Long ago, people did not understand light. Some thought it was a kind of air.

Just over 300 years ago, Isaac Newton wrote a book about light. He asked questions such as 'What is light?'. We still use some of his ideas today, but now we understand much more about light.

Isaac Newton and other people did experiments to find out about light.

Find more information about Isaac Newton. Look in science books and on the internet. Make notes and share these with your friends.

Now write about light or make a poster about light.

You can write about:

- Isaac Newton (don't forget that his ideas were new at the time)
- light sources
- things that are not light sources
- darkness
