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.
Laser Jello
Source Institutions
In this activity, learners use gelatin as a lens to investigate the properties of laser light.
Make a Green Gumball Black
Source Institutions
In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!
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.
Structure of Matter: Pigment vs. Iridescence
Source Institutions
This is an activity (located on page 3 of the PDF under Butterfly Wings Activity) about how visible light is affected by tiny nanoscale structures, producing iridescence on butterfly wings, soap bubbl
On the Fringe (formerly Bridge Light)
Source Institutions
In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.
Rainbow Glasses
Source Institutions
In this activity, learners explore light, color and rainbows by making their own rainbow glasses.
Turbidity
Source Institutions
This is an activity about turbidity, or the amount of sediment suspended in water.
Pixel Tube
Source Institutions
In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.
Mix-N-Match Light
Source Institutions
This is an online exhibit about color perception. Learners set a random background color and then try to mix red, blue, and green light to match.
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.
Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
The Old White Sheet Trick: Light and Insect Behavior
Source Institutions
In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.
Total Internal Reflection
Source Institutions
In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.
Tools of Magnification
Source Institutions
In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.
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.
Periscope
Source Institutions
In this optics activity, learners build a spy tool to secretly view things over walls or around corners.
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.
Sunblock Investigation
Source Institutions
In this "Sid the Science Kid" activity, learners set up a simple experiment to find out how sunscreen counteracts the effects of the sun.
