How was the Big dipper created?
The Big Dipper, also known as the Plough or the Great Bear, is a prominent asterism in the constellation Ursa Major. It was formed by a chance alignment of its seven brightest stars as seen from Earth. These stars vary in distance from us and are not physically related to each other, but from our viewpoint, they appear to form the shape of a ladle or dipper in the sky.
What length of time is required for the Big Dipper to change from one position to the other?
From the point of view of an observer on earth, the stars are always moving.
The question is: How long does it take you to notice a change in position ?
If you line up a star with a tree or a house, you ought to be able to notice it
within 5 minutes.

Where is the big dipper located?
The Big Dipper or 'Plough' or 'Saucepan', is a collection of stars that form part of the constellation Ursa Major (The Large Bear). A constellation is a group of stars that appear to form a pattern in the sky. In reality these stars are in some cases millions of light-years distant from one another, and do not form an actual physical body in space.
The Big Dipper is easy to spot most of the time in the north hemisphere as it contains one of the brightest stars in the night sky, Polaris or 'The North Star'.
What are 4 other names for the big dipper?

approximate time. More on http://oliodigest.com/science/astronomy/tell-time-by-the-big-dipper-constellation.html
How can you see the big dipper upside down?

It is moving South. At sea you could measure the angle between the horizon and Polaris with a sextant. This angle is approximately equal to your Northern latitude. There are some mathematical corrections one can perform to get a more precise answer, but the further south you sail, the lower Polaris will become. Eventually, you will not be able to see it anymore. Polaris is not visible from the Southern Hemisphere and there is no South Star. The ship is in the Northern Hemisphere, moving South.

In the northern hemisphere, the north star never moves in the night sky, no matter what time of night, all the other stars move from east to west over the course of the evening. The north star is due north of the north pole.
The number of degrees the north star is above the horizon will always indicate the lattitude of the observer. For instance, Boston is at around 42 deg N lattitude, the north star is around 42 deg above the horizon when looking north.
