Compare and draw the day sky and night sky, noting which objects are visible in each.
The sky looks very different during the day compared to at night. During the day, you can see the Sun and sometimes clouds, but the sky is too bright to see stars, even though they are still there. At night, the sky turns dark, and you can see the Moon and stars instead.
Comparing the day sky and night sky is a great way to notice a pattern: certain things are only visible at certain times.
Mastery looks like: They produce a day-sky and night-sky drawing or description and correctly explain that stars are present but not visible during the day.
Common stumbles: Believing stars only exist at night; leaving out the Moon, which is sometimes visible during the day too.
