Does Colour Relate to Temperature or Brightness?
Abstract:
The question that I chose to investigate was: Does colour relate to temperature or brightness? I chose this question because I was interested in the study of light waves, and colours. I had wanted to see if artists calling colours “warm” or “cool” was rooted based on fact, and if those colours were actually different temperatured light waves. To test this theory, I got a lamp with three different settings of brightness, which were 50 watts, 200 watts, and 250 watts. I also got a simple glass prism. Then, I turned off the lights, and blocked the windows, and turned the lamp onto it’s lowest setting. The white light passed through the prism, and was separated into individual colours. I tried this again with the second setting of brightness. The lightbulb got warmer, but the colours of the prism did not change. To make sure, I repeated the process with the third and highest brightness setting. The colours still did not change, although they were brighter. This concludes that the “warm” or “cool” colours are a myth, and that colour is not related to brightness or temperature.
Introduction:
Waves are vibrations of energy passing through a medium. An example of this could be sound waves passing through a speaker, radio waves passing from satellites to cell phones, or light waves passing from the sun through the air. My topic of study was light waves, and how these light waves can relate to colour. Visible light exists on a spectrum, with red light being easiest to see, and violet light being nearly impossible to see. So I have decided to see of colour relates to temperature. Artists and such are always saying “warm colours” and “cool colours.” What I want to know is if there is any truth to this.
Question and Hypothesis:
The question I have chosen to study is: Does colour relate to temperature? With the hypothesis of: If the light source (the temperature) is increased, then the colours will not change because it is just a myth.
Method and Materials:
The materials I used were a glass prism and a lamp with three different settings of brightness. I turned off all of the lights in the room and blocked the sunlight as best as I could, and turned on the lamp to the lowest brightness setting, with the prism in front of it.
Results:
The results were that all of the settings had the same colours, and the amount of light did not affect anything. The prism divides up the light, and does not only show certain colours. It’s all of them, or none of them.
Discussion:
I wanted to do this experiment because it seemed interesting and fairly simple to achieve. Light waves are very interesting to me, and I wanted to see if colours can change, as well as learn how a prism works. I didn’t really expect the colours to change, but I wanted to see if that was why colours are labeled with warm or cool. My hypothesis turned out right, and the colours did not change.

Design It Clean
Field Report
In Varanasi, India, the Hindu population, which is the majority, worship the Ganges River which is believed to be a god named Ganga. The Ganges flows through the heart of India down to the coast and is the largest river in the country. People bathe in it in order to cleanse themselves of sin. They also put the ashes of the deceased in the river so they can go to heaven. This rigorous use of the river is slowly hurting the it with harmful pollutants. In Varanasi many are suffering from extreme poverty and poor sanitation. This forces people to dispose of trash and even human waste in the river. Even as the political dynasty of India prospers, it’s largest sources of water is constantly being polluted. Another large pollution factor is the leather tanning industry. Heavy metals such as chromium, titanium and many others pollute the water. These all come from the process that is used to tan leather. This leaves harmful chemicals pouring into the Ganges. In addition, the ganges is suffering from the poor treatment it receives from the candles and plastic poured into the Ganges in large amounts. This is such a problem because the Indian people worship the Ganges every dusk and every night pollute the river more and more. |
Product Description
With an estimated cost of $6.00 our water filter will provide the people of the Ganges river with clean drinking and bathing water. Only needing any sort of water bottle ( that can be cut) cost is 50 cents to $1.00, a handful of pebbles which is free, a folded up piece of clean cloth, free, a small filter from a window screen or pasta strainer this would cost about $2.00, and tacs or a rubber band to hold the screen in place which on average cost, $1.99. The reasoning behind the multiple filtration components is to strain the water while keeping harmful pollutants out. For example, in the educational video we watched there was talk of many dead animals in the Ganges; to counter this we decided to include the window screen. As far as the rocks, we thought that it would benefit us to use a natural filter as opposed to exclusively a cloth and window screen. The thought process behind the cloth is that it will be the final filter that gets rid of any of the leftover pollutants and bacteria, and as far as we can see it works very well.

Snow Science
Reflection
Snow science is relevant to my life in that it teaches me to look for danger and how to recognize it. I not know how to avoid getting caught in an avalanche, should I ever be out in the mountains in the snow. In the American West water and snow are important for more than you would expect. The snow melt is the main supplier for the year's water, which is used for almost everything such as running water, recreational activities, watering grass and farms, electricity, and drinking. This means if there is not a huge snowfall, then the water supply will suffer for most of the year until there is more snow. Through this project I developed the skill of being knowledgeable on the topic of snow, and knowing how to avoid danger. I learned more about the environment, and how we are misusing it at the moment. I enjoyed making the poster, which was fun to get creative with, and I got to use my markers. I did not enjoy taking so many notes, and I don't think my attention span is that long. |
The Water Rocket Project
Summary
My rocket is designed to be functional yet creative, therefore I have based the design off of a shark. There are two fins at the bottom, and one in the middle. They are all spaced equally apart, so that they are still functional as rocket fins. The overall design of the rocket is simplistic, and not overly excessive.
I chose to test the pressure on my rocket, to see if it went higher with more pressure or less pressure. It seemed simple, just pump more after each test. My question was “Will the rocket fly better with more pressure or less pressure?” My hypothesis was “If more pressure is added, then the rocket will fly fly higher but it will not go as straight because it will have more thrust, but it will have less control.”
For the first test I used 40 psi, to start lower and work my way higher. The rocket went decently high, but it could go further. For the next two tests, I raised the pressure by ten. The second test had 50 psi, and the third test had 60 psi. It flew best with 60 psi, because it went higher. I wasn’t able to control what the weather was like, for instance one test it was raining, and another it was sunny. This might have affected the results some, that and launching in a couple of different places.
In the end, we decided to not use my rocket. Instead, we used my partner Avory’s rocket. It had a parachute, the fins were more effective, and it looked nicer. This turned out well, considering it was in the top five.
