Use observations of the Sun, moon, and stars to describe patterns that can be predicted.
Clarification statement: Examples of patterns could include that the Sun and moon appear to rise along the eastern horizon, move in a predictable pathway across the sky, and set along the western horizon; and stars other than our Sun are visible at night depending on weather and other conditions such as light pollution but not visible during the day.
Assessment boundary: Assessment of star patterns is limited to stars being seen at night and not during the day.
