It takes the moon 28 days to revolve around the Earth.
Why do we see different sized shadows throughout the year even though we check the shadow length at the same time each day?
This is because the sun takes a different path throughout the year depending on the tilt of the Earth as it revolves around the sun. In winter, it takes a lower path and in the summer it takes a high path.

Does the moon change shape? Explain your thinking.
No, the moon does not change shape. It only looks like it does because the sun is only able to shine on portions of it throughout the month. This is because the Earth blocks parts of the moon from the sun.
