Function and applications
Device for demonstrating the movements of the earth and moon. Models of these celestial bodies rotate on a lever arm around a light source that represents the sun. A Fresnel lens is used to generate an extremely bright, parallel light beam for full irradiation of the terrestrial globe. The focussing of a point of light on the globe serves to represent the apparent migration of the sun between the tropics.

Benefits
By using the Fresnel lens, day and night, seasons, moon phases and eclipses are clearly demonstrated. Equipment and technical data
Detailed instructions are included for the following 13 teaching units:
Earth as a top - day and night - hour - polar day and polar night - tropics - seasons - day and night lengths in different latitudes - times of day - moon phases - eclipses - tides - earth circumference - geostationary satellite.
