What causes sunrise and sunset each day?

Every day the sun appears to rise in the east and set in the west. Morning gets light. Evening gets dark. That daily pattern is something you can watch and count on.

Why does the moon seem to change shape?

The moon looks a little different on different nights.. Draw the moon tonight. Draw it again in a week. The shape will change.

Is this true? It is not true that People group bright stars into pictures to remember them.

No. People group bright stars into pictures to remember them. The Big Dipper looks like a cup with a long handle. You can look for the same star pictures on clear nights.

Why are summer days longer than winter days?

Summer days have more daylight. Winter days have less. You can feel it: in summer you play outside later. In winter it gets dark sooner.

How do shadows change during the day?

As the sun moves across the sky, shadow length and direction change.. A stick's shadow is long in the morning, short at midday, long again later.

Is this true? The sky has patterns you can watch: the sun comes up and goes down each day, the moon's shape changes over many nights, and summer days last longer than winter days.

Yes. Sun each day, moon over many nights, longer days in summer. Those are sky patterns.

Match each prompt to its fact.
