Light up the Sun with this version of Orbiter. This model can be plugged into a standard wall outlet (UL approved - 6" power cord) to illuminate the Sun to effectively demonstrate daylight, night, seasons, and phases of the Moon. The Sun, Earth and Moon manually revolve around one another on this gear-driven model. The earth and moon are shown in true scale. The scale is 1 inch = 2000 miles. If the sun were to be shown at the same scale, it would be approximately 36 feet in diameter. Arm is 15", Sun is 6" and the Earth is 4" in diameter. This 8 page Lesson Plan includes basic investigations and activities on Day and Night, The Seasons, The Moon, and Oberservations and Activities. For grades 3 to 12 and ages 8 to 18 years.
