Optical Illusions

LI: To explain what an optical illusion is.

This week, Mr Johnston came to LS2 to teach us more about optical illusions. Mr Johnston shows us some examples of optical illusions. One of them were two lines, where we decided which line was longer. Both lines were actually the same size. After learning about optical illusions, we learnt about Mc Escher and a piece of art he created. Then we created a DLO explaining, what an optical illusion is, who Mc Escher is and which line is longer.
