To locate the pole star (Polaris) with the help of Ursa Major, also known as the Big Dipper, you can follow a simple step-by-step process:

1. Find Ursa Major: Look for the Big Dipper constellation in the night sky. It is one of the most recognizable and easily identifiable star patterns.

2. Identify the two outermost stars of the Big Dipper's bowl: These stars are called Dubhe and Merak. They are usually referred to as the "pointer stars."

3. Imagine a line between the two pointer stars: Extend an imaginary line from Dubhe to Merak, and continue it for about five times the distance between these two stars.

4. Locate Polaris: The imaginary line extended from the pointer stars will lead you to Polaris, the pole star. Polaris is relatively bright and has a steady position in the northern sky.

Keep in mind that this method works best in the Northern Hemisphere, where Polaris is positioned close to the north celestial pole. In the Southern Hemisphere, the pole star is not easily observable, and different methods for navigation may be used.
