Analytic Essay


Our experiment has allowed us to explore different aspects of vision above and below water. The results that were gathered from our experiment have been very interesting. After analyzing the errors in the experiment, we found numerous ways to decrease the error in the experiment. When analyzing the results, we decided they can help predict other situations under water. Ideas for further studies were brought up. Many things could be learned from this experiment that contribute to one's understanding of vision in different circumstances.
The results from the experiments taught us many things. We learned that objects appear thirty three percent larger area under water. Another concept that we became educated about was that the farther away an object is the smaller the object appears. Testing underwater vision was essential for understanding how vision relates to scuba diving. The most popular reason to scuba dive is to see underwater life. It is important to the scuba diver to know what the actual size of object they see. One needs to know how big things are so they know if they can fit between them. An example of this is that one would need to know how large a cave is so they do not try to go through it and get stuck. These are only some of the ways that underwater vision relate to scuba diving.
After completing the experiment we analyzed our error. After looking at our results we found many things that were not what they should have been. The two main problems were that the objects moved and our measurements were not exact enough. Instead of holding each object at every distance of the board we should have had them taped to the board so they could not move. That way on each board there could have been one object at a different distance. We should have had twelve different boards and four of each object because it would be more convenient. This change would make the objects always stay in the same place. Also, we should have been more exact with our measurements of the pictures by not rounding. We could have used a smaller unit of measurement like millimeters. These changes would help make our results more reliable.
If one predicts other situations underwater our results could be helpful. They helped us conclude that if one were to go into deeper water there would be less light; therefore, one would not be able to see things as well. There are many reasons why there is not as much light deeper in water (link to background essay). This experiment helped support the concepts in our background essay.
There are many other experiments one can do for further studies of underwater vision. One could try doing our experiment at different depths such as 10 feet underwater, 20 feet underwater to 100 feet underwater. This could help show the changes in one's perception of an object at different depths. One could use different shaped objects to see if the shape of an object affects one's perception of the area of that object. One could also use different colored objects to see is color changes ones perception of the area of an object.
We learned many things from this process. Objects appear thirty three percent larger under water. The farther away something is the smaller it appears both above and below water. If one does not wear a mask underwater, objects appear blurred. This experiment proved our hypothesis but there were some errors could have made our results inaccurate.
