HOW DAY AND NIGHT IS CAUSED????

Have you ever wondered how day and night is caused? 
It is because the earth rotates. Well, let's do an experiment to prove it!

Materials:
Globe
Torch


Instructions
This experiment can only be done at night.
Switch all the lights off, close the curtains and shut the door in the room you are performing this experiment.
Now on the torch and point it on the globe. The side facing to the torch gets the light. Now keep rotating the globe.

Observe: The side facing the torch always gets the light. The opposite side does not gets any light. The torch is like the sun. The sun is giving the light, but only the side facing the sun gets the light.
So, the earth do not have day or night at all the sides at the same time!

THE RIGHT SIDE HAS NIGHT AND THE LEFT SIDE HAS DAY IN THIS IMAGE
