Mirrors and Images
Source Institutions
In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.
CD Spectroscope
Source Institutions
In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.
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.
The Ripple Tank
Source Institutions
In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.
Hole in Your Hand
Source Institutions
Create an illusion where it appears that your hand has a hole in it. You'll see the results from when one eye gets conflicting information.
Mix and Match
Source Institutions
In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.
The Bent Pencil
Source Institutions
In this optics activity, learners explore how light bends and affects what we see.
Why Are Bubbles So Colorful?
Source Institutions
In this activity, learners explore why they can see colors in bubbles and why they change.
Mirror, Mirror on the Wall: Angles of Reflection
Source Institutions
In this optics activity, learners work in pairs to explore how mirrors work. Learners use tape to mark the angles needed to see each other's reflection in a wall mirror.
The Blind Spot
Source Institutions
In this activity (1st on the page), learners find their blind spot--the area on the retina without receptors that respond to light.
Vanishing Rods
Source Institutions
This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.
Make a Light Fountain
Source Institutions
In this optics activity, learners make a "light fountain" from a clear plastic bottle, flashlight, and other simple materials.
What Causes Rainbows?
Source Institutions
In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.
Disappearing Glass Rods
Source Institutions
In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of
Color Contrast
Source Institutions
Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.
Splitting White Light
Source Institutions
In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).
Color Table: Color your perception
Source Institutions
Look at pictures through different color filters and you'll see them in a new way. People have used color filters in beautiful photography or sending secret messages.
Circles or Ovals?
Source Institutions
This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?
Make Money Appear Before Your Eyes
Source Institutions
In this optics activity, learners use water to make a coin "appear" and "disappear." Use this activity to demonstrate how light refracts and introduce light as waves.
Rainbow in the Room
Source Institutions
This activity generates learner excitement about light through the creation of a room-sized rainbow.
