If you were to observe the Moon over a 4-5 night period, where you observe the Moon at the same time each night: what would you notice in terms of changes related to the size, shape (i.e. phase) and location of the Moon.

You will be able to see
1. size varies only slightly (almost unnoticable). It varies because moon has elliptical orbit
2. phase changes like a sine wave. From full to dark to full and again full
3. The moon shifts its location along a straight line every day a little. Because angular speed of earth and moon is different.
