Wave project
Title: Vibrational Water
Abstract: We wanted to test our theory that the higher the frequency of a sound wave the more intricate the interference patterns would be in a liquid medium. So we decided to take a set of speakers and connect them to a tone generator. Then we placed a tupperware on the speakers. We then poured 5mm of water into the tupperware. We started at a frequency of 140 and stopped at a frequency of 300. Our results were those which we expected.
Hypothesis: The higher the frequency the more intricate the interference patterns will be.
Intro:In this experiment we are trying to test if the higher the frequency the more intricate the interference patterns. The concepts needed to understand in this experiment are how sound waves work and how they produce vibrations differing depending on the higher or lower the frequency. Our estimated outcome is that as we make the frequency higher the more intricate the interference patterns will be. Sound waves work almost the same way as any other type of wave. They have frequencies and bounce off of mediums. The higher the frequency in a sound wave the smaller the vibration is produced. This allows for more intricate patterns. This is the reason our experiment worked.
Methods and Materials: Speaker, Paint, Water, Other substances as we see fit and a tone generator. First we hooked up the tone generator too the speaker and then places a tupperware with 5mm of water onto the speakers. We tested this twice. We could clearly see the interference waves. The next test we did was changing depth of the water in the tupperware. We made it 10mm instead of 5mm and tested it twice aging. We could barely see very tiny splashes in it. It almost looked like the water was static. Next we did a test with 5mm of water with paint mixed with the water. The paint made it look really cool but other than that it didn’t change it. We then made the depth 10mm of water and paint mixed. The results were the same as the previous tests with 10mm of water.
Results:
The results were that as the depth of the substance got deeper the less you could see the patterns on the water. The 5mm patterns could easily be seen while the 10mm patterns couldn’t.
The results were that as the depth of the substance got deeper the less you could see the patterns on the water. The 5mm patterns could easily be seen while the 10mm patterns couldn’t.
Discussion:
Our experiment was to test if the frequency of a sound wave affects it ability to make interference patterns in a substance. The results were that the deeper the substance the less you can see the interference patterns. This means that it takes a more powerful speaker to make interference patterns in a thicker substance. We are confident in our results because we tested them and saw that with our own eyes that they were true. We can improve the experiment by using more substances that differ in density. We can also improve the experiment by testing more depths than just two. It would greatly increase the amount of data that we have and possibly change our results.

Rube goldberg
Rube Goldberg Main Point of Interest Questions-Ryan Colley, Robert Haggart, Ari Liberman.
-How did you go about designing your rube? (Show your initial draft design, show a video of another rube that inspired you)
The begin designing our Rube Goldberg, we downloaded the software Google Sketchup and made a 3D model of our soon to be contraption. After spending around 4-5 hours on the program creating our 3D model, we completed the model and started writing our steps down on a piece of paper. After all of that was complete, we began construction on our Rube Goldberg which we completed a week or two later.
-What steps were most challenging to make it work? (How did you troubleshoot or redesign?)
The most challenging step that we had to complete was the pulley system that we had to create in order to launch the catapult. We could not generate enough force to pull the catapult down to the point of launch. We eventually asked our physics teacher Brian for help and he suggested to put a weight in one of the boxes and have the marble knock the box off of the trap which ultimately worked better.
-What skills did you learn?
Some of the skills that we learned while creating our Rube Goldberg we teamwork and construction skills. Creating a project of this magnitude really helped us get more acquainted with more power tools as well as the construction aspect of construction and measurements. It also helped learn more about teamwork and how relying on each other can be a big risk but it pays off in the end. This project has taught us more about teamwork and construction.
In Physics our assignment was to come up with a testable experiment to solve a question we were wondering. My group did "the affects of music on reading comprehension." Throughout this project I improved on not procrastinating and doing work even if I may not want to. In the beginning of the year i would put off homework and not do it but during this project I improved on getting to work and motivating myself.
"the affects of music on reading comprehension" project
We chose this because we found solid evidence amongst many articles. We did this because we wanted to do a different type of test than other groups and brian recommended that this might work. I read a few articles about how music helps focus and work pace but I found no information on how music affects reading comprehension so it made me curious. To test this we decided on a simple method, to have a reading comprehension/analysis test. We would write a short story and five questions from the story, we would then distribute 20 of the tests. Ten to a safety group without music. And ten with music.
Question and Hypothesis:
Our question was, “how does music affect your reading comprehension?”
Methods & Materials To begin we wrote a short story and five questions from the story, we then distributed 20 of the tests, ten to a safety group without music, and ten with music. We played rap music. The materials were used were as follows: headphones (volume of the user's choice), ipod, pen/pencil, our short story, and 5 questions from the text. We took both the subject groups outside where there was no distractions or interruptions.
Results we found in the proposed test that we subjected to the general animas high school population of 20 students. We also found that the people who took the test with earbuds had highest scores by a landslide, When testing we put the earbuds and non earbuds subject in a quiet environment to make sure that the test would be fair ass far as the comparison between the two. We graphed the results as shown below with quite the amazing final product that proved our groups expectations right just as our hypothesis has shown
Discussion I think in the experiment that we did, it showed the expectations that we followed and how we did the project in a reasonable state. The project also carries great relevance with a lot of reasoning that is important for us as a group, I also think that our project carries value to the school for the music policy especially in our test results. The experiment was formed in the first place for the benefit of all school students who enjoy music, we also found the reasoning to prove that music can be a helpful addition to class work that is innocent and relaxing. Our group was expecting music to take the win as far as increasing productivity, we also expected the test to show just how much music can benefit people in a classroom such as a certain set of mind that allows focus. The data that we collected from the test shows that the general music test takers have a higher score on each and every question than the non music test takers. So we came to the conclusion that music can increase the productivity to an individual rather than working without music.
We expected that music would help test takers and it did out of the 20 people that we tested the 10 that listened to music took the test seriously and took to mind what the text said. We also found that the test concluded the results to show that the tests with music had an average of 7.2 on each question while the non music test takers averaged around 4.4 quite the difference.
The results on the experiment mean a lot to us as a group because the prove our claims and suggestions to the school about the music policy. We are fairly confident in our results do to the test design begins how hard, or how you need to remember key terms….etc.
An even further way to test music in reading comprehension could be to choose a different type of test instead of reading comprehension, such as we could test cross word puzzles because “everyone hates them” - Big XL Brian Phillips Morgan.
