Sources of Light

Short video introducing and explaining sources of light.

Go outside and look around you. What things can you see?

You can see the things around you because of light. Light is a form of energy.

During the day, the light from the sun helps you to see.

Note: The light from the sun is very helpful, but it can also be harmful. It can damage your eyes and skin.

Never look directly at the sun and wear sunscreen on sunny days.

At night, there is no light from the sun. People use light bulbs, flashlights, headlights and fire to see the things around them.

What things do people use to help them see at night?

The sun, lamps and fire are things that give off light of their own. Something that gives off light of its own is called a source of light.

Some sources of light are found in nature. They are not made by people. They are called natural sources of light. The sun, stars, fire and lightning are natural sources of light.

Many sources of light are made by people. They are called artificial sources of light.

Electrical lights are artificial sources of light. They light up our cities, streets and homes at night. Televisions, computer monitors and phone screens give out light. They are also artificial sources of light.
