Year 4 is investigating light this term. We will discover what makes this all important form of energy unique, what it's properties are and also how many different types of light there are in our universe. We will have lots of opportunities to investigate how light travels, how mirrors and lenses change how light behaves, and how light helps us to see.

Optical Illusions
|
Do you see what I see? Optical illusions are designed to make us questions what we see. They trick us into perceiving something differently than it actually exists, so what we see does not correspond to physical reality. The word illusion comes from the Latin verb illudere meaning, "to mock." In addition, some illusions show us one thing in a picture, while someone else sees something entirely different in the same picture.
