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

In this activity, learners dissect a piece of pizza to learn about nutrients important for health.

In this activity (4th activity on the page), learners use their sense of smell to rate and arrange containers filled with different dilutions of a scent (like cologne or fruit juice) in order from wea

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

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

In this activity (17th on the page), learners investigate why you cannot see colors in dim light.

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.

In this quick activity/demonstration (5th on the page), learners explore depth perception.

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.

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 activity (3rd on the page), learners investigate circadian rhythms by examining how well people do with estimating time.

In this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp-poi

In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.

This mirror-tracing activity related to proprioception is a visual and motor test that involves learning a new motor skill.

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.

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 and game, learners will train to improve balance and spatial awareness by performing throwing and catching techniques on one foot.

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

In this activity about sleep rhythms (on page 25 of the PDF), learners will investigate how changing the time they go to bed impacts their own sleep patterns.

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