Rotating Light
Source Institutions
In this activity, learners explore what happens when polarized white light passes through a sugar solution.
Spherical Reflections
Source Institutions
In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.
Water Illusions: Refraction & Magnification
Source Institutions
Learners demonstrate how water can distort, refract and magnify light.
The Liquid Rainbow
Source Institutions
Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.
Hot Spot
Source Institutions
In this activity, learners explore the invisible infrared radiation from an electric heater.
Critical Angle
Source Institutions
In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.
Forensic Science: Hair Sample Investigation
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Forensics) is a full inquiry investigation into how hairs from a crime scene are matched to suspects.
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.
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.
Convection Current
Source Institutions
In this activity, learners make their own heat waves in an aquarium.
Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.
Super Sleuths
Source Institutions
In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection
Luminescence
Source Institutions
In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.
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.
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.
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
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.
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.
Infrared Investigations
Source Institutions
In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.
