Light up the Sun with this electronic illuminated orbiter. This model can be plugged into a standard wall outlet 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 the 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! The arm is 15", the sun is 6" in diameter, and the Earth is 4" in diameter. The 8-page lesson plan includes basic investigations and activities on day and night, seasons, the Moon, and other observations and activities. Highly recommended for use in the science classroom!
