Optical Illusions

Create a book or poster showing at least 5 different optical illusions.

• Each illusion will need an explanation which tells the viewer what he/she is to do. This can be phrased as a question such as “Which is longer?”
• Neatness counts—use a ruler to draw straight. Use a compass to draw a circle or trace around something round.
• Use color—optical illusions are visual. Make your project visually appealing.
