The appearance of the lighted portion of the moon changes on a predictable cycle as a result of the relative position of Earth, moon and sun.
Earth orbits the sun and rotates on a tilted axis to create seasonal changes.
Identify the pattern of change of the moon s appearance. Describe changes in the appearance of the moon during a month. Use observable evidence to explain the movement of the moon around Earth in relationship to Earth turning on its axis and the position of the moon changing in the sky. Design an investigation, construct a chart and collect data depicting the phases of the moon. Identify the difference between the motion of an object rotating on its axis and an object revolving in orbit.
