Crossing the Synaptic Gap
Source Institutions
In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.

Right Foot/Left Foot
Source Institutions
In this activity (2nd on the page), learners conduct a series of tests to find out which foot is more dominant. In other words, are they right-footed or left-footed?

Dark Adaptation
Source Institutions
In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.

Colors, Colors?
Source Institutions
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

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

Half Full or Half Empty
Source Institutions
In this activity (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.

Auditory Acuity
Source Institutions
This activity (8th activity on the page) tests learners' ability to identify things using only the sense of hearing.

How Fast Are You?
Source Institutions
This activity is designed to let learners measure their reaction time or response time to something they see.

Head, Shoulder, Knees and Toes...and Hands, Fingers and Back
Source Institutions
Are fingers the only place on the body where we use our sense of touch? In this activity (6th activity on the page), learners test the touch sensitivity of different parts of the body.

Depth Perception
Source Institutions
In this easy demonstration (3rd on the page), learners explore depth perception by conducting a test with two pencils.

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

Think Fast!
Source Institutions
This is a quick and simple demonstration about reflexes (fourth activity on the page). One learner stands behind a see-through barrier like a window or wire screen.

A Penny Saved is a Penny Heard
Source Institutions
In this activity (11th activity on the page), learners use pennies to test their hearing acuity.

Accommodating Accommodation
Source Institutions
In this demonstration (18th on the page), learners conduct a simple test to explore how the cornea refracts light, which is further bent by the eye lens through a process known as accommodation.

Shifting Backgrounds, Shifting Images
Source Institutions
In this quick activity/demonstration (5th on the page), learners explore depth perception.

Built in Stopwatch
Source Institutions
In this activity (3rd on the page), learners investigate circadian rhythms by examining how well people do with estimating time.

Jump to It!
Source Institutions
This is a quick and simple demonstration about reflexes (second activity on the page).

Knee Jerk Reflex (Patellar Reflex)
Source Institutions
In this quick and simple activity about reflexes (third activity on the page), learners conduct a simple test to explore the knee jerk reflex, typically conducted at the doctor's office.

Pupil to Pupil
Source Institutions
In this quick and simple activity about reflexes (at the top of the webpage), learners conduct a simple test to explore pupillary response.

Sock It To Me!
Source Institutions
In this activity (7th activity on the page), learners use their sense of touch to identify mystery objects hidden in socks.
