Polarized Light Mosaic
Source Institutions
In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

Three Circles of Pigments
Source Institutions
In this activity, learners overlap the three primary colors to see how all other colors are made.

Release the Rainbow
Source Institutions
In this activity, learners create a water prism to break light into the seven colors of the rainbow.

Bending Light
Source Institutions
In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

Shimmering Lenses
Source Institutions
In this activity, learners use Jell-O to explore lenses. Learners cut Jell-O into convex and concave lens shapes and examine how light exits each lens in a darkened room.

Bronx Cheer Bulb
Source Institutions
In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu

Glue Stick Sunset
Source Institutions
In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.
Guiding Light
Source Institutions
In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

First Impressions
Source Institutions
Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

Star Power
Source Institutions
In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.

CD Spectroscope
Source Institutions
In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.

Kaleidoscope
Source Institutions
In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

Parabolas: It's All Done with Mirrors
Source Institutions
In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

Your Father's Nose
Source Institutions
In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.

Rotating Light
Source Institutions
In this activity, learners explore what happens when polarized white light passes through a sugar solution.

Beam Me Up!
Source Institutions
This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

Inverse Square Law
Source Institutions
In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

Observing Insects at Night
Source Institutions
In this activity, learners set up a night time insect observation station with a light and sheet.

Soap-Film Interference Model: Get on our wavelength!
Source Institutions
By making models of light waves with paper, learners can understand why different colors appear in bubbles.

See the World Through Color-Filtering Lenses
Source Institutions
In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.
