Role Play: Stationary Position of the Pole Star
\r\n
\r\n\r\nProcedure:
\r\n\r\n\r\n\t- Stand and hold one hand straight up and point towards a fixed overhead point (for example, a light bulb or a ceiling fan).
\r\n\t- Imagine that you are the Earth and rotate in an anticlockwise direction. Keep looking at the overhead point while you are rotating.
\r\n\t- Stop after you complete a couple of rotations. Did the point / object, which was exactly overhead, appear to move?
\r\n\t- The star right above the North Pole does not appear to move, which is why it is called the Pole Star!
\r\n

Draw a diagram explain why position of the polestar does not appear to change.
\r\n \r\nUse your notebook for drawing. Please write following on page where you are drawing- The Basic Astronomy Module: Unit 1: Lesson 2: Activity 4 & your Login ID

\r\nDo you know the story of Prince Dhruva? If not, find out from elders in your family or friends. Are you aware of any other stories which are related to astronomy?
