"The Plough", "Butcher's Cleaver", "Charlie's Waggon" or "Great Bear (Ursa Major)"
1. It's not a constellation. 2. It's an asterism, which happens to be PART of a constellation, the Great Bear. 3. Asterisms can also be BIGGER than constellations and include several of them, as the "Summer Triangle" includes the Lyre, the Swan and the Eagle. 4. It's used to find the North Star, but this won't always be the case. 4a. For one thing, the Earth's slow wobble (called "precession") means in a few thousand years, Polaris won't be the North Star any more; 4b. For another, the proper motion of the stars of the Dipper means that the "pointer" stars won't always be pointing to Polaris. 5. Many cultures recognize the Big Dipper, but they call it different things: sometimes it's a drinking gourd (Africa); a bear (!) pursued by three Indians (America) or a wagon (Europe) or a plough (also Europe).
From the viewpoint of the Earth, all the constellations 'revolve' around Polaris (the North star. As the Earth orbits the sun, its relative position to the constellations changes - and they appear to move across the night-sky.

Yes, there are four stars that form the bowl of the Big Dipper constellation. These stars are Alkaid, Mizar, Alioth, and Megrez.
The big dipper is shaped like a pan, which in the past was called a dipper. Dippers were used to scoop up water. It gets the big part from being bigger than the little dipper, another constellation.
Seven stars make up the Big Dipper - from bowl to handle: 1)Dubhe 2) Merak 3)Phecda 4)Megrez 5)Alioth 6) Mizar (and Alcor) 7) Alkaid
The Big Dipper is located in the northern sky, visible year-round for observers in the Northern Hemisphere. It is part of the Ursa Major constellation and can be used to locate the North Star (Polaris) by following the line formed by the two outer stars at the end of the Big Dipper's bowl.

Viewed from anywhere in the USA, the Big Dipper makes a complete revolutionaround the North Star ... like the hands of a clock ... every day.On the scale of a year, it reaches any certain position about 4 minutes earlierevery night, so that in the course of a year, it reaches that position 24 hoursearlier than it did 365 nights before.
