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, 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 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.

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.

These two activities (4th on the page) demonstrate the importance of two eyes in judging depth.

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.

In this activity, learners will explore how their own eyes work by experimenting with their photoreceptors.

In this artistic activity, learners blow up a smaller picture into a larger one, by using a grid.

In this optics activity, learners investigate afterimages.
