The best time of year to view the Big and Little Dippers in the evening sky is late Spring. This is the time of year that they are both at their highest in the sky. To find the Big Dipper, go outdoors as the sky grows dark. The Big Dipper will be almost overhead on the northern side of the sky.
Once you find the Big Dipper, you can use it to find the Little Dipper. The Little Dipper is fainter than the Big Dipper, so to find it may require you to get away from the light pollution of the city. The brightest star in the Little Dipper is the north star. The north star is at the end of the handle of the Little Dipper. While the north star is the brightest star in the Little Dipper, it is not a very bright star.
From the north star, you can follow the handle up toward the Big Dipper. The top (at least in this position) and brightest of star of the Little Dipper’s bowl is Kochab, a yellow star. Kochab is neat because it is one of the few yellow sun-like stars we can see in the sky with our eyes.
Below is a chart to help you locate them.
