Our results show that when we gradually got farther away from our colored bars, the colors started to fade. We found that the red had gotten darker and the blue had gotten brighter. At eight feet the red was increased by fifty percent.

Our experiment was to measure the color in water and how the color changes. When looking at our average results of two spots on the colors, the red had started to get darker. This meant that our research matched our results. But after we had done all of our trials up to eight feet, the red started to get darker. This may have been due to the artificial lighting in the pool which caused uneven lighting of the bars. The pool’s lighting is different than the lighting might be in the ocean. Another analysis of error, that we found, was that the water started to seep through to the colors a bit. Even though we did not use that part of data, and we used a part of the color that was not wet. After we developed the pictures, we found that the pictures did not come out. Fortunately Mr. Harlan had taken some video footage of our project, so we used that data. The problem with that is, the camera automatically fixes the color, or blurriness, if the frame isn’t clear. So there is also some error in that. The frames we used were color adjusted and therefore isn’t the same as we could see it. Another thing is that if you look at any pictures underwater, they are very blue and you can barely see the red. Here is a picture that show’s this.

 

 

These results predict that when going deeper than the seventeen feet in a pool, the colors may change drastically and may even not show up as the same color as before.

When doing this experiment, I have learned many new things that I would not have known. For example, i never knew that colors had different wave lengths, and how they changed when going underwater. I always thought that when underwater, there may be some change in a color, but it wouldn’t look too different. Even though our results didn’t change drastically, that doesn’t mean that they wouldn’t change if we went deeper into a situation. I also learned that it is very hard to figure out how to put all of your data into words/ graphs and tables. It is also very hard to analyze your error into word when all you see are graphs and tables. This is a very hard thing to do and I am glad that we could do this experiment ourselves to experience what it was like scuba diving.

 

 

 

Claire's Essay:

Our results showed us many different things. We chose to use only 4 colors; red, orange, yellow, and blue. With color red with the amount of red saturation in it, the farther away you got from the box, the higher the number got. This does not mean that red well necessarily drop out, but the red will not look like red anymore! The higher the number got on the graph, the brighter the color gets.With the amount of green in the color red, the same thing happened, at 8 feet the color hue was 43, and from 2 feet it was 24 and lastly, with blue mixed in the red, it did again the same thing! With these dark colors, the light is harder to get to from farther distances, so the color that was originally there, may now look like a different color, just like the red up above! The color hue means how much of a certain color is in another color. For example, how much yellow is in the color green. Now, moving on to the color orange.This color orange, is a very bright, and light color, so the light is much easier to reflect off of, or too see. The farther away you got from the box, the lighter the color got. However, when the blue was mixed in with the orange, the farthest away was also the darkest. Our next color, was yellow. From both 2 feet and 8th feet, the color was 64,m or 64.5. On the other hand, the rest of the results seemed to be the farther away you got from the box, the lighter the color got. Lastly, was blue. The farther you got away from the object, the darker the color seemed to get. The red incorporated with the blue at 2 feet was 59.5, but the same thing at 8 feet was 78. Also, the blue and blue at 2 feet was 113, and at 8 feet it was 114.5. It seems that the colors that dropped out or lightened up the farther you got away from them , was just orange. We think that some of our results, were misfigured on account of the fact that we were in a pool that was artificially lit, and we were about 8 feet underwater.

We had many challenges in this D.E.E.P project! Our first challenge was at my house. We had constructed our experiment, and it was ready to be descended into the water. We got ourselves in the pool, and then with the help of our parents, we got the box in. But how were we to hold the box under water? We hen thought of sandbags, buy at the time we didn’t have them. Our next challenge, was finding out how to measure color. We worked really hard, looking at all of the programs on the computer. We finally, found our solution in Photoshop Elements. We could click on a section of the picture, and find out the hue, saturation, and the brightness, and the amoutn of red, green, and blue in each color.Our next challenge was about ten minutes into our experiment, when he water began to seep through the laminated paper! This error would most definitely affect our project. Another challenge and thankfully our last, was our difficult with film development. When we were down in Long Beach, our experiment was a success, but we were yet to know that the underwater camera film was not going to develop. We resolved our first challenge (the sandbags), by buying some from our local hardware store, and brought them to Long Beach. Our second challenge was a most easy to fix; all we had to do ws cut up more paper, laminate it, and glue it to the box. On the other hand, not being able to get our photos developed was a HUGE problem. Fortunately, we had a backup plan. Our science teacher, Mr. Harlan, took video footage of our experiment at the Long Beach Olympic Pool. He set the video camera at two feet, four feet, 6 feet, and eight feet, pausing for a moment at each spot. We were therefore able to use i-move to get the still photos of the images at the certain distances.

During this D.E.E.P project, we had a few sources of error. When you are in a pool, there are walls keeping the water inside. This definitely affected our D.E.E.P project. Since our experiment was done in a pool, the light bounced off the walls of the pool. Therefore, when we took the pictures, the light was hitting our color bars unevenly. We got our data from video footage in Long Beach, so the fact that the video camera automatically adjusts the color, our data may have been a little off. When we got the pictures, we did two trials. We chose two different spots for each color, and then found the average of them. Since the light was hitting the color bars unevenly, one color may have been brighter or darker than the other.
