In my previous blog, I did a little bit of research on two types of instruments that I thought I might be playing, which were a violin and a guitar. However, after talking with my group, I chose to pick a different instrument so that there would be a balance between string and percussion. The instrument that I will be focusing on in this blog is a flute.

Sound is produced by this instrument when air is blown into the mouth piece which creates a wave of air to flow through. The air behaves like a stiff spring and as the player continues to blow, the spring receives those pulses and begins vibrating. As the wave vibrates through the flute, sound is created.

Based on my understanding, in order to change the pitch of the sound, the player must place their fingers on different holes on the flute, to alter the flow of air, which changes the wave and therefore changes the pitch.The characteristics that are important in this instrument are, a hollow tube through which air can pass through, small holes on one side of the flute, and an opening through which a person can blow air into the instrument.

I have done some research and it seems as if the simplest way to make a flute would be out of PVC pipes because it provides a good hollow structure for air to easily travel through and for sound to be made, also it is relatively easy to find. My plan for constructing the instrument is to borrow some PVC pipes from VK's  engineering room and then carve small holes on the top, and a mouth piece on one end. 

As of now, I don't have any outstanding questions regarding my instrument or this project. I would like to continue learning more about waves so that I can better my understanding of how music is created through instruments.

To make sound with a Recorder, you lightly blow into it. To change the pitch of the sound emitted from the recorder, you cover up the holes that are located along the recorder using your fingers. You cover up a hole, or several of the holes depending on what note you want to play.

The materials I plan on using to build my Recorder is PVC Piping and a drill. I will use the PVC Piping as the actual Recorder itself, and use the drill to drill holes into the PVC so that I can change the notes I am playing as I please. However, the only problem I have is exactly where I should drill the holes so that I can play different notes when using it. Does the size of the whole matter? Does the position of the holes effect the type of notes it will play?

The xylophone produces sound through force hitting the bar, where the vibration travels through the bar and into metal tubes called resonators. This is why the xylophone looks like it contains a vertical counterpart similar to the actual wood keys. These are important characteristics in a xylophone. To change the pitch, you strike a different key, arranged in octaves like a piano.

I intend on using an old computer frame stand as the base of my xylophone. I would only create one full octave because the frame is not as large as others, and the keys and bars would be made out of polished wood. For the resonators, it would be ideal to use metal pipes, but I would like to try using wood or plastic (PVC) to see what happens. I will play my instrument by using a mallet and hitting on the keys. I would use my time at home and Engineering class to build my instrument.

A lingering question I still have is: How will I separate each and every key while having it suspended on the computer frame?

My instrument, a simplified "Hammered Dulcimer":
The instrument is played by hitting strings with a small metal mallet. When the mallet hits the string, it causes the string to vibrate. This vibration sets off a wave in the air molecules - a sound wave. The different strings of the instrument produce different waves, and therefore different pitches. For example, a more tightly pulled string will produce a higher frequency wave, which results in a higher pitch. Important physical characteristics of the instrument include something to tune the strings with, so that I can make sure they produce the right wave frequency. Another important characteristic is the mallet, because that is what causes the strings to vibrate. I think that I need to have some kind of base that will make the sound more audible, but I'm not sure how. Maybe something like a guitar – a hollow wooden construction. I'm not sure. I'm not sure what kind of material is best to use for the strings, but I think I'll use a spool of "string wire". I'll need wood for the base of the instrument and also a stick of wood for the handle of the mallet. I'll need some metal for the head of the mallet. I kind of want to try to use bridges as well, but I'm not sure how those work. I need to do a bit more research into that topic.

My name Isn't important, everyone calls me blaze, even before all of this...maybe I should start at the begining, I had a wife, and kids, like everyone else...all eleven of us. I was a police officer, and I loved my life...but now its all over. They say its the end of the world, but all I care about is killing now. They took everything from me. being the only police officer in the group of survivers though makes me in a leader position, I had to train these men, and I have to make sure tey live. Its bullshit, I want to fight, I want to kill. but for now I'm just a diplomat. My name is Blaze, and this is my zombie Apocalypse journal day one

​For the 1^st quarter our benchmark for statistics was to calculate the consumer price index for different grocery stores. The Consumer Price Index is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. It measures changes through time in the price level of consumer goods and services purchased by households.

 

 We worked in groups of three to collect prices of different grocery store items. My group investigated Shop Rite, Acme, and Fresh Grocer. We collected prices on items like bottled water, cereal, ice cream, bread, and chips. We used statistics by calculating the mean prices for each item in each store. After we got the mean we calculated the five number summary and IQR’s for the items. We displayed our information on box plots and histograms. We calculated this information for all three grocery stores.

 

This benchmark helped me better understand grocery store prices. It helped me choose which store was more beneficial to shop at when it comes to saving. I learned that all stores are not the same. Sometimes prices differ because of the brands of food or just because of where it is sold. I noticed that the same items that were sold at Acme and Shop rite were considerably lower than the items sold at the Fresh Grocer. We connected this to the neighborhood the Fresh Grocer was in. Stores in wealthy neighborhood tend to have higher prices.

 

How it connected to the core values:

 

·      Inquiry: Are question was to find the consumer price index of different grocery stores.

·      Research: We each went out to different stores to collect prices of different items.

·      Collaboration: We worked in a group of three.

·      Presentation: We presented our findings to the class in a keynote

·      Reflection: We included reflection questions in our presentation to show what we learned from the project. 

New stem cell research might lead to more cloning experiments especially after the breakthrough with Dolly the sheep. Also stem cell research is leading to curing many diseases. Many experiments they do on animals have showed superb results that will soon be taken to the human stage to see if those experiments show good results also. They have been doing experiments on many animals but sheep and rats show the best results because they are cloning sheep and curing many diseases that the rats have.



In this diagram you can see that the have used stem cell research on rats to stop heart failure.

I am making a bass guitar it is played most of the time using the fingers,but a pick could also be used if the person so choose.The tension on the strings produce a note and you are able to change the note thought pressing on the fret bored at different points.The waves it produces is sound wave that most of the time have a deep undertone.

spencer is cute as fuck.

For my capstone, I decided to teach a debate class, at a K-8th grade school named Folk Arts Cultural Treasures. It required a lot of work including lesson plans, proposals, and many other things. I have provided the link to all the work I have done throughout the year. During my presentation I will a binder with all of these documents as well.

I watched a man play the piano the other day. It was one of the most amazing things I’ve ever heard. The man pressed the keys in order to produce a wonderful sound from the piano. With every stroke of the keys a different note was struck, becoming lighter and deeper as he moves along the piano keys. From the look of piano, I’d say the shape of it has a lot to do with the quality of sound and pitch of the notes produced by the piano. I think from the way the keys hit the stings it tells whether or not the pitch is high or low. I think if I design an instrument to mimic the way the keys hit the stings I’ll get the same tone and notes.  I know that sound travels in compressional  waves, this means that the vibrations of the strings are so fast that its able to travel so far and be so loud.

 

During my senior year in statistics the most memorable benchmark was the last one, which was the study guide. This benchmark is my most favorites due to the fact that it’ll help me in the following year with the endeavors that I’ll be taking on. They study guide applies past math courses to my future thus ultimately helping me and creating a guide throughout the class Math 101.  Since the class entails statistics the math in the guide was based off of stats and the combination of some algebra.  The statistics part consist of the following Probability & Simulations, Chi –Squared, Real number, Logic, Equations, Correlation & Causation, Bi-variate Data and Observational Studies.  I learned various tolls that I once did not comprehend such as the correlation and causation. Once introduced to this term I was still unsure what this actually meant until practice questions and mini quiz I found that Correlation is like domino affect one thing has to affect another to have a correlation or relationship. In having to do the benchmark and applying what I know all comes back to the core values SLA set up inquiry, research, collaboration, presentation and reflection.  I researched my future college and what course I’d be taking and what concepts I’d need to grasp in order to make my study guide. Collaborated with my peers to exchange some ideas to help my Q4B with the math tools needed for representation. Presentation I did I n a regular word doc instead of any other applications because I wanted the raw math to be displayed instead of a picture with some fragments a clear explanation was needed. Reflection was overall me just looking at my work with some feedback in my meeting with Thompson and actually looking over what I’ve done thoughtfully in my high school career.

​ To remind you of what we talked about in my last blog, I chose to build a guitar of my own for my physics project. In this blog post I will talk to you about the sound vibrations, pitch and the materials I will need to use to build my instrument. 

Sound from a guitar is produced by plucking or strumming the strings which are all different sizes to my understanding there are six strings on guitar and each strong makes a different sound while holding your finger down on different sections of the neck. When you pluck or strum the strings the strings vibrate from where your finger is on the neck down to the end of the body of the guitar.

To change the pitch of my instrument I will have to adjust the machine heads also known as the tuners, I would have to turn these tuners to the left or the right in order to get a high or low pitch. There are many parts to a guitar but I think the important physical characteristics would have to be 16 out of the 20 parts of the guitar.

1. Headstock
2. Nut
3. Machine heads (or pegheads, tuning keys, tuning machines, tuners)
4. Frets
5. Truss rod
6. Inlays
7. Neck
8. 8.     Body
9. 9.     Pickups
10. 10.   Electronics
11. 11.   Bridge
12. 12.   Pickguard
13. 13.   Soundboard 
14. 14.   Sound hole
15. 15.   Strings
16. 16.   Fretboard (or Fingerboard)
17. 
    

To build this guitar I will need wood to build the body, some plastic pieces for different parts of the guitar, some twisted screws for the machine heads, wire and thin metal piping for the fret board and I will need different sized plastic string for the actual strings of the guitar. All of these materials should be able to cover the necessary components of the guitar.

I will construct this instrument in my Advanced Engineering class that way I have all the materials I need at my fingertips, If that time id not enough I will also take extra time out of my day to stay after school to try to complete the guitar.

 As I've told you before my topic is on animal abuse. It’s a growing problem. My Mom had a cat that suffered from animal abuse. My mom had a cat that was a semi – indoor semi- outdoor cat.  One day her cat didn’t come home, so naturally my Mom to look for him. She found him in an ally crushed under a cinder block he was still alive. That cat suffered to death. Now I’m not saying that the person was evil he could have been a kid trying to impress his friends. That though doesn’t excuse the fact that he hurt another living thing. A lot of animal abuse comes from people who don’t know how to take care of their pets properly. Most cases of animal abuse stem from people who forget to feed their pet or that they even have one. Hoarders are also an issue
