I teach AP Psychology and we just started the sensation section, which is one of my favorites. Well today we were talking about our vision sense and the different parts of the eye and things like that. I was telling them how we see, like how it literally all works and how it all connects to the brain. We talked about transduction (converting one type of energy into another basically) and how that is what happens in our eyes. We take in light energy through the various parts of our eyes to be picked up by the various receptor cells, etc.
All of that was going well and we were trucking along until we got to color. There are different color theories, two of which we discuss in class, but they both deal with the same thing: how we see color.
I showed them a picture of a red cartoon dragon. I posed the question, "what color is the dragon?" Of course they said "red" and then my annoyingly accurate response was "we see the red that is reflecting off of the dragon, but the dragon itself encompasses all the wave lengths except the red one." I went on to tell them that actually, the light energy has no real color, and the color that they are "seeing" is from their minds, and not on the actual surface.
It was at this point where my kids starting putting their hands on their faces, on their heads, up in the air, and looking at me like I was crazy. Comments were being made like "Mrs. Martin! You are blowing my mind!" and "Everything I have ever thought is wrong!" and "Did my Kindergarten teachers lie to me?"
hahaha... oh my gosh. Seriously. High school kids are so funny. I love their over the top dramatics... seriously. I really do.
Do I really need to say "vote for Eli" again? yes, yes I do :) Thanks friends!
