Introduction to optical illusions, part 1. For Middle School students and older.

This video is designed to help introduce Middle School students (or older students) to optical illusions. The focus is on being aware of these so that we can correctly interpret our senses and distinguish perception from reality. We point out why this is important in science as well as some daily activities (e.g., blind spots and driving).
