In this activity observe how light sources flash as you give them a raspberry. As you complete the activity, make a conclusion about what is wiggling the lights or you.

In this activity, you will trick your brain into thinking that your friend has disappeared except for their smile. Understand what happens when your eyes receive different images.

Did you ever wonder why you have two eyes but only see one image? This activity will explore how your brain combines the images from your eyes in surprising ways. Learn about the dominant eye and how some people do not have one!

This ScienceWorld site describes the Scottish mathematician and physicist James Maxwell (1831-1879) who published physical and mathematical theories of the electromagnetic field.

By using digitally manipulated images, test your brain to see how much information is needed for your brain to produce an image.

Here is an activity where students experiment with how the brain receives a strange view of a familiar object.

Did you know that different-colored backgrounds cause colored objects to look different? In this investigation, students will experience this phenomenon.

Observe adaptation and perception in the activity. This activity will have students watching a continuously rotation spiral to see what happens as you watch it and then look away.

An activity to test your perception to see if you can distinguish between different shades of gray.

Understand that what you see is often affected by your expectations of what you think you should see. This activity will explore the sensation you feel when your brain expects to see something.
