YOU NEED:
Inflate a beach ball and stick a small paper shape onto It. Place the ball on a table. Darken the room and shine a beam of torch light (Sun) towards the ball .One half of the ball is lit up while the other remains in the shadow. Spin the ball to see how the shape passes from night to day as the earth goes around.
HOW DOES IT WORK?
The light from the torch comes in contact with the half of the ball which is directly in the front and the light rays (travelling in a straight line) are unable to reach the other half of the ball which is thus left as a shadowed area. This is explains why we have day and night.
