Baffling Body
Source Institutions
In this activity, learners will learn about proprioception, or the body's sense of its place and position in space.

What's the Buzz?
Source Institutions
In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.

Size and Distance
Source Institutions
In this activity about depth perception, learners create an optical illusion in a shoe box.

Disappearing Glass Rods
Source Institutions
In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of

Don't Be Nerve-ous
Source Institutions
In this activity, learners discover a brain process called habituation.

Giant Lens
Source Institutions
In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.

Musical Coat Hangers
Source Institutions
Discover how sound travels and what materials make better sound conductors. Can you hear better with your fingers in your ears? Find out with a coat hanger and some string!

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

How Our Environment Affects Color Vision
Source Institutions
In this lab (Activity #1 on page), learners explore how we see color.

Bubble Sculpting
Source Institutions
In this activity, learners develop spatial reasoning skills as they blow bubbles and observe what happens when the bubbles connect.

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

Eyepatch Challenge
Source Institutions
In this activity, learners construct an indoors obstacle course and discover how using an eye patch can help them complete the course in the dark.

Body Biographies
Source Institutions
In this activity, learners will learn about a person they admire (famous, family or otherwise) or even themselves and create a life-sized silhouette.

Stereo Hanger
Source Institutions
In this activity, learners investigate sound wave science, in stereo! Learners construct a "stereo" out of a metal coat hanger and piece of string to explore sound vibrations.

Penny Cup Game
Source Institutions
In this optics activity, learners conduct an experiment to find out why two eyes are better than one!
What's in the Bag?
Source Institutions
In this activity, young learners use their sense of touch rather than sight to identify a mystery object in a bag. Learners take turns acting as "peekers" and "sensers" throughout the game.

Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

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

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.

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.
