CD Spinner
Source Institutions
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.
Spherical Reflections
Source Institutions
In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.
Water Sphere Lens
Source Institutions
In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.
Magic Wand
Source Institutions
In this activity about light and perception, learners create pictures in thin air.
Diffraction
Source Institutions
In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.
Bird in the Cage
Source Institutions
In this activity about afterimages, learners explore what happens when receptor cells called cones in your eye's retina get tired.
Disappearing Glass Rods

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
Anti-Gravity Mirror
Source Institutions
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.
Afterimage
Source Institutions
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.
Moiré Patterns
Source Institutions
In this activity about light and perception, learners create and observe moire patterns.
Pinhole Magnifier
Source Institutions
In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.
Benham's Disk
Source Institutions
In this optics activity, learners discover that when they rotate a special black and white pattern called a Benham's Disk, it produces the illusion of colored rings.
