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 conduct the "Stroop Effect" test and explore what happens when they try to complete two simple tasks at the same time.

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 (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.

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.

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

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

In this activity, learners conduct a simple test to find their blind spot.

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.

In this activity (13th on the page), learners complete a simple illusion trick to see through their own hand.

In this activity, learners calculate the width (horizontal diameter) of the blind spot on their retina. Learners make a blind spot tester using a piece of notebook paper.

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

In this activity (1st on the page), learners keep a "SLOG" or Sleep Log to study their sleep patterns.

In this activity (1st on the page), learners find their blind spot--the area on the retina without receptors that respond to light.

In this activity (1st on the page), learners explore circadian rhythms by keeping track of their body temperature.

These two activities (4th on the page) demonstrate the importance of two eyes in judging depth.

In this activity (1st on the page), learners conduct a series of tests to find out which of their hands is more dominant. In other words, are they right-handed or left-handed?

In this activity (18th on the page), learners conduct an experiment to examine memory.

In this activity (23rd on the page), learners conduct an experiment to examine memory and learning.

In this activity (on page 146 of the PDF), learners will explore the effects of increased carbon dioxide in the bloodstream.
