This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

In this neuroscience activity (5th activity on the page), learners explore their sense of touch without using their senses of vision and hearing.

In this activity, learners play a trick on their own brain to see if the brain can learn to ignore distracting input. Colors and words are used to play the visual trick, known as a Stroop Test.

In this activity, learners discover a brain process called habituation.

In this activity, learners experiment with the Stroop Effect by challenging themselves and others to try and read a list of colors as quickly and accurately as possible, with a twist.

In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.

We don't normally view people upside down and so our brains aren't accustomed to it.

This is a quick and simple demonstration about reflexes (second activity on the page).

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

In this activity about depth perception, learners create an optical illusion in a shoe box.

In this activity (7th activity on the page), learners use their sense of touch to identify mystery objects hidden in socks.

In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

Which one of your eyes are dominant? Do they act independently or are they equally "in control?" This activity explores how your eyes work (or don't work) together.

This perception trick focuses on conflicting information to the brain...instead of trying to see two images, you're trying to get a bright spot by overlapping the image you see through two tubes.

In this activity, learners discover that it is difficult to trace a curve by using its reflection in a mirror. Use this activity to discuss how the brain works.

Known as the waterfall effect, this activity demonstrates adaptation in our visual system.

In this activity (15th activity on the page) about the sense of touch, learners use glue and cardboard to construct a maze they use with their eyes closed.

In this activity (3rd activity on the page), learners taste test different foods and categorize them as sweet, bitter, sour, or salty. Learners compare their results with the group.
