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).
