In this activity, learners investigate color vision as well as plan and conduct their own experiments.
In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.
In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.
In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.
In this activity, learners calculate the width (horizontal diameter) of the blind spot on their retina. Learners make a blind spot tester using a piece of notebook paper.
In this activity (1st on the page), learners find their blind spot--the area on the retina without receptors that respond to light.
In this optics activity, learners conduct an experiment to find out why two eyes are better than one!
In this activity, learners investigate the sense of sight and develop and conduct their own experiments.
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.
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.
In this activity (13th on the page), learners complete a simple illusion trick to see through their own hand.
In this activity, learners create an optical illusion by spinning two attached cups. A round ball seems to magically appear when the cups spin.
In this activity, learners investigate visual perception as well as plan and conduct their own experiments.
Design and create an optical illusion toy that makes two pictures appear to become one. This is called a thaumatrope and will allow the learner to investigate the phenomenon of persistence of vision.
In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.
In this activity, learners make a Benham Top to explore visual illusions and optics.
In this easy demonstration (3rd on the page), learners explore depth perception by conducting a test with two pencils.
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.
In this activity, learners surprise their eyes with an optical illusion involving arrows made out of pipe cleaners.
