  • Did you know that a lot of animals can see at night?

They have special eyes that help them see even in the dark. If there is zero light, however; even animals with the best night vision would not be able to see.  

Humans need more light than most animals in order to see.

We need a few other things to see as well like our eyes and our brain. Let's find out how these things work together to help us see!

Without light, you wouldn’t be able to see. It is a good thing we have the sun. Can you think of a few other sources of light? If you thought about electricity or lamps, great job! Also, if you thought of a camp fire, you got it! There are a lot of different sources for light, and they are all helpful when it comes to seeing.

Watch this Scholastic Study Jams video all about Light and take the quiz at the end. Have fun!  

In addition to light, you also need your eyes and brain to see. 

  1. Light reflects off of objects and into your eye where it is projected.
  2. The image projected is transferred into electrical impulses that travel down the optic nerve to the brain.
  3. The brain interprets the impulses and tells you what you are seeing!
