How Do We See Color?

Published on August 29, 2022 by

The color of any object we see is just how our brain understands the light bouncing off it.  In this lesson, students will understand how we perceive color. When light bounces off an object, some of it enters the eye, where the cones in the retina begin working. The human eye has three different types of cones to perceive red, green, and blue light. If any of them is missing, we say that the person is colorblind. Dogs have only two types of cones, whereas the mantis shrimp has twelve to sixteen types of cones.

The video satisfies the 4-PS4-2 requirement of fourth-grade science proficiency.

Students who demonstrate understanding can: 4-PS4-2. Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.
