Eisco Sun, Earth, & Moon Orbiter Model

Eisco Sun, Earth, & Moon Orbiter Model Grades: 5-12 Number of Students: 2-4 Number of Lessons: 4+ Contact Hours: 2-4 Additional Resources: Experiment Guide   Highlights: 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 model features a 5.9" Sun, a 4" diameter Earth and a 1" diameter Moon.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. The Sun has LED inside which demonstrates the effect that sunlight has on the Earth and Moon. Requires two AA batteries (not included).The sturdy bas
