In this exercise (Activity #2 on page), learners test their distance vision to evaluate their overall eyesight.

This activity (on page 2 of the PDF under SciGirls Activity: Colorblind Dogs) is a full inquiry investigation into dogs' ability (or inability) to see color.

In this activity (3rd on the page), learners conduct a series of tests to find out which of their eyes is more dominant.

In this lab (Activity #1 on page), learners explore how we see color.

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, learners construct a device that allows them to view 2-D images in 3-D.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

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 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 easy demonstration (3rd on the page), learners explore depth perception by conducting a test with two pencils.

Make a camouflage cut-out animal! Using patterned paper or magazine pictures from around the house, use your craft skills to make a paper animal that blends into its background.

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

In this activity (17th on the page), learners investigate why you cannot see colors in dim light.

In this demonstration (18th on the page), learners conduct a simple test to explore how the cornea refracts light, which is further bent by the eye lens through a process known as accommodation.

In this quick activity/demonstration (5th on the page), learners explore depth perception.

In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.

Spin a short piece of PVC pipe that's been marked up, and watch a triangle appear. Enjoy this optical illusion from the Exploratorium's Science Snack series.
