Seeing 3DAdd to list Details
Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!
CD SpinnerAdd to list Details
In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.
Shark Sense of SmellAdd to list Details
This is an activity about our sense of smell and how it compares to sharks' super noses. Learners will create varying solutions of water and perfume.
PupilAdd to list Details
In this activity, learners explore their eye pupils and how they change.
Drugs, Risks and the Nervous System
In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.
Blind SpotAdd to list Details
In this activity, learners conduct a simple test to find their blind spot.
Seeing Your RetinaAdd to list Details
In this quick optics activity, learners use a dim point of light (a disassembled Mini MagLite and dowel set-up) to cast a shadow of the blood supply in their retina onto the retina itself.
Magic WandAdd to list Details
In this activity about light and perception, learners create pictures in thin air.
Hole in Your HandAdd to list Details
Create an illusion where it appears that your hand has a hole in it. You'll see the results from when one eye gets conflicting information.
Depth SpinnerAdd to list Details
Experience a spinning spiral...you won't be hypnotized, but you'll see what happens when you look away. It's like getting off a merry-go-round and everything keeps moving.
Jacques Cousteau in SeashellsAdd to list Details
Up close, an array of dots could look random, but take a step back, and an image forms. By tracing over an image, learners can create their own dot based image.

In this activity about afterimages, learners explore what happens when receptor cells called cones in your eye's retina get tired.
Fading DotAdd to list Details
In this activity, learners play with a fuzzy-colored dot that has no distinct edges seems to disappear. As learners stare at the dot, its color appears to blend with the colors surrounding it.
Lateral InhibitionAdd to list Details
Which one of your eyes are dominant? Do they act independently or are they equally "in control?" This activity explores how your eyes work (or don't work) together.
Size and DistanceAdd to list Details
In this activity about depth perception, learners create an optical illusion in a shoe box.
Don't Be Nerve-ous
In this activity, learners discover a brain process called habituation.
Color ContrastAdd to list Details
Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.
How Our Environment Affects Color Vision
In this lab (Activity #1 on page), learners explore how we see color.

In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side.
AfterimageAdd to list Details
In this activity about light and perception, learners discover how a flash of light can create a lingering image called an "afterimage" on the retina of the eye.
