Moiré Patterns
Source Institutions
In this activity about light and perception, learners create and observe moire patterns.
Colored Shadows
Source Institutions
In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.
Phantom Phlame
Source Institutions
In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.
Soap Bubble Shapes
Source Institutions
Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.
Pupil
Source Institutions
In this activity, learners explore their eye pupils and how they change.
Magic Wand
Source Institutions
In this activity about light and perception, learners create pictures in thin air.
Hot Spot
Source Institutions
In this activity, learners explore the invisible infrared radiation from an electric heater.
Corner Reflector
Source Institutions
In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.
Polarized Sunglasses
Source Institutions
In this activity, learners explore how polarizing sunglasses can help diminish road glare.
Touch the Spring (Lightbulb)
Source Institutions
In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.
Glow Up
Source Institutions
In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.
Giant Lens
Source Institutions
In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.
Bone Stress
Source Institutions
In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.
Up Periscope!
Source Institutions
This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.
Reflecting Rainbows: Decorate Your White Walls With Rainbow Colors!
Source Institutions
Like water drops in falling rain, a CD separates white light into all the colors that make it up.
Bubble Tray
Source Institutions
In this activity, learners use simple materials to create giant bubbles.
Cylindrical Mirror
Source Institutions
In this activity, learners create a cylindrical mirror to see themselves as others see them.
Seeing Your Retina
Source Institutions
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.
Look Into Infinity
Source Institutions
Learners use two mirrors to explore how images of images of images can repeat forever.
The Three Little Pigments: Science activity that demonstrates the primary and secondary colors of lightScience activity that demonstrates the primary and secondary colors of light The Three Little Pigments Know your C, M, Y, and K.
Source Institutions
Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.
