Happy Memorial Tuesday! We did not have school yesterday, so there was no Math Monday prompt. Instead, we were given this one. Today's Science Solutions blog assignment is to explain the pathway that light takes to get to our eye starting from the cornea and ending with the brain.
When light hits our eye, it goes through the cornea and makes its way quickly to the lens of our eye. "Lens" comes from a Latin root that means "light", and as you might have been able to tell, it is what processes light. After going through the lens, the light goes through our eyeball at its signature speed until it becomes a signal. This signal is perceived by our brain as heat or color. Our minds, however, can only see and process a very small part of the electromagnetic spectrum of light. It uses this specified process to "read" the light. The signal spreads around your brain to let you know that what you're seeing is color. Sight is one of five senses, and in reality, all five of the senses are perceived by our brain because of the signals they trigger. Our brain works incredibly fast to have all five senses intact.
This blog prompt actually ties in with our previous unit, which was on light and optics. I wasn't here for the test, so I have to take it tomorrow. This is one of my favorite things to learn about in science and it always has been. Like other concepts and material we've learned in Science, this subject can tie into many other ones. The mechanics of the brain are under the topics of neuroscience and neurology, even though we were studying optics at the time that we learned this. Another cool part about learning this sort of thing was the dissection we did a few weeks ago. We found an example of this principle using the eye of a sheep. Their eyes are built in a way that is similar to ours, and their brains send signals the same way that ours do. Right now we're doing another dissection, only this one does not tie into a greater unit; we're finding out how the inside of a frog works by doing a virtual and then a literal dissection.
