The Sun, Earth and Moon orbiter helps demonstrate daylight, night, seasons and phases of the moon orbit.  The Sun, Earth and Moon revolve around one another on this gear driven model. 

The model is equipped with an LED which is located inside the sun to show the effect that sunlight has on the Moon and the Earth (2 x AA batteries required - not included).

The sturdy base is labelled with the months of the year allowing learners to explore the relative positions of the Earth both monthly and seasonally.

• Overall Dimensions: (H)310mm x  (W)413mm x (L)121mm
• Diameter of the Sun: 150mm
• Diameter of Earth: 102mm
• Diameter of the Moon: 26mm
• Batteries not included (2 x AA required).

This three dimensional model allows students to study the motion of the Earth and Moon around the sun, and demonstrates the science behind phenomena such as seasons, phases of the moon, eclipses, and tides. During Earth's one-year period of revolution, the tilt of its axis results in changes in the angle of incidence of the Sun's rays at a given latitude. These changes cause variation in the heating of the surface which produces seasonal variation in weather.

The Earth can be manually moved to show its rotation around the Sun, and the Moon can be moved to show its rotation around the Earth. 

Model includes a comprehensive experiment guide that includes three activities, worksheets and various topics for further exploration, as well as Solstice and Equinox charts.
