Science Lesson - what is light

We are looking at alot of science concepts. Todays was about light. I have to write notes and write a blog on what I remember.

Light travels from a source.

 The sun is the source of light in our solar system. 

We can also create our own source of light. We need light to see at night time.

Light reflects off objects that can't pass light through.

The light goes into our eyes. Our eyes change light into electrical impulses. Messages of what we see are then sent to the brain. That's why we can see things.

Shadows are made  when light can't pass through an object. It leaves an exact shape of the object.
