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.

During this activity, learners take part in a variety of tasks which involve moving and balancing different body parts.

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

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

In this activity (3rd on the page), learners conduct a series of tests to find out which of their eyes is more dominant.

This activity is designed to let learners measure their reaction time or response time to something they see.

In this activity (9th activity on the page), learners work in pairs to see how their perception of touch differs from reality.

In this activity (10th activity on the page) about the sense of touch, learners make Braille letters out of cork or cardboard and map pins.

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.

In this activity, learners construct a three-dimensional ambiguous cube to explore visual illusions and how our brains interpret or misinterpret information.

In this activity related to the famous "Stroop Effect," learners explore how words influence what we see and how the brain handles "mixed messages." Learners read colored words and are asked to say th

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 (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.

In this activity (5th activity on the page), learners explore how what you see influences taste. In experiment 1, learners taste five sodas, one of which is clear soda with orange food coloring.

In this activity (4th on the page), learners conduct a series of tests to find out which of their ears is more dominant.

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 (11th activity on the page), learners use pennies to test their hearing acuity.
