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.

Views From Windows
Source Institutions
In this activity, learners use their imaginations and picture a scene in their heads.

Zoom: Travel to a Star and Back to Earth
Source Institutions
This is an online activity about what would happen if we could travel at or near the speed of light.

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.

Light and Dark
Source Institutions
Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

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.

Pearlescent Pigments
Source Institutions
This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

Amazing Albedo
Source Institutions
In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

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.

CD Spectrometer
Source Institutions
In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

Give and Take
Source Institutions
In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.
