I know this isn't math but no body would help me in the science section.

Night time will always be on the side of Earth facing away from the Sun. Since we orbit in a circle (ellipse), night time on Earth will always be facing outwards towards the stars rather than inward toward the Sun. This is why as we make a full 360 degree orbit over the course of 1 year our view of the stars in the night sky changes.

Ok, thank you then why can we always see Ursa Minor, (aka little dipper).

It is all to do with the latitude that you live on.
