The dress only appeared to be different colors in one photo. Do you think anyone will ever be able to take another photo like this? Why or why not?
How likely do you think it is that designers will attempt to create more color-changing clothing? Do you think they’ll succeed? Why or why not?

- Ask the class: Is it possible for your eyes and brain to disagree? If so, which would you believe — your eyes or your brain? Discuss the possibilities. Challenge students to give good reasons for whichever option they chose.
- Display a video to teach students about optical illusions.
- Then access the Smithsonian magazine article "These Patterns Move, But It’s All an Illusion." Double click on each image to display the pattern full-screen.
- Encourage students to describe what they see. Challenge them to explain how and why that’s different from what their brains know. Brainstorm reasons why students think this phenomenon might occur.
- Give each student a piece of plain white paper and access to markers. Then follow a lesson plan and invite students to create their own optical illusions.
Invite students to share their drawings with the class. Instruct them to identify what their eyes see and what their brains know. Challenge students to pinpoint elements in their drawings that cause their eyes to misinterpret the information.
