LAC 28:XI.9740. Earth’s Place in the Universe

A. Use an Earth-sun-moon model to show that the Earth-moon system orbits the sun once an Earth year and the orbit of the moon around Earth corresponds to a month. B. Use an Earth-sun-moon model to explain eclipses of the sun and the moon. C. Use an Earth-sun-moon model to explain how variations in the amount of the sun’s energy hitting Earth’s surface results in seasons. D. Use a model to identify the solar system as one of many systems orbiting the center of the larger system of the Milky Way galaxy, which is one of many galaxy systems in the universe. E. Use a model to describe the relationships and interactions between components of the solar system as a collection of many varied objects held together by gravity. F. Use data (e.g., statistical information, drawings and photographs, and models) to determine similarities and differences among solar system objects.
