Seeing 3D
Source Institutions
Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!
Magic Wand
Source Institutions
In this activity about light and perception, learners create pictures in thin air.
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.
Peripheral Vision
Source Institutions
In this optics activity, learners conduct an experiment to explore peripheral vision. Learners collect data about their ability to see shapes, colors, or letters using their peripheral vision.
Motion Picture
Source Institutions
During this hands-on activity, learners are briefly exposed to moviemaking and animation, when they create their own thaumatropes.
Color Spy
Source Institutions
In this activity (16th on the page), learners play a variation of the "I Spy" game to explore color. Learners work in teams with each team assigned a color.
Afterimage
Source Institutions
In this activity about light and perception, learners discover how a flash of light can create a lingering image called an "afterimage" on the retina of the eye.
Phenakistascope
Source Institutions
In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.
Right Eye/Left Eye
Source Institutions
In this activity (3rd on the page), learners conduct a series of tests to find out which of their eyes is more dominant.
Seeing Your Blind Spot
Source Institutions
This activity (aka "snack") provides instructions for discovering your blind spot. It is an exploration of light and visual perception using simple materials you may have around the house.
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.
Thaumatropes
Source Institutions
In this activity, learners will make a thaumatrope, an old-fashioned optical illusion that dates back to the 1820s.
Whirling Watcher: Make a Stroboscope
Source Institutions
In this activity, learners make a stroboscope--a spinning disk with slits around the edge that you look through.
