My experiment today was to get a pencil, water and A clear glass or jar.
I had to fill the glass half way with water then I placed the pencil in the glass. When I looked at the pencil at the top of the glass the pencil appeared bent as seen on photo 1.

Then when I looked at the pencil from the side of the glass it had a different effect. I could see two pencil's as you also can see on photo 2.
What happens when you look at a pencil through the side of the glass? Light play's tricks on your eyes. The pencil looks bent. This is because light travels slower through water than through air. As the light enters the glass of water it slows down (changes direction) and as it leaves the glass it speeds up again- therefore making the pencil look as though it is bent! Pretty cool eh!!

My science expriment about
How to make rain.

Today I made rain and these are the steps on how to do it.


step.1 Get a flat plate

step.2 Get some gloves

step.3 Boil the jug

step.While the jug is boiling put the plate above the jug and when the jug stops boiling you will see that little drops of water is there.



The way that rain works is when its a really hot day the heat goes up to the clouds in the sky. When this happens it creates moisture in the clouds.Which becomes rain.
