Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!
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.
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.
In this activity, learners explore their eye pupils and how they change.
In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.
In this activity, learners conduct a simple test to find their blind spot.
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.
In this activity about light and perception, learners create pictures in thin air.
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.
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.
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.
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.
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.
In this activity about depth perception, learners create an optical illusion in a shoe box.
In this activity, learners discover a brain process called habituation.
Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.
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.
