Blind Spot
Source Institutions
In this activity, learners conduct a simple test to find their blind spot.
See It to Believe It: Visual Discrimination
Source Institutions
In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.
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.
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
X-Ray Vision?
Source Institutions
In this activity (13th on the page), learners complete a simple illusion trick to see through their own hand.
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.
Afterimage
Source Institutions
In this activity about vision and optical illusions, learners conduct a simple test to demonstrate how our eyes create "afterimages." Learners stare at a black cardboard bat for at least 30 seconds an
Magic Disc
Source Institutions
In this activity, learners create an optical illusion by spinning two attached cups. A round ball seems to magically appear when the cups spin.
Our Sense of Sight: How We Perceive Movement, Depth and Illusions
Source Institutions
In this activity, learners investigate visual perception as well as plan and conduct their own experiments.
Arrows
Source Institutions
In this activity, learners surprise their eyes with an optical illusion involving arrows made out of pipe cleaners.
Drop IT!: Depth Perception
Source Institutions
These two activities (4th on the page) demonstrate the importance of two eyes in judging depth.
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.
Afterimage
Source Institutions
In this optics activity, learners investigate afterimages.
