Sources of Light | Science for Kids | Kids Academy

Science for kids is fun and very interesting. They love learning about things that they see around themselves. For some kids’ science is cool, others find it intriguing, some just find it fun, in either way kids show good interest in science.

One of the very interesting topics in science is light. It is a part of the early curriculum and teaches some of the basics. When you start teaching your kid about the light you need to go to the very basics too. The kid needs to understand what actually light is and where does it come from.

Sources of light is a very early lesson that kids need when they start understanding the concept of light. To help you explain this to your kid in easy words let me explain it to you in simple words.
What is light?

Light is what enables you to see around you. To put it in the words of science, light is made up of waves. And where do these waves come from? These waves travel from light sources, the bounce of different objects and enter our eyes, which then allows us to see things.
The kids can later understand the concept of waves in their higher grades.

What are light sources?
Now that the kids know that light waves come from light sources. Now they would surely ask you about the light sources.

Light sources come in all sizes and shapes. Small lights can help light up streets or small rooms, big lights can help light up big stadiums. Sources of light are all around us, very rarely you will find yourself in complete darkness with no source of light.

The main source of light to the world is the sun. it is the biggest source of light to the earth. Now, apart from the sun, there are other light sources to help you when the sun is not there. We have electric lights like in your house, on your phones and tablets.
Another, not to forget, the light source is the moon.

The moon reflects the sunlight on us. So, when nothing else is there to light up at night, the moon is there for you. And even if the moon refuses to show up, you always have stars. Stars are also a major source of light and keep earth lit at night time.
When there is no source of light, this is when it would be completely dark and you will not be able to see anything.
