The Physical Setting: The Earth
Grades 3-5, page 68

Like all planets and stars, the earth is approximately spherical in shape. The rotation of the earth on its axis every 24 hours produces the night-and-day cycle. To people on earth, this turning of the planet makes it seem as though the sun, moon, planets, and stars are orbiting the earth once a day.
 

NSES Content Standard D  Earth and Space Science: Changes in the Earth and sky  Grades K-4, page 134  Objects in the sky have patterns of movement. The sun, for example, appears to move across the sky in the same way every day, but its path changes slowly over the seasons. The moon moves across the sky on a daily basis much like the sun. The observable shape of the moon changes from day to day in a cycle that lasts about a month.  NSES Content Standard D  Earth and Space Science: Earth in the Solar System   Grades 5-8, page 160  Most objects in the solar system are in regular and predictable motion. Those motions explain such phenomena as the day, the year, phases of the moon, and eclipses.
