A Shadow is created when a light source is being blocked by an object and the shadow becomes bigger when the light source comes closer to the object.

The sun is the biggest source of light in the world it even reflects light on the moon,the light travels in straight lines.

Darkness happens when there is no light, when the sun sets we get night which is dark as sun takes away light and we have to use other sources to get light.

Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground.

Sources of light

Light travels from a light source.

Natural light

Sun is the main source of natural light. Other forms of natural light are other stars and moon. Star provides very less amount of light at night because they are very far from earth compared to sun. Moon, especially full moon provides little light at night but light from the moon is just light reflected from the sun. Some animal also emit their own lights such as glow-worms, fireflies and some fish.
Artificial light

Source of artificial light are burning wood, candles, earthen lamps. Candle are made of wax, oil and wick are used in lamp to burn. Now days we use electric bulb, tube and lamp as source of light.

Examples of different light sources are - Sun is a natural source of light, Electricity and Candle. A Shadow is formed when any light source is behind an Object.
Dark is when there is no light source. There are no shadows when it is dark.

A shadow is formed when the sun is facing an object. The sun can't go through the object so it forms a shadow.But if the clouds blocks the sun there will be no shadow at all.
The sun is a very strong source of light. It even reflects its light on the moon.

Did you know that if there was no sun the universe would be a big black blob.
The sun has gravity so if you went near it wouid suck you up into fire.

At night everyone is supposed to be asleep but not all animals are.
It is good to sleep in the night because if you sleep night the dark helps you to sleep.
