Light and Dark 

• Our surrounding is bright due to the light.

• Without light, our surrounding will turn dark and make it hard to see. 

• Activities during light and dark. 

• The main source of light for the earth is the sun. Sun emitted light and lit up the earth surfaces. 

• During night time, human uses other sources of light to lighten up our dark environment to see better. 

• Shadow is formed when light is blocked by an object. 

• When the lights are blocked, this will cause a formation of a dark image similar to the shape of the object that blocked the lights. 

• The clarity of a shadow depends on the opacity of the object that blocks the light. 

• A transparent object cannot form a shadow. 

• The size of a shadow depends on the distance between the light source and the object. 

• The nearer the object to the source of light, the bigger the size of the shadow. 

• You can try observing the shape of the shadow by creating shapes by using your hands.
