Wave Project
Color Identification with Minimal Light
Introduction
The goal of our experiment is to find out which colors can be see easiest by the human eye with limited light. While using our background knowledge of waves we constructed a question that involves light waves. Instead of just looking at how light affects the human eye identifying color we looked into how minimal light would affect this. We wanted to see if limited light waves would have any affect on how easy colors are too see. During the experiment we discover that everyone's eyes and ableness to identify colors vary dramatically however we still got solid results partially proving our hypothesis.
Question and Hypothesis:
What color can be identified easiest by the human eye with minimal light?
If someone is asked to identify a color with minimal light, then the colors yellow and red will be most identifiable because they are the brightest and stand out the most.
Materials:
Dark Room (no light leaking through)
Test subjects
6 colors on construction paper (purple, green, yellow, blue, brown, red)
computer with changing brightness
Procedure: claire eats poop and so does joci
The controlled variables of this experiment are the colors and setup of the experiment while the uncontrolled variable is the brightness of the computer screen needed to see the colors.
Discussion:
In our experiment our intentions were to see out of 6 six different colors which were the easiest to identify in minimal lighting.Overall we found that the green and yellow were the easiest. The experiment was helpful because it demonstrated the eyes way of conception of color and which ones have more difficulty to define in dim light. We believed that the bright colors were going to be identified the easiest. what we did not know was that brown was going to be the harder one. I thought it was going to be blue or a darker color. This was interesting because it was a lighter color too.The independent variable affected the dependant because the distance could depend on how many times you have to guess. If we wanted to add onto the project. Our final results were important because it gave us a clear thought about how the human eye is different to each other and how they identify colors.
Abstract :
The motivation behind this test was the desire to discover what colors stimulated the human eye the best under low light conditions. Our question that we investigated was: What color can be identified easiest by the human eye with minimal light? We went about this test by going into a rom with no light. Then we showed the test subjects 6 different colors and had them identify the color while we amplified the light continuously. We then calculated how many times we had to up the brightness and then we wrote them on our Google Docs. The results that we got were that red, yellow, and green were the easiest to see. Brown was the hardest. This means that under a small amount of light brown is the hardest to see. Red, yellow and green are the easiest to see. This helps advance scientific research because it shows us which colors are easy to see and what are not. This is useful because now companies that make apps can choose colors that are easier to see, in contrast, to using colors that are difficult to see.

Procedure: claire eats poop and so does joci
- Hang 1 of the 6 colors on the wall in a dark room
- Have the test subject sit on the opposite side of room
- Turn off lights and have a computer screen (white) with brightness all the way down
- Have test subject identify the color while adjusting the brightness up until they guess right
- Record data of how many guesses it took
- Repeat this for all 6 colors with no variables changed.
The controlled variables of this experiment are the colors and setup of the experiment while the uncontrolled variable is the brightness of the computer screen needed to see the colors.

Water Filter Project
We were tasked to make a water filter. We had been assigned an area and we had to make a filter for that area. We had Nova Scotia.
Click here to see the area description.
Snow science is relevant in my life because I live in Durango, CO and I enjoy snow sports. If I don't understand the snow I am in danger whenever I go outside in the winter. Snow and rain have a huge impact in the American Southwest. In contrast to the East, you do not own the water on your land the water belongs to the country and is decided among the states in the Southwest. This is called water allocation. Most of the water goes to Colorado then Arizona. If we don't have enough rain their will not be enough water for the Southwest.
I did not develop any skills through this project. It was a waste of time because I don't give a crap about the water in the Southwest. I plan on leaving the first chance I get. I enjoyed being able to work by myself on this project. I really didn't like the whole premise of this project. There weren't enough guidelines so you could write about pretty much whatever you wanted as long as it pertained to weather.

POL-First Semester
Rocket Project- Katie Yeager, Claire Leffler, Gavin Syme
Introduction:
Each person from our team made individual rockets, but the rocket we chose to represent our team was Claire’s. Claire’s rocket is constructed from two Smart Water bottles fused together, because the Smart Water bottle has a very small, sleek form, two fused together result in an aerodynamic two liter design with the upper nozzle acting as a nose cone. Four fins in the shape of a pizza slice constructed from an old record are placed on all sides of the rocket, creating a square-like shape. The material of the fins is both thin, and nearly indestructible, hence help i’m a bug the fins on our rocket are both aerodynamic and reliable. Holding the fins in place is a base layer of duct tape, and a significant amount of glue, assuring that the fins will not fall off of the rocket during testing. Though my rocket was a close second, and Gavin’s was very stable, Claire’s rocket was selected for the project because it flew the highest. When tested, my rocket displayed a forty-three degree angle of elevation, Gavin’s portrayed a thirty-six degree angle of elevation, and Claires flew at a magnificent sixty-three degree angle of elevation.
The variable we decide to test was the water amount because it would help us find the most efficient way to fuel our rocket.
Question: How much water should be in a bottle rocket for it to achieve its maximum altitude?
Hypothesis: If a 2 liter bottle is filled up ⅓ of the way with 60psi then it will fly the highest because the amount of water will be enough to fuel it but not slow it down.
To test our variable we took a graduated cylinder and willed our rocket with 250 mL of water, 500 mL of water, etc… we found that the optimal amount of water was 1000 mL in a 2 liter bottle half way full.
Conclusion:
After a series of multiple tests, my group (Claire, Gavin, and myself) came to the conclusion that maximum height is achieved with approximately 1 L of water. Our tests showed that adding too much water does not leave enough room for sufficient air pressure, and therefore does not fly as high. The team conducted six experiments, all at sixty PSI, and measurements taken at twelve meters from the launcher. The first test in which no water was used, the rocket flew at 7.4 meters. The second test in which .25 L of water was used (the amount estimated to fly the highest in our hypothesis) flew to 10.8 meters. The third test with .50 L of water flew to 13.3 m, the fourth holding .75 L of water flew to 18 m. The fifth test containing 1 L of water flew to a magnificent 21.6 m, and the final test with 1.25 L of water only flew to 12.0 m. Throughout our tests, we made improvements to our other rockets (not our test subject); for example, after our first test we came to the conclusion that duct tape is very useful in making sure the rocket does not break, fall apart, get water damage, or explode. For other students doomed to do this project, We recommend the use of two smart water bottles for the reason that all rockets built from these seem to fly the highest.
We collected this data by using different tools to accurately answer our question “how much water should be put in a bottle rocket?”. Each time we tested the rocket all of our variables stayed the same accept the amount of water inside the rocket. Every time we had a pressure of 60psi. We used a measuring tape to make sure we were 12 meters away from the launch pad each time we measure how high our rocket went. I used a device to measure the angle accurately sometimes with one other person. After we collected our data I thought a scatter plot graph would best show our results. The obvious peak in the graph shows where we found the most success testing the amount of water in our bottle rocket.
