(6-8) Earth’s spin axis is fixed in direction over the short-term but tilted relative to its orbit around the sun.These include day and night daily changes in the length and direction of shadows and different positions of the sun, moon, and stars at different times of the day, month, and year. (5) The orbits of Earth around the sun and of the moon around the Earth, together with the rotation of Earth about an axis between its North and South poles, cause observable patterns.(6-8) Patterns of the apparent motion of the sun, the moon, and stars in the sky can be observed, described, predicted, and explained with models.Next Generation Science Standards Disciplinary Core Ideas for 3-Video Series ![]()
