The Study of Color Wavelength Variation
Abstract:
While studying waves, our group was interested in color - and it's natural phenomenon. With this interest we decided to study color and how it attracts the human eye. We did an experiment that consisted of having people look into a dark box that had a color strip in it and then shown a bright light into the box. After this we asked them what they saw and recorded their answer. In the end we found that colors with larger wavelengths are recognized easier than ones with smaller wavelengths. Our results may not be the most reliable because of problems with our experiments.
Introduction:
The purpose of our experiment is to learn how wave length affects one's initial reaction to a color. We were fascinated in the phenomenon of color and wanted to explore deeper into the connection between how wavelength effect pigments. In this curiosity we decided to look into wavelength and how different wavelengths attract the human eye. The basic knowledge we had for this was to learn about wavelengths of colors. In a lab from Live Physics they explain,”The order of colors in light, arranged from shortest wavelength to longest, is called the visible spectrum of light. The image below shows light's visible spectrum, which runs from violet to red. You might recognize the spectrum as the order of colors in a rainbow.” Also you have to understand that the human eye can only see the visible spectrum. NASA explains this in an article about color wavelength. It states, ”Our eyes are sensitive to light which lies in a very small region of the electromagnetic spectrum labeled "visible light". This "visible light" corresponds to a wavelength range of 400 - 700 nanometers (nm) and a color range of violet through red. The human eye is not capable of "seeing" radiation with wavelengths outside the visible spectrum.” We believe that colors with larger wavelengths be recognized easier than ones with smaller ones. This is because human eyes have more sensitivity to red than they do blue and red has a larger wavelength. So because of this we think larger wavelengths will be easier recognized.
Question and Hypothesis:
How does the variation of wavelength of a color affect one’s initial reaction to color?
If the wavelength of a color is larger, the test subject will recognize the color quicker because of the human eye's sensitivity to red color waves. to certain wavelengths and the sensitivity of specific colors.
Methods and Materials:
To create this experiment we took a black box and cut a hole in the top of it and also on two different sides. Then we printed out color swatches from the internet that had a variety of different color swatches. We cut these into strips so that there were different patterns of color to look at. We took eight test subjects into a dark room where we had the box setup with the color strips. These color strips had many different colors on them. The first had green, blue, pink, red, and yellow. The second had yellow, red, pink, purple, and blue. The third had red, orange, blue, light, blue, and green. We then had one test subject look into the box where we would turn on a flashlight quickly and then turn it off quickly. This quick flash of light meant that the test subject only had a moment to process the color before it went dark again. After this we asked the person what they saw and we would record that data. We continued these steps and after all eight people had seen the first strip of paper with colors on it we would change it out and put in the second and then the third.
Results:
After the experiment we looked at the data we collected and made some conclusions. It seems that the most recognized colors are red, pink, blue. Red was the most common color seeing as it was seen in the first two rounds people saw either red or pink which is just a shade of red. In the third round of the experiment there was an interesting contrast to the results from the first and
second round because every test subject saw either blue or light blue. In the end we found that red is the most easily recognized color and and that colors with larger wavelengths are seen easier.
Discussion:
Our results were not the most conclusive because our experiment was not refined as much as it could have been. Our results were that red was the most easiest recognized and the blue was second. These give some very interesting things to think about because red and blue are almost opposite on the color spectrum and have very different wavelengths. If we were to do it again we would have had more colored strips that very which colors are in the middle. If we had done this we could have gotten data that was more reliable. The problem with our experiment is that every color every one saw was either in the very middle or one to the side of the middle. This made it so that our data was not as accurate as it could have been and we can’t say that our results were completely correct.

Rube Goldberg

Rube Goldberge: A complex machine that does a simple task in many steps.
In this project we learned how to apply physics to a real world problem. We built Rube Goldberges to learn how different physics phenomenons effect things in the world. We learned equations and did labs to find how physics effects movement in an object . We also learned about energy and mechanical advantage to apply to our Rubes. After coming up with a plan for our Rubes we built them in teams of three. We had to write explanations of our Rube Goldberges with physics applications to each step. We deeply analyzed four step and explained them through physics explanations. Then we exhibited then to a community audience and ran the project through completely to show people what we learned. |
Phones= No sleep experiment
In this project we came up with our own experiments to conduct and learn through. We got to pick our own groups and our own topics so it made the project more fun. We had to create a question that was testable and had variables then we had to create a hypothesis based on this question. The groups were to then choose of method of testing our questions using either previous experiment results, survey, or an actual experiment. Then we would collect our results and see if our hypothesis was correct. In the end we made some sort of project to put out to a bigger community.
I think that I learned a lot through this project. Even though I think that my experiment wasn't the best I think that I came out with a lot o information that I can use in our next project. First of all I learned the usefulness of researching your topic completely. When I came to the end of my project I found that my results didn't give me the information that I needed to have conclusive results. I also found out that having a well thought out plan really helps to make an experiment go more smoothly. I think that I am now well equipped to take on the next project with confidence.
I also feel that this project helped me to grow in my use of digital resources. Since I used a survey as my method to obtain information I had learn how to use google survey. This was connected to google sheets so I had to expand my knowledge of using google sheets. These are helpful resources to have for when I want to collect more data for a different experiment. I can also use this skills in future jobs and projects.
Do Cellular Devices Affect How You Sleep?
By: Acacia Bryson
Abstract:
I asked the question How will the use of my phone affect how well I sleep? This was hard to test though so I changed it to how does the use of a cellular device affect one’s ability to fall asleep? I tested this through sending out a survey to my freshman class. My results found that more than half of people surveyed had trouble falling asleep and almost all people that had trouble falling asleep used their phones for at least an hour before bed.
Introduction: I researched how cellular devices affects sleep. I was thinking a lot about how I am affected by technology on a daily basis and inspiration hit when I was sleeping soundly and then my phone buzzed waking me from a peaceful slumber. This made me realize that using my phone could be hurting my sleep patterns. Thus I had the idea to find out if others had this problem too. When I researched my topic I found that the use of technology within close proximity to bed affects the melatonin production in your brain. Melatonin is a hormone produced in your pineal gland in your brain. It is the hormone that regulates sleep patterns. The use of devices that have a lit screen affects the body's production of melatonin. In an article from The Journal of Sleep Medicine say, “The more types of devices that you used, the more individuals reported difficulty falling asleep.” I used this to stem some of my research from. This was another study that was doing the same thing that I am doing. Also in the article Electronics in the Bedroom: Why it’s Necessary to Turn off Before You Tuck in they say that, ”Photoreceptors in the retina sense light and dark, signaling our brain about the status of the outside world and aligning our circadian rhythms(centered in a small region of the hypothalamus called the suprachiasmatic nucleus) to the external day-night cycle.” So basically when we use objects that have light it tricks our brains into thinking that day and that we don’t need to go to sleep. My research is to see if this is true.
Question and Hypothesis:
How does the use of a cellular device affect one’s ability to fall asleep?
If a cellular device is used before bed than the person using the phone will have trouble sleeping because of the light coming from the screen will affect the melatonin in their brain. .
Methods and Materials:
The method I used to test my hypothesis was to survey the freshman class. In this survey I asked about the students use of technology and sleep habit. My questions were:
After I wrote these questions I sent them out to 50 freshman though a google survey. I waited few days to give people answer my survey. When I felt that I had gotten all the responses that I was going to get I went into google sheets and found the percent averages from the answers I got. This made it easier to look at my data and find an answer for my hypothesis. I kept the age of people constant in this survey but I didn’t have very many other controlled variables. My independent variable was the use of cellular devices and my dependent variable was quality of sleep.
Results:
What I found with my result was very interesting. On average kids were getting 8 hours of sleep at night but 56% of them said that their phones were keeping them up later than their bedtime. Also 56% of people surveyed said they had trouble falling asleep at night and most of the people that said they had trouble falling asleep spent and hour or more on their phone before bed. On average I found that students are spending an average of 2 hour on their phones before bed. I did have a bit of trouble collecting this data mainly because I didn’t get a big of response that I wanted. Only 26 people responded which made for some slightly unreliable results.
Discussion:
I conducted this research to know not only how my peers but also how my sleep was being affected by using a phone before bed. I found that the use of your phone seemed to have an impact on your ability to fall asleep. I am not very confident in my results though for a couple reasons. First of all I didn’t have a whole lot of data to go off of so that kind of made getting a super accurate result hard. Second of all I didn’t think through my questions very well which meant that I didn’t have a very good result to look at. Lastly I don’t think that researched well enough to know what I was looking for in my results.
If I were to do this experiment again I would ask more questions about the type of things you do on your phone and how your quality of sleep is. My result do make sense when you look at other studies done on the same topic. Most of the studies I saw had similar result saying that using technology affects a person's ability to fall asleep and stay asleep. I also would have more control questions about already existing conditions like insomnia, Stress, or diet to know what else could have been affecting my results.
If my result are correct that means that my hypothesis would be correct as well, since my hypothesis was If a cellular device is used before bed than the person using the phone will have trouble sleeping because of the light coming from the screen causing them to not produce melatonin. I think that the result I have found can tell us that using technology before bed definitely had some effect on the body sleep. This will be useful to know because we can limit use of our phones before bed and start sleeping better.
