Laser Water

Here is an experiment we did in class about lights and water.

It is just a trick, but how does it work...?!

Shadows

Today we started our light topic. We watched this video, then got to make our own shadow puppets.

We were asked a few questions:

1. How do you make the puppets bigger/smaller?
2. How does this work?
3. What do shadows tell us about light rays?
4. How do we use shadows in everyday life? OR How do we stop shadows causing problems in everyday life?
