Astronomy teaching model of the Sun, Earth and Moon system. This attractive hands-on astronomy tellurium model shows the Sun, Earth and Moon, correctly geared to show each month as the Earth orbits the Sun. A high quality tellurium designed to demonstrate on a large scale the relative movements of the Sun, Earth and Moon, so that the causes of a number of phenomena can be understood such as day and night, changing length and direction of shadows, seasons of the year, phases of the Moon, eclipses of the Sun and Moon. Teacher's notes written for the non-specialist astronomer cover all these topics. The flexible design instantly engages pupils and illustrates complex relationships more easily. Rotate the model and watch as the Earth orbits the Sun, the moon orbits the Earth and the Earth spins on its axis. Shine the light from the sun onto the Earth to model night and day, the seasons and eclipses and create shadows. Use the small-scale Earth and Moon on an inclined orbit to give an accurate demonstration of the phases of the moon and show why eclipses do not happen every month. Subjects to study:. Day and night. Seasons of the year. The sun's movement across the sky. Changing length of daylight. Shadows. The phases of the Moon. The crescent moon from different latitudes. Eclipses of the Moon and Sun. Use of sundials and shadow sticks. Lunar months and festivals linked to the Moon.
