Rainbow Refraction
Source Institutions
In this activity, learners will explore how light can refract or break apart into different colors.
Changing Colors
Source Institutions
In this activity, learners will explore how different colors of lights interact with objects around them. Will a blue object stay blue with a red filter?
Morphing Butterfly
Source Institutions
In this activity, learners explore how nanosized structures can create brilliant color.
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.
Soap Bubble Shapes
Source Institutions
Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.
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.
Pinhole Magnifier
Source Institutions
In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.
Shadow Puppets
Source Institutions
If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.
Nebula in a Jar
Source Institutions
In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.
Up Periscope!
Source Institutions
This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.
Shadow Puppets
Source Institutions
In this activity, learners will create their own simple shadow puppets, and experiment with light and shadow while playing with them.
Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.
Optical Morpher
Source Institutions
In this amazing activity about light and reflection, learners will use a pie plate and reflective strips from a mylar balloon to try to morph their face into a friend's.
Shadow Dance
Source Institutions
In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.
Exploring Structures: Butterfly
Source Institutions
In this activity, learners investigate how some butterfly wings get their color.
Reflecting Rainbows: Decorate Your White Walls With Rainbow Colors!
Source Institutions
Like water drops in falling rain, a CD separates white light into all the colors that make it up.
Bubble Tray
Source Institutions
In this activity, learners use simple materials to create giant bubbles.
DIY Sunprints
Source Institutions
In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.
The Three Little Pigments: Science activity that demonstrates the primary and secondary colors of lightScience activity that demonstrates the primary and secondary colors of light The Three Little Pigments Know your C, M, Y, and K.
Source Institutions
Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.
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.
