunar eclipse, and older students can link the phases to spring and neap tides.
Frequently Asked Questions
Is the Moon orbit motorised on this model?
No. The orbit mechanism is moved by hand; only the LED Sun needs power.
How many Moon phases does the model show?
It tracks the 8 primary phases, from New Moon to Full Moon and back.
