This activity should be performed on a clear moonless night during summer at about 9.00 p.m. Look towards the northern part of the sky and identify Ursa Major. You may get help from elders in your family. Look at the two stars at the end of Ursa Major. Imagine a straight line passing through these stars as shown in Fig. Extend this imaginary line towards the north direction. (About five times the distance between the two stars.)

This line will lead to a star which is not too bright. This is the Pole star. Observe the Pole star for some time. Note that it does not move at all as other stars drift from east to west.
