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

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.

Paint by the Numbers
Source Institutions
In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects 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.

Kaleid-o-mania
Source Institutions
In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.

Illuminating Luminescence
Source Institutions
In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.

Sliding Gray Step
Source Institutions
How can you make one shade of gray look like two? By putting it against two different color backgrounds! This activity allows learners to perform this sleight of hand very easily.

Slide Projector Activities
Source Institutions
This resource contains several mini-explorations using a slide projector as a light source to investigate light and the properties of images.

Finding the Size of the Sun and Moon
Source Institutions
In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

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

Sensory Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

Writing for Night Vision
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl

Laser Projection Microscope
Source Institutions
In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

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.

Wintergreen
Source Institutions
In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

Blue Sky
Source Institutions
In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.
