The Art of Optical Illusion
What do man-made illusions tell us about patterns in nature?
Introduction: Optical Perception
 

Optical Perception:

The essence of optical illusion comes from its play upon optical perception.  This lesson uses some optical illusions to begin the conversation about what we see and what we know.

Time: 20 minutes.


 Objectives:
  • Students will gain personal experience of optical illusions.
  • Through experience and demonstration the students will explore their prior knowledge of optical perception.
  • Students will learn how to store over-arching observations into a concept web graphical organizer.
 Materials:
 Activities:
  1. Begin with the optical perception sheet.  The discussion centers upon two separate illusory pictures.
  2. Put the discussion (prompt for feedback, and do not hesitate to put the words into the children’s mouths) into a concept web.
  3. This is a concept web to introduce the later concept webs germaine to the overall inquiry.  This web allows for training and teaching and highly scaffolded instruction.
  4. Take what they put into the web, and begin to outline the frequently used words list.
