LIGHT

This term we are learning about Light and Colour. This week we carried out these experiments and this is what we found.

We looked to see what happened when we put a straw in a glass of water. 
The straw looked bent but it wasn't. The light was bending.

When we look at a straw in a glass of water, light from the top of the straw travels straight to the eye.
Light from the part that is under the water is refracted when it goes from the water into the air. It changes direction. 
That is why the straw looks bent.

In groups of three, one held a torch and shone it on a mirror which someone else was holding.Our third person was holding a piece of white paper which was our screen. 
We found that the light travelled in a straight line to the  mirror and then reflected off the mirror onto the screen.
