Light and Dark
 
Objective
 
Students will be able to know about:-
 
• Light and it’s use
• Sources of light
• Properties of light
• The meaning of reflection and shadows
Light is an energy weight from the sun, lump, etc. We need light to see things. You can see because your eyes take in light from whatever you are looking at. When there is not any light, things are dark. You cannot see anything when there is no light.
 
For example: - If you want to read a newspaper in a room. the room must be filled by a light but if there is no light in the room you cannot read the newspaper.
o Bright lights can harm your Eyes
o Direct light from the sun is very strong and can damage your eyes.
 
Some Sources of light
 
o The sun
o A candle flame
o The stars
o An Electric light
 
Some objects like the moon, the planets, mirrors are not sources of light.
 
Two Properties of light
o Light travels in straight lines from a light source.
o If something opaque than you will get a shadow.
o Opaque: material do not low light to pass through them.
 
How we see things?
 
We see things when light enters our eyes. The way the light enters our eyes may be different.
• It may enter our eyes directly from a light source or
• It may enter our eyes after it reflects of objects.
 
Light bounce of some materials better than others
1. Mirrors and shiny objects reflect almost all of the light that falls on them.
2. Dull, dark and objects absorb most of the light falls on them.
 
Mirror and reflections
 
Reflection is the bouncing back of light rays. Mirrors reflect light back at the same angle. When light hits a mirror it bounces back off it again and you get a reflection. A light ray hitting a mirror is reflected back at the same angle. That means that you can use mirrors to see around corners or behind you.
 
Shadows
 
Shadow is a dark area made when light rays are blocked by an object.
When light from a source is blocked you get a shadow.
