Purpose:
Beforehand Research: We were required to do research about eye dilation before conducting the experiment.What we researched/learned?:
Materials/(Research):
What Happened? Another Eye story This was going to be more difficult than the other eye experiment. We were very excited to see how the eye would look dilated. But the problem was that an eye only dilates in the dark, and how do we get footage or document something that is in the dark? Photos or videos won't show up in the dark! We chose Griffin as our eye model, for we found his eye the most intricate out of the ones in the previous project we did. Our first idea was to go into a dim room in the school with dim lights to meet the best of both worlds. We thought that taking a video in a dimmed room may give the same effect as if it were a really dark room. It was extremely difficult trying to manipulate the eye to dilate. We'd have our eye model sit down in a chair in the recording room and since the room had adjustable lights, we'd start off with the room dim and then slowly turn the bright light up to watch his eye go from dilated to not dilated. We failed numerous times as I couldn't function the lights correctly, and the room was still to dark for Sammie to take a high quality video. The only video we got was blurry and dark. So we decided to change plans. We went outside near the other exit/entrance of the school near Nick's room. We saw as Grffin faced the doors, his eyes came out really clearly in the camera. We then suggested him to close his eyes for about 30 seconds or so, to manipulate the eye into dilating. We weren't sure if it would work, but on 3 we would ask him to open his eyes, recording all of it in the process. We were hoping to capture his eye slowly stop dilating. We watched the video that Sammie had took and we saw the pupil change from dilated to not. Amazed, we tried again, asking Griffin to keep his eyes shut for an even longer amount of time now. We took another video and noticed that it didn't have the same effect as the first one. We were left confused. Griffin then realized that in the first video, I had been standing in front of the door, blocking direct light exposure to his eye when he opened it. Knowing that, we tried another video, this 3rd time with me standing in front of Griffin. After taking the video, we happily looked at it. Noticing that the eye successfully went from being dilated to not being dilated. It came perfectly in the video and Sammie even slowed it down even more with an app to point out more of a significance difference in the transition. HERE IS THE VIDEO! ORIGINAL (NORMAL SPEED) BELOW IS NOT OUR FINAL PRODUCT FINAL PRODUCT (SLOWED DOWN) IT IS OUR FINAL PRODUCT. What I learned/Noticed?:
I had a few questions on this topic after the experiment. I noticed things that weren't ever explained. These are questions that I had in the aftermath.
Your pupils can also constrict and dilate as a result of a variety of medicines and drugs. In fact, doctors will often shine a light into a patient’s eyes to test the reaction of the pupil to determine whether the body appears t

What I enjoyed? Seeing someones eye dilated! It's so different from what I'm used to and it looks so much more interesting when the pupil is larger than usual. I was glad that we were able to find a solution to our "darkness" problem. We thought we needed complete darkness and we thought that filming an eye dilate in the dark was impossible. But we worked around those struggles and found a good way to push through. Group Work? I feel like Sammie and I worked together really well. We carried out all responsibilities in this assignment and we both gave up blogging time to carry out with the experiment. I hope we can work together again!
