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.
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.
Become a Neurologist: Detective Threshold
Source Institutions
In this neuroscience activity (4th activity on the page), learners make their own set of Von Frey hairs to test detection thresholds.
Finger Reading
Source Institutions
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.
Magnification vs. Resolution: Can you see the flag on the Moon?
Source Institutions
This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.
Shape Stamping
Source Institutions
In this activity, learners will explore two-dimensional shapes that are found in three-dimensional shapes. Learners will explore geometry, design, color and tool use through this activity.
Size and Distance
Source Institutions
In this activity about depth perception, learners create an optical illusion in a shoe box.
Ocean Echolocation
Source Institutions
Use echolocation to find others and experience how whales’ senses have adapted to suit their environment. In pairs, learners are blindfolded and use containers filled with marbles to find each other.
Smell Detective
Source Institutions
In this activity about olfaction (8th activity on the page), learners smell 10 different items with different odors. Then they try to identify the smells when they are mixed together.
Tasty Buds

In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.
Find Your Way Around Without Visual or Sound Cues
Source Institutions
In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.
Adaptive Device Design
Source Institutions
In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o
