Fun with Science: Wacky Vision

In October, we explored one of the Syracuse CVR Lions’ favorite subjects—vision! We had such a fun time discovering how our visual system works and testing its limits.
To start, we sat down together and learned which organs are primarily responsible for helping us see: the eyes and the brain. We learned about the eye’s anatomical structure and found our own blind spot by covering our right eyes and staring at the “+” in the image below.
We reminded the children that if they ever find themselves struggling to see clearly, they should tell their parents/guardians or teachers so that they can get their vision checked by an eye doctor.
Next, we had fun exploring a number of optical illusions.
· We saw how our brain can interpret a concave face into a convex 3D structure (as shown in the “mask” video: see below).
· We demonstrated refraction by drawing fish and looking at them through a round glass with water.
· We used a homemade clear plastic pyramid to generate a 3D holographic image on our phone.
· We learned how our brain works to enhance the contrast of objects by comparing two grey circles over a gradient.
· We drew a fishbowl and a fish on opposite sides of a cardstock paper and alternated the images so quickly that it looked that the fish was inside the fishbowl!
· We also looked at fun books to trick our brains some more!
To make things a little spookier in the spirit of Halloween, we dissected cow eyes to learn more about the eye’s anatomic structure and function. What brave budding scientists we had!
