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.
Soap-Film Painting
Source Institutions
Make a big canvas of iridescent color with pvc pipe! In this Exploratorium Science Snack, you'll need to cut and assemble some PVC pipe, but the pay-off, the soap-bubble canvas, is big.
Magic Wand
Source Institutions
In this activity about light and perception, learners create pictures in thin air.
Hot Spot
Source Institutions
In this activity, learners explore the invisible infrared radiation from an electric heater.
Look Into Infinity
Source Institutions
Learners use two mirrors to explore how images of images of images can repeat forever.
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.
Self-Portrait Silhouettes: Activity 2
Source Institutions
In this activity, learners make a photographic image—without a camera!
Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
See the Light
Source Institutions
Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.
Bone Stress
Source Institutions
In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.
Anti-Gravity Mirror
Source Institutions
In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side.
Gray Step
Source Institutions
In this activity, learners discover that it's difficult to distinguish between two different shades of gray when they aren't separated by a boundary.
Self-Portrait Silhouettes: Activity 1
Source Institutions
In this activity, learners make a photographic image--without a camera!
It's all Done with Mirrors
Source Institutions
This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.
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.
