Train Your Brain
Source Institutions
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.

Jumping to Conclusions
Source Institutions
In this online brain stumper, the bottom half of a series of letters is covered. You may think you know what it says, but remove the black bar to see if you're right.

Color Code
Source Institutions
In this activity, learners conduct the "Stroop Effect" test and explore what happens when they try to complete two simple tasks at the same time.

Phenakistascope
Source Institutions
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.

Building a Magic Carpet
Source Institutions
In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

Measuring Your Breathing Frequency at Rest
Source Institutions
In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

Building a 3-D Space Maze: Escher Staircase
Source Institutions
In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

Lateral Inhibition
Source Institutions
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.

Overlapping Spots: Make a bright spot brighter
Source Institutions
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.

Mirror, Mirror
Source Institutions
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.

Changing Body Positions: How Does the Circulatory System Adjust?
Source Institutions
In this activity about how the body regulates blood pressure (page 117 of the PDF), learners make and compare measurements of heart rate and blood pressure from three body positions: sitting, standing

Circles or Ovals?
Source Institutions
This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?

Tactile Mazes
Source Institutions
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.

Blind Spot
Source Institutions
In this activity, learners conduct a simple test to find their blind spot.

Shrinking Spot
Source Institutions
In this activity, learners control the (apparent) size of a hole with their brain.

The Braille Alphabet
Source Institutions
In this activity (8th activity on the page) about the sense of touch, learners make their own set of Braille letters. Learners use glue to make raised dots on a Braille Alphabet Sheet.

Memory Solitaire
Source Institutions
In this online game, learners practice memory recall. They are shown a collage of pictures for two minutes, then have to write down everything they remember and check how they did.

Model Eardrum
Source Institutions
In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

The Model Neuron
Source Institutions
In this activity, learners create a model of a neuron by using colored clay or play dough. Learners use diagrams to build the model and then label the parts on a piece of paper.

X-Ray Vision?
Source Institutions
In this activity (13th on the page), learners complete a simple illusion trick to see through their own hand.
